Pneumatic Steam Dart Arbalest 752

From:
Lineage 684 of the Gem Crested Karthian of Archaic

    * Equipment Classification: Two-Handed Held Ranged Weapon, requiring both hand slots to properly support, aim, and discharge.     * Tier and Rarity: Tier 1, Common quality.     * Attunement and Action Economy: Automatically undergoes instantaneous handheld attunement upon being lifted into a firing grip. Firing the weapon expends one combat action, which includes unhooking the weapon from its shoulder harness, drawing a quarrel from an ammunition case, seating the bolt into the enclosed flight groove, and releasing the sear. When an avatar with two actions fires the arbalest as their second action, the base damage and tier die pass-through are reduced to one-half total output. If an adversary hits the arbalest with a targeted equipment attack, the weapon is deactivated and unattuned, demanding a ten-minute uninterrupted ritual before it can be re-engaged in combat.     * Attack, Range, and Ammunition Mechanics: Operates under the Extended ranged format categorized as Extended (40/80). The standard operational range is 40 feet, within which attack rolls suffer no spatial penalties. The range can be extended up to an absolute maximum of 80 feet, but targeting any foe beyond 40 feet requires halving the attack chance amount rolled (rounding down to the nearest whole number before comparing the result against the target's total Armor Check). Firing beyond 80 feet results in an automatic miss. The attack roll utilizes a d20 plus the avatar's Tier 1 tier die (1d4), with the tier die passing directly into the damage total. The arbalest requires physical ammunition, depleting exactly one specialized survey dart or quarrels per attack. Accessing the dart from a waist quiver is an integral part of the attack action. Following the conclusion of combat, the avatar can reclaim 50% of the standard ammunition expended during the encounter by dedicating roleplay time to searching the battlefield; any fractions resulting from odd expenditures are discarded. The weapon inflicts 1d8 base piercing damage plus the 1d4 tier die result. If the avatar utilizes magical or alchemically charged ammunition, that special projectile is consumed upon firing regardless of whether the attack hits or misses the target's Armor Check.     * Durability and Health Points: Maintains a base resilience of 10, establishing a total pool of 33 Item Health Points (avatar maximum health points of 23 plus 10 resilience points). Sustaining damage that reduces the arbalest to 16 hit points or lower induces the broken condition, jamming the internal pressure valves and bowstring release, which prevents all further attacks until repaired by a qualified artisan. Reaching zero hit points destroys the stock, snapping the bow limbs and rupturing the pneumatic cylinder.     * Material Composition and Forging: Built around a dense, carved stock of straight-grained petrified ironwood fitted with brass barrel brackets and a steel trigger housing. The propulsive assembly features a laminated composite prod made of layered horn, spring steel, and flexible ash wood, drawn across an enclosed bronze track. Mounted beneath the stock is a compact, hand-pumped pneumatic compression cylinder fitted with a brass pressure dial, machined in the workshops of Syl-Kar. When primed via four strokes of an integrated under-lever, the cylinder stores pressurized air that supplements the mechanical release of the bowstring, propelling heavy lead-weighted quarrels with high velocity and minimal acoustic resonance. The weapon is fitted with a wide, padded shoulder stock contoured to rest securely against the Karthian's scaled clavicle plate without slipping against interlocking scales.     * Archaeological and Tactical Utility: Serves as a quiet, accurate projectile weapon ideal for eliminating troglobitic cave predators, subterranean bats, and ambush vermin along the high ceilings of unmapped ruin galleries without causing deafening echoes that risk triggering roof collapses or alerting hostile factions. For epigraphic fieldwork, the arbalest is frequently loaded with specialized survey darts trailing fine spools of braided linen cord, allowing the avatar to launch anchor lines across subterranean chasms, retrieve high-hanging architectural fragments, or hoist illumination lanterns into inaccessible vaulted canopies.

During
the deep subterranean surveys of the Second Consolidation, the
engineering detachments of Lineage 684 advanced into the vast, hollow
acoustic caverns beneath the Iron Sump and the fractured vaults of
the Lower Burrows. In these high-domed subterranean chambers,
standard firearm discharges, steam-vent charges, and even the
snapping prods of traditional heavy siege-arbalests proved
disastrous. The loud, concussive acoustic shockwaves echoed across
miles of interconnected limestone flues, dislodging unstable ceiling
vaults, triggering lethal shale-falls, and stirring colonies of
blind, echolocating cavern predators. Furthermore, architectural
surveyors required a reliable, non-destructive method to shoot
plumb-lines, illumination flares, and retrieve delicate structural
scrapings from high ceiling arches without pulverizing fragile
Precursor friezes.

To overcome these environmental hazards, Lineage 684 entered into a joint design contract with the pneumatic guild-foundries of Syl-Kar to engineer Batch 752. Drawing inspiration from municipal hydraulic pressure systems, the artisans paired an enclosed bronze flight track with a compact, hand-pumped compression reservoir mounted beneath a petrified ironwood stock. By using four quick strokes of an under-lever to pre-compress ambient air, the arbalest releases heavy leaded quarrels and anchor bolts on an expanding cushion of vapor, muffling the prod’s snap to an almost imperceptible hiss. Model 752 quickly established itself as the premier weapon for subterranean architectural scouts, proving instrumental during the survey of the Whispering Gallery of Vault 9, where surveying teams eliminated lurking ceiling troglobites and rigged cross-chasm suspension spans without waking the hibernating drakes resting in the fissures below.

• Specific Slot:
  • Two-Handed Held Slot (occupies both primary hand and off-hand slots when actively shouldered and fired; stows into an over-shoulder swivel harness across the dorsal carapace when not drawn).
• Tier One Stats:
  • Equipment Classification: Two-Handed Held Ranged Weapon / Archaeological Survey Launcher.
  • Tier and Rarity: Tier 1, Common Quality.
  • Base Resilience: 10 resilience points.
  • Item Health Points: 33 Item HP (Avatar base maximum HP of 23 plus 10 resilience points multiplied by the Tier 1 modifier). Sustaining damage that reduces the pool to 16 HP or below causes the broken condition, jamming the compression valves and bowstring sear until repaired; permanently destroyed into scrap bronze, wood, and steel at 0 HP.
  • Attunement Dynamics: Instantaneous handheld attunement upon lifting the weapon into a firing grip; does not count against the standard ten-item attunement ceiling. If targeted and disarmed in combat, the weapon powers down immediately, requiring a 10-minute uninterrupted ritual attunement before it can be wielded again.
  • Action Economy: Consumes 1 complete combat action (unhooking from shoulder harness, drawing a quarrel from a quiver, seating it into the enclosed bronze flight groove, aiming, and releasing the sear).
  • Multi-Attack Diminishing Returns: If an avatar with two actions fires the arbalest as their second action in the same 6-second combat turn, the base damage and tier die pass-through are reduced by half.
  • Range Classification: Extended (40/80). Standard operational range is 40 feet with no penalties. Long range extends from 41 to 80 feet, during which the attack chance amount rolled is halved (rounded down) before being compared against the target’s Armor Check. Targets beyond 80 feet result in an automatic miss.
  • Attack Roll: 1d20 + 1d4 (Tier 1 Tier Die) + Dexterity modifier + Ranged Proficiency bonus. The total result must strictly exceed the target’s Armor Check to hit. A natural 1 triggers an automatic miss and a Failure card draw; a natural 20 triggers a critical hit and a Crit card draw.
  • Damage Output: 1d8 base piercing damage + 1d4 (Tier Die, piercing damage).
  • Ammunition & Recovery: Expends 1 specialized survey dart or quarrel per attack. After combat, the avatar can reclaim 50% of standard expended ammunition by searching the field (discarding fractional remainders). Alchemical or magical ammunition is permanently consumed upon firing regardless of whether the attack hits or misses.
  • Physical Mass: 8.5 lbs.
• Skills Gained While Openly Worn or Held:
  • +1 Temporary Skill Point to Subterranean Ballistics & Ceilings Marksmanship (improves targeting elevation, trajectory compensation, and lead-angle calculations against perched or climbing cavern vermin in zero-light conditions).
  • +1 Temporary Skill Point to Spelunking Rigging & Traverse Launching (enhances line placement, anchor seating, and tension calculations when firing tether darts, grappling heads, or hoisting lines across chasms).
• Multiple Passives Magic:
  • Acoustic Vapor Baffle: The weapon absorbs and disperses the mechanical snap of the bowstring and the hiss of expanding air into a low, localized whisper. Discharges generate no acoustic resonance through surrounding rock, preventing weapon-induced cave-ins and concealing the wielder from enemies relying on echolocation or vibration-sensing beyond 10 feet.
  • Pneumatic Bore Guidance: The enclosed bronze flight track releases an expanding vapor cushion ahead of the projectile, eliminating rail friction and stabilizing the dart against subterranean downdrafts, steam plumes, and thermal turbulence within the 40-foot standard range.
  • Pneumatic Seal Diagnostics: The wielder intuitively perceives the cylinder’s internal pressure and valve seal health via the Mind’s Eye, receiving real-time warnings of pressure drops or mechanical grit fouling before a shot is taken.
• Multiple Activatable Magics:
  • Superheated Steam Discharge: The wielder channels thermal mana into the compression cylinder before releasing the sear. On impact, the dart vents a burst of scalding vapor, dealing an additional 1d6 fire/force damage and forcing the target to make a physical resilience check or be blinded for 1 round by burning steam. Possesses 2 charges per day; regains all expended charges daily at dawn.
  • Pneumatic Line Retraction: When firing an anchored survey dart trailing braided linen cord, the wielder expends 1 action to engage a reverse-cycle vacuum inside the pneumatic cylinder. The mechanism reels in up to 250 pounds of suspended weight (or hauls the avatar across a chasm) at a rate of 20 feet per round for up to 1 minute. Possesses 2 charges per day; resets after a long rest.

Acquisition,
Commerce, and Valuation of the Pneumatic Steam-Dart Arbalest 752

• Methods of Obtaining the Item:
  • Excavation of Second Consolidation Acoustic Vaults and Drainage Flues:
    • Avatars surveying the cavernous chambers beneath the Iron Sump, the flooded ventilation galleries of the Lower Burrows, or the high-domed recesses of the Whispering Gallery of Vault 9 can discover intact Model 752 arbalests inside locked municipal survey lockers, sealed transit crates, or resting beside the skeletonized remains of lost expeditionary teams.
    • Securing an intact specimen requires clearing petrified mud and sulfur encrustations from the brass cylinder housing, testing the under-lever stroke to verify the leather compression seals have not dried out, and using the Mind’s Eye to confirm that the laminated prod’s composite horn and ash layers have not suffered dry-rot or delamination.
  • Municipal Requisition and Department of Public Works Logistics:
    • Licensed architectural surveyors, deep-shaft scouts, and bonded municipal contractors working under the Department of Public Works or the Guild of Masons and Antiquarians can requisition a Model 752 prior to descending into acoustically sensitive subterranean sectors.
    • Drawing the arbalest requires presenting an authorized expeditionary warrant and locking an equipment surety bond through the avatar’s World Bank ledger account, receiving the weapon directly from central logistics alongside a standard quiver of lead-weighted survey darts.
  • Lineage Workshop Bestowal and Ballistic Apprenticeship:
    • Within Lineage 684 and affiliated pneumatic engineering clans of Syl-Kar, the arbalest is conferred as a masterwork milestone weapon from an elder surveyor-mechanic to a journeyman marksman upon the completion of their first acoustic-strata mapping tour.

Tactical
Environmental Roleplay: Defensive and Offensive Applications of the
Pneumatic Steam-Dart Arbalest 752

• Subterranean Burrows and Catacomb Vaults beneath Syl-Kar:
  • Defensive Applications:
    • In acoustic cavern vaults such as the Whispering Gallery or unstable shale flues beneath the Iron Sump, standard firearm concussions or snapping siege-prods trigger catastrophic ceiling cave-ins. The Acoustic Vapor Baffle muffles the release to a muted hiss, preventing shockwaves from vibrating through fractured limestone arches and shielding the wielder from echolocating predators or vibration-sensitive troglobites lurking beyond 10 feet.
    • When cavern scavengers or blind mire-leeches drop from overhead fissures, the padded clavicle stock allows the avatar to shoulder and fire the arbalest in narrow, low-clearance crawlways without catching the bow prods on jagged wall outcroppings.
    • If a subterranean floor collapses into a boiling sulfur pit or deep sump, the avatar fires a specialized survey dart trailing braided linen cord into a ceiling strut. Engaging Pneumatic Line Retraction reels the 365-pound avatar up at 20 feet per round, lifting them out of toxic gas pools or surging flash-flood waters.
  • Offensive Applications:
    • The avatar snipes perched troglobites, giant cave bats, and sentries clinging to high vault ceilings up to 80 feet away. The heavy lead-weighted quarrel punches clean through thick chitinous carapaces, pinning targets to rock faces without producing alerting echoes.
    • Against charging chitinous horrors or rogue mining automatons in narrow adits, the wielder discharges a Superheated Steam Discharge. The dart releases a high-pressure cloud of scalding vapor on impact, burning through soft sensory antennae, blinding visual clusters, and softening mineralized shells for follow-up strikes.
    • In unmapped ruin complexes, the avatar launches anchor quarrels across impassable chasms or collapsed bridge spans, securing stable guide-ropes to pull traversal lines, hoist luminescence lanterns into dark domes, or retrieve high-hanging Precursor frieze fragments.
• Mist-Veil Mountains and Alpine Scree Slopes of the Boreal Reach:
  • Defensive Applications:
    • Alpine switchbacks are plagued by fierce mountain gales, downdrafts, and thermal shears that knock light arrows off course. The Pneumatic Bore Guidance system discharges an expanding vapor pocket ahead of the projectile, stabilizing the heavy quarrel and ensuring pinpoint ballistic accuracy across 40-foot standard mountain ranges despite howling crosswinds.
    • When descending crumbling shale slopes or crossing fractured ice shelves, sudden scree slides can sweep an explorer into bottomless glacial crevasses. The avatar shoots an anchor dart into solid granitic bedrock above, using the line as an instantaneous arrest cable and engaging Pneumatic Line Retraction to haul themselves back up the cliff face.
    • Confronted by charging alpine predators on narrow two-foot ledge trails, the avatar triggers Superheated Steam Discharge into the snowpack directly ahead of the beast, flashing snow into an impenetrable blinding vapor screen that halts the charge before it reaches melee distance.
  • Offensive Applications:
    • The avatar engages diving alpine raptors, harpies, or crag-drakes circling overhead before the beasts can enter their dive-bomb trajectory, driving heavy piercing quarrels through wing joints to ground the flying predators on distant scree beds.
    • When engaging mountain bandits positioned on switchbacks across a ravine, the wielder fires at long range (up to 80 feet), cutting guide-ropes, severing pack-mule tethers, or disabling hostile scouts without weapon flash or loud reports revealing the sniper’s high concealment blind.
    • To neutralize hostile encampments sheltered under precariously balanced hanging ice cornices or loose rock overhangs, the scholar fires a lead-weighted quarrel directly into stress fractures, triggering targeted rockslides and avalanches to bury enemy positions below.
• Primordial Rootwood Forests and Canopy Settlements:
  • Defensive Applications:
    • Operating in the high canopy thousands of feet above the forest floor carries the perpetual danger of rotting branches and severed suspension footpaths. If a moss-covered limb snaps under the avatar’s weight, the scholar draws and fires a tether dart into an adjacent ironwood trunk; the Pneumatic Line Retraction immediately engages, braking the fall and winching the explorer safely to a sturdy branch.
    • In dense arboreal jungles, firing loud weapons stirs aggressive swarms of giant canopy hornets and territorial predators. The weapon’s whisper-quiet report ensures that defensive shots taken against stalking wood-panthers or strangler-vines do not provoke the broader ecosystem into a feeding frenzy.
    • When trapped in dense briar knots or wrapping constrictor coils, discharging Superheated Steam Discharge into the plant matter parboils and wilts tough vascular fibers, forcing thorny vines to release their grip.
  • Offensive Applications:
    • The enclosed bronze flight track and rigid prod assembly prevent leafy brush, hanging moss, and creeping vines from fouling the bowstring during discharge, allowing the marksman to shoot through dense jungle foliage without arrow deflection.
    • Firing across the massive spans between giant ironwood trees, the avatar uses the arbalest to establish rigging tethers and high-altitude zip-lines, allowing surveying parties to traverse from canopy platform to canopy platform without descending to the predator-choked forest floor.
    • Against canopy raiders hiding behind woven wicker shields or hollow tree trunks, the lead-weighted quarrels punch through dense bark and light timber shoring, disabling snipers in elevated tree nests.
• Sunken Glades and Brackish Wetland Marshes:
  • Defensive Applications:
    • Navigating the salt-marsh estuaries and mangrove swamps of the Glade Coast ruins standard bows and black-powder weapons through moisture rot, wet cordage, and damp fuel. The petrified ironwood stock, brass brackets, and sealed pneumatic cylinder (Glade-Iron Non-Fouling lineage metallurgy) remain completely unaffected by water immersion, mud splatter, or acidic marsh vapors, firing reliably in torrential rains.
    • When wading through chest-deep mangrove channels, the avatar is vulnerable to underwater ambushes by giant lungfish and sulfur-leeches. The silent arbalest allows the wielder to eliminate surface-skimming predators before they breach, without alerting predatory reptiles basking along the riverbanks.
    • If trapped in sucking peat bogs or quick-mud sumps, the scholar shoots an anchor dart into sturdy mangrove root networks, using Pneumatic Line Retraction as an automatic mechanical winch to drag their 365-pound mass out of the bog onto firm ground.
  • Offensive Applications:
    • Firing into dark, brackish delta pools, the heavy leaded quarrel retains sufficient kinetic momentum to pierce through several feet of murky water, spearing armored mud-snappers and predatory gar that standard hunting arrows would deflect off.
    • Against river-pirate skiffs or raider pirogues attempting to escape down mangrove channels, the avatar fires an anchored line into the target vessel’s gunwale and engages the reverse-cycle vacuum. The arbalest winches the light boat backward against the current or drags it onto submerged coral snags to capsize the raiders.
    • When targeting thick-scaled marsh basilisks or giant snapping turtles, the avatar unleashes Superheated Steam Discharge, blasting scalding steam beneath their belly plating to bypass heavy dorsal shells.
• Urban Industrial Megacities and Steam-Tram Corridors of Syl-Kar:
  • Defensive Applications:
    • In crowded industrial sectors, tenement corridors, and pressurized boiler hubs, firing conventional explosive or concussive weapons risks rupturing overhead high-pressure steam mains or igniting ambient coal dust. The arbalest’s pneumatic discharge releases only clean, contained vapor, eliminating spark and open-flame ignition hazards.
    • In narrow tenement alleys and multi-tiered mechanical shafts, the avatar uses the weapon to maintain vertical mobility. When pursued by city watch patrols or street syndicates, firing a tether bolt to an overhead steam-tram rail allows Pneumatic Line Retraction to rapidly hoist the wielder up out of melee reach into the dark pipe rafters.
    • The padded clavicle stock absorbs recoil and prevents the weapon from slipping against the wielder’s scaled shoulder plates when taking defensive snap-shots in moving freight elevators or jolting steam-trams.
  • Offensive Applications:
    • Operating within cavernous boiler halls and tram depots, the marksman eliminates saboteurs, corporate agents, and rooftop sentries across 40-foot catwalks with complete acoustic concealment, masking the weapon’s discharge beneath the background rhythm of industrial stamping engines.
    • Confronted by heavily armored municipal enforcers or rogue security automatons, the avatar activates Superheated Steam Discharge. The boiling vapor cloud penetrates eye-slits, ruptures rubber hydraulic seals, and fogs optical targeting crystals, blinding combatants and stalling mechanical joints.
    • In close-quarters industrial raids, the scholar launches grappling darts through high skylights, iron security grates, or freight crane pulleys, creating rapid ascent routes to bypass locked warehouse gates and reinforced perimeter barricades.

Perception
of Activation:

• User’s Perspective:
  • Somatic and Tactile Sensations: The moment both scaled hands raise the arbalest into a firing posture—one hand gripping the petrified ironwood stock around the trigger housing and the other cradling the forward bracket beneath the brass cylinder—instantaneous handheld attunement takes hold. A deep, steadying warmth sinks through the palmar scales, locking the wielder’s forearms and shoulders into an immovable triangular shooting platform. The padded clavicle stock contours seamlessly against the Karthian’s thick collarbone plate, distributing the weapon’s 8.5-pound mass so evenly that it feels weightless and rigid, eliminating muzzle wobble without bruising interlocking shoulder scales.
  • Auditory and Vibrational Sensations: A crisp, pressurized click-hiss vents through the internal relief ports as the pneumatic cylinder seats its charge. A rhythmic, ultra-low acoustic thrum pulses from the brass pressure housing into the wielder’s ribs—a soft vibration matching the wielder’s respiration, confirming that the four-stroke compression cycle is fully held behind the bowstring sear.
  • Olfactory and Gustatory Sensations: The snout registers the dry, mineral scent of petrified ironwood mingled with hot valve grease, boiled tallow seal dressing, and the sharp, warm tang of pressurized copper-tin bronze. An arid, faintly ozonic vapor coats the back of the palate, like inhaling air near a subterranean steam vent.
  • Extra-Sensory Perception — Pneumatic Seal and Structural Telemetry: The avatar’s Mind’s Eye instantly projects a clear internal schematic of the weapon. It registers at 33 out of 33 Item Health Points, its base resilience fixed at 10, and its Tier 1 classification verified. The display highlights internal pressure curves within the compression cylinder, confirming that the leather cup seals are lubricated, the enclosed bronze flight track is true, and the horn-steel-ash prod lamination is under uniform mechanical tension with zero micro-fractures.
  • Extra-Sensory Perception — Ballistic Trajectory and Windage Overlay: Looking down the enclosed bronze flight groove, a faint, amber-hued trajectory line extends outward into the environment. The interface automatically calculates elevation angles, ceiling clearances, and thermal updrafts, showing an unimpeded flight path across the 40-foot standard range, while highlighting the halved accuracy calculation arc out to the 80-foot maximum limit.
  • Extra-Sensory Perception — Acoustic Dispersion Boundary (Vapor Baffle): The wielder perceives a translucent, spherical sound-dampening perimeter extending roughly 10 feet around the weapon. This mental indicator confirms that the Acoustic Vapor Baffle is actively suppressing the mechanical prod snap, ensuring that loose cave shale, hanging stalactites, and vibration-sensitive tunnel vermin beyond the boundary will not register the shot.
  • Extra-Sensory Perception — Reserve Mana Monitoring: In the corner of the wielder’s awareness, the primed magical charges glow with distinct energetic signatures: 2 charges of Superheated Steam Discharge pulse like concentrated thermal coals within the valve manifold, while 2 charges of Pneumatic Line Retraction register as tightly wound, kinetic vacuum coils ready to reel in anchor tethers.

• Observer’s Perspective:
  • Visual Manifestations: As the wielder brings the arbalest to bear, the fine Syl-Runes etched along the brass pressure collar and down the sides of the enclosed bronze track flare with a brief amber glow that settles into a soft, steady luminescence. A faint wisp of translucent vapor vents from the bypass valve below the stock and dissipates instantly into the air. The shooter’s posture noticeably drops and locks, muscles bracing against the ironwood stock with mechanical precision.
  • Auditory Manifestations: Bystanders hear only a sharp, mechanical click as the trigger sear sets, immediately followed by the faintest pneumatic sigh—a sound quieter than a drawn breath. The typical creak of drawn crossbow limbs and the sharp metallic slap of released bowstrings are completely absent.
  • Kinetic and Atmospheric Shifts: A tiny puff of warm, dry air fans outward across the floor beneath the shooter’s hands, stirring fine limestone dust in a gentle ripple before going completely still.

• Positives of Activation:
  • Instantaneous Attunement: Activates immediately upon establishing a two-handed firing grip, requiring no one-minute ritual delay and consuming none of the avatar’s ten-item attunement ceiling.
  • Complete Acoustic Concealment: The Acoustic Vapor Baffle muffles discharge resonance, eliminating the risk of weapon-induced ceiling cave-ins and concealing the shooter from blind, echolocating cavern predators.
  • Ballistic Stability: The Pneumatic Bore Guidance neutralizes rail friction and buffers the quarrel on an expanding vapor pocket, preventing drift from subterranean drafts and steam plumes within 40 feet.
  • Comprehensive Diagnostic Feedback: Continuous telemetry alerts the shooter to pressure drops, valve fouling, or prod fatigue before a shot is released.
  • Multi-Functional Tactical Utility: Provides immediate access to Superheated Steam Discharge for blinding armored threats and Pneumatic Line Retraction for chasm traversal, line rigging, and emergency ascension.
  • Fluid Operational Flow: Allows unhooking from the dorsal swivel harness, loading, aiming, and discharging within a single operational action.

• Negatives of Activation:
  • Two-Handed Requirement: Occupies both hand slots continuously during operation, preventing the simultaneous use of epigraphic chisels, handheld torches, shields, or secondary melee weapons.
  • Consecutive Attack Diminishing Returns: If fired as a second consecutive action within the same six-second combat round, the base damage and tier die pass-through are reduced by half.
  • Disarm Deactivation Vulnerability: If targeted and knocked from the wielder’s hands, the arbalest powers down instantly, demanding an uninterrupted ten-minute ritual attunement before its mechanisms and enchantments can be re-engaged.
  • Ammunition Consumption Constraints: Relies entirely on physical survey quarrels, only 50% of which can be salvaged after an encounter; specialized or alchemically treated ammunition is consumed on firing regardless of whether the strike hits or misses.
  • Luminescent and Thermal Signature: In pitch-black chambers, the faint amber glow of the runes and the heat radiating from the pressurized brass cylinder can be detected by predators sensitive to thermal gradients or low light.

Crafting
Recipe: Pneumatic Steam-Dart Arbalest 752

• Materials Needed:
  • Straight-Grained Petrified Ironwood Blank: A thirty-inch cured, defect-free billet of petrified ironwood harvested from the Rootwood Marches, air-seasoned and oil-treated to provide an unyielding structural backbone that will not warp under spring tension or subterranean moisture.
  • Machined Brass Compression Cylinder & Valve Stock: Three pounds of cast bronze and cartridge-grade brass stock, utilized to turn the main pneumatic chamber, under-lever pump arm, check valves, and the casing for the dial gauge.
  • Enclosed Bronze Flight Track: Two pounds of low-friction copper-tin phosphor bronze, extruded and broached into a precision-milled enclosed guide channel to enclose the quarrel flight path.
  • Composite Prod Materials:
    • High-carbon spring steel strip (twenty-four inches long, two inches wide, one-eighth inch thick).
    • Boiled mountain-ram horn plates (split and scraped to taper toward the tips).
    • Seasoned white ash backing laths (providing elastic flex and snap).
  • Bowstring Cordage: A continuous length of high-tensile braided wire-core linen cord, served with waxed thread at the center nocking loop.
  • Dire-Boar Leather & Felt Padding: Scraps of dense boiled wool felt and oil-dressed dire-boar hide to line the contoured clavicle buttstock and to form lubricated internal piston cup-seals.
  • Alchemical Lubricant and Valve Sealant: Four ounces of refined tallow, boiled whale oil, and pine pitch mastic to coat internal compression packings and prevent high-pressure air leaks.
  • Sacrificial Ranged Weapon (Component Ingredient): One mundane Tier 1 light crossbow, heavy sling, or shortbow, broken down and transmutatively dissolved in the alchemical basin to transfer its baseline 1d8 damage profile and base resilience into the arbalest.
  • Tier 1 Magic Crystal Catalyst: One charged, flawless magic crystal of the first circle (the size and weight of a silver coin) to anchor the Acoustic Vapor Baffle, Pneumatic Bore Guidance, Superheated Steam Discharge, and Pneumatic Line Retraction enchantments.
• Tools Required:
  • Precision Machine Lathe and Bench Tackle: Foot-powered or steam-driven treadle lathe, brass-turning chisels, thread-cutting taps and dies, reamers, and dial-calibration calipers.
  • Woodcraft and Joinery Kit: Drawknives, rasps, cabinet scrapers, mortise chisels, inletting gouges, and a padded bench vise.
  • Bowyer’s Lamination Press and Hearth: Heat-resistant wooden cauls, iron screw-clamps, hide-glue double-boiler, charcoal tempering furnace, and an oil-quench trough for heat-treating the spring steel prod.
  • Leatherworking and Packing Tools: Hole punches, skiving knives, burnishing sticks, and brass assembly rivets.
  • Epigraphic Graver and Stylus: Hardened steel burins calibrated for fine Syl-Rune engraving across brass and bronze surfaces.
  • Transmutation Basin: A shallow granite trough filled with mineralized brine for mana channeling and sacrificial dissolution.
• Skill Requirements:
  • Pneumatic Machining & Clockwork Engineering: Minimum of 4 trained skill points to turn pressure cylinders, cut true valve seats, fit leather piston packings, and assemble the four-stroke under-lever mechanism without pressure bleed.
  • Weaponsmithing & Bowyer Craft: Minimum of 3 trained skill points to forge, taper, and laminate the steel-horn-ash composite prod, ensuring balanced limb flex without twisting or hinge points.
  • Woodworking & Ergonomic Inletting: Minimum of 3 trained skill points to carve the petrified ironwood stock, cut the internal receiver mortises, and contour the padded buttstock to fit scaled Karthian clavicle anatomy.
  • Syl-Rune Epigraphy & Geomantic Binding: Minimum of 3 trained skill points to scribe acoustic dampening channels, align the pressure runes, and set the magic crystal core.
  • Mind’s Eye Diagnostic Proficiency: Capability to project and monitor internal stress lines, verify seal tolerances under compression, and bind the weapon’s 33 Item Health Points and 10 base resilience.
• Crafting Steps:
  • Stock Profiling, Mortising, and Clavicle Bedding:
    • Mount the thirty-inch petrified ironwood billet in the bench vise. Using drawknives and rasps, shape the stock with a wide fore-end, a drop-comb grip, and an arched cheek rest.
    • Contour the rear buttstock into a broad, concave plate engineered to distribute recoil across an avatar’s scaled clavicle plate without shifting.
    • Mortise the top surface to receive the enclosed bronze flight track and trigger sear box.
    • Inlet a deep under-channel beneath the fore-end to house the pneumatic compression cylinder and the pivoting under-lever linkage.
    • Sand the stock smooth using progressively finer pumice, finishing the ironwood with boiled linseed oil to seal the grain against subterranean moisture.
  • Machining the Pneumatic Compression Cylinder and Valves:
    • Chuck the brass cylinder casting into the lathe. Bore and hone the interior wall to a mirror finish, ensuring uniform bore diameter along its eight-inch stroke length.
    • Turn the brass piston head, cutting twin circumferential grooves to seat the lubricated dire-boar leather cup-seals.
    • Machine the forward valve manifold with a one-way intake check-valve, a high-pressure discharge port aligned with the flight track, and a threaded socket for the brass pressure dial.
    • Pin the folding under-lever linkage to the piston rod and cylinder base, calibrating the stroke ratio so that exactly four complete pumps generate full operating chamber pressure.
    • Thread the pressure dial into the manifold, calibrating the indicator needle to register operating readiness.
  • Forging and Laminating the Composite Prod:
    • Forge-temper the twenty-four-inch high-carbon spring steel strip, tapering the width from two inches at the center to one inch at the tips. Quench in oil and draw the temper to a spring-blue resilience.
    • Prepare the ash belly laths and mountain-horn backing plates, scoring the mating surfaces with a toothing plane to promote mechanical adhesion.
    • Warm the components, apply hot hide-glue between the layers, and bind the horn-steel-ash assembly inside the curved wooden lamination caul using iron screw-clamps.
    • Allow the glue to cure under continuous pressure for forty-eight hours.
    • Shape the limb tips, carve string nocks, and wrap the center of the prod with treated sinew to reinforce the mounting block.
  • Extruding and Fitting the Enclosed Bronze Track:
    • Mill the phosphor bronze flight track with a covered slot configuration that encloses the quarrel’s shaft while leaving a top clearance slit for the cock feather or stabilizer vane.
    • Profile the rear of the track to integrate with the steel trigger housing and roller-nut sear.
    • Align the cylinder discharge port directly behind the quarrel’s nock position, allowing expanding vapor to vent directly into the flight groove behind the seated projectile.
  • Epigraphic Inscription and Crystal Catalyst Integration:
    • Using the steel graver, cut acoustic-dispersion Syl-Runes along the outer flanks of the bronze flight track and encircling the brass pressure collar.
    • Carve a recessed seating cavity into the underside of the stock directly behind the valve manifold.
    • Bed the charged Tier 1 magic crystal into the cavity with warm pine pitch mastic.
    • Scribe fine conductive lines from the crystal seat to the valve assembly, completing the mana circuit required to fuel the Acoustic Vapor Baffle, Superheated Steam Discharge, and Pneumatic Line Retraction properties.
  • Sacrificial Transmutation and Structural Transference:
    • Place the sacrificial Tier 1 ranged weapon into the granite transmutation basin alongside the arbalest components.
    • Channel mana through the Mind’s Eye to initiate the dissolution ritual, breaking down the sacrificial weapon’s form to feed its structural resilience (10 points) and baseline 1d8 damage profile into the newly forged steel prod and brass cylinder.
    • Allow the discharged mana vapor to settle into the bronze track and ironwood stock until the metal and wood show a faint amber sheen.
  • Final Mechanical Assembly and Prod Rigging:
    • Bed the pneumatic cylinder into the lower stock channel, securing it with through-bolts and brass reinforcing brackets.
    • Fit the enclosed bronze flight track into the upper mortise, bolting it through the stock into the steel trigger casing.
    • Seat the composite prod into the forward ironwood nose, locking it firmly in place with an arched bronze nose-cap and twin retention wedges.
    • String the arbalest with the wire-core linen cord, drawing the string across the track to rest against the roller sear.
    • Rivet the dire-boar leather wrap and felt shock-padding onto the contoured clavicle buttstock.
  • Pressure Testing, Calibration, and Attunement Harmonization:
    • Cycle the under-lever through four firm strokes; verify on the brass dial that the cylinder holds pressure for ten minutes with zero gauge bleed.
    • Load an unweighted survey dart, prime the sear, and execute a test discharge into a stone barrier. Confirm that the Acoustic Vapor Baffle suppresses the string slap to a low whisper and leaves no acoustic echo through the floor.
    • Open the Mind’s Eye: verify that the completed weapon registers 33 out of 33 Item Health Points, locks into Tier 1 operational status, and establishes instantaneous handheld attunement the moment both hands assume a firing grip.

Silent
Cloud-Spitter and Brass Lung Which Brought Forth Iron Line Across Pit
of Screams
Rendered
from the Crumbled Parchments of the Deep Burrows by the Hesitant Hand
of Scribe Mor-Vath

In the seasons when the Second Gathering-Together did push its stone-borers through the lowest ribs of the mountain, the surveyors of the Four-and-Eighty and Six Hundred [translator note: Lineage 684, who held the imperial patent for deep surveying and cavern epigraphy] did come upon the Great Hollow which is marked upon the black maps as Vault Nine, known also among the old diggers as the Whispering Gallery of the Deep Chimneys.

Now that cavern was not built like the sturdy stone cellars of Syl-Kar, where the granite is thick and dull to the hammer. The ceiling of Vault Nine was arched five hundred paces above the mud, wrought of thin, singing limestone and sheets of brittle black shale that had been baked by ancient volcanic fires until they were taut and fragile as the skin of a war-drum. If a miner did but strike his iron crow against a flint nodule, the ringing sound would run through the stone ribs for four leagues, and the ceiling would cast down great showers of razor-sharp shale like hail from a winter cloud. And if an explorer did discharge a fire-spitter of black powder or let loose the horn-prod of a great wall-arbalest—whose thick sinew-string clappeth against the timber with a sound like a thunder-stone—the whole sky of the cavern would shiver, tear itself loose, and bury an entire guild-company beneath forty thousand loads of shattered rock.

Yet the peril of the falling stone was but half of the curse. For in the floor of Vault Nine there lay the Great Cleft, an unmeasured crack that went down into the sulfurous grease of the Iron Sump; and within that warm crack slept the Brood of the Blind Flitter-Drakes. These were creeping, winged serpents of forty cubits length, without eyes in their skulls, but having upon their snouts three hundred velvet cups that could hear the scurry of a blind beetle half a league away through the dark. When any loud sound broke the quiet of the gallery, the Flitter-Drakes would wake from their mud-beds and rise like a black cloud through the steam, spitting burning grease and tearing the heavy drag-tails of the surveyors with their hooked claws.

In that season, many brave scouts did perish on the high hanging scaffolds. For when they sought to shoot measuring-lines across the Great Cleft unto the far cliff—where the ancient clay tablets of the First Consolidation hung upon the walls—their cord-throwers would snap with loud cracks, or the heavy iron darts would go astray in the rising heat-winds, and the scouts would be left marooned without ropes while the blind drakes tore them from their ladders.

Then came forth a master of the bellows and the string, whose name was Tor-Kaelen the Straight-Horned, an elder artificer of the Four-and-Eighty and Six Hundred, whose scales were grey as furnace-slag and whose right shoulder bore the heavy calluses of thirty winters spent upon the survey lines. Tor-Kaelen had seen his two hatch-brothers cast down into the sulfur pit when an apprentice dropped a brass measuring-rod; and he swore by the Deep Fire that he would build a weapon of distance that would speak no louder than the breathing of an infant, yet have within its belly the kick of an elder ox and the reach of an eagle’s eye.

Tor-Kaelen went into the deep lumber-caves where the managed timber of the Rootwood Marches is cut by water-saws. There did he choose a timber of petrified ironwood thirty spans in length, straight as a mason’s chalk-line and black as the mud of a peat-bog. This wood was not light like river-drift; it had lain under the press of the mountain until its veins were turned to stone, so that the wetrot of the sump could not warp it, nor could the strongest claw dent its bark.

Out of this black trunk did he carve the stock of the arbalest. He gouged the butt with a deep hollow, lining it with the boiled wool of the high mountain sheep and covering the wool with the brain-tanned hide of the marsh boar, cutting the leather with cross-slits that it might hold fast to the chest. For he said: “When the surveyor of seventy stones’ weight [translator note: the 365-pound mass of the Karthian dragon-folk] doth plant his snout to take aim across the black air, the butt must not dance upon his breast-plates, nor bruise the tender joint where the clavicle-shell meeteth the throat.”

Upon the upper back of the timber he mortised a long channel and laid within it an enclosed pipe of red phosphor-bronze, having a slit only wide enough to let the thin bronze feather of the quarrel pass through. For Tor-Kaelen knew that if a quarrel be cast upon an open rail, the wild air-eddies of the steam-clefts will catch the tail and turn the iron from its path; but within an enclosed bronze tube, the bolt rideth straight as an arrow through an oil-vat.

Then went he to the brass-founders of the Lower Aqueducts and commanded them to turn an air-pot of thick brass, having an eight-inch stroke and walls that could endure four hundred pounds of vapor-press without bursting. Beneath the belly of the stock he hung this brass lung, joining it to a double crank of iron that tucked neatly beside the trigger. With four strokes of this crank—chuff, chuff, chuff, chuff—a man could cram the breath of forty cubits of cavern air into the brass bottle, until the little brass eye upon the dial pointed straight to the mark of danger.

For the bow-prod itself, Tor-Kaelen would have neither simple steel that breaketh in the subterranean cold, nor horn alone that turneth soft in the steam. He took a ribbon of blue spring-steel, hammered thin as a knife-blade, and between two plates of split ram-horn he laid laths of white ash-tree, gluing the whole together with the boiled sturgeon-skin of the Glade Coast under four iron screw-presses for sixty days. When the string of wire-plaited linen was drawn back to the roller-sear, the three-fold prod bent with a terrible, sweet tension, holding within its curve the power to pierce three shields of boiled leather.

Now beneath the nose of the brass lung he fitted a secret maze of bronze baffles, packed with oiled sheep-felt and powdered pumice [translator note: an early form of pneumatic expansion chamber and acoustic suppressor]. When the iron trigger should let slip the roller-sear, the compressed wind of the cylinder did not rush forth in a roaring blast, but was caught in the felt maze, expanding softly like the sigh of a sleeping ox, while pushing behind the bolt with an unyielding shove that drove the projectile through the bronze groove without the prod slapping the stock.

When the engine was whole, Tor-Kaelen took it unto the consecrated granite basin where the line-masters do their enchantments. He laid the tool in the brine alongside a light hunting-cross of five fathoms’ pull, which had seen twenty battles, and he crushed a sun-stone of the first circle [translator note: a Tier 1 magic crystal] upon the bronze dial. He spoke the three words of the Void-Barrow, until the spirit of the old hunting-bow fled its wooden bones and entered into the steel-and-ash prod, and the light of the sun-stone sank down into the brass lung, turning the air-needle golden beneath the glass.

He marked the brass housing with the line-number Seven-Hundred and Two-and-Fifty.

And lo! When Tor-Kaelen did lift the heavy piece with both claws, setting his right hand upon the boar-skin grip and his left beneath the brass lung, there was no need to light three tallow-sticks or mutter seventy lines of prayer. Instantly, in the very heartbeat when his claws touched the stock, the bond was sealed. A cool, steady wind ran through his scaled forearms; the runes upon the bronze tube glowed yellow as amber in a dark room; and within his Mind’s Eye there opened a glowing line of sight that stretched forty paces into the cavern gloom, showing him the true path of the dart through the falling mist, with all the drafts and vapors of the abyss reckoned to a hair’s breadth.

Then went Tor-Kaelen with four surveyors of his lineage into the mouth of Vault Nine.

The darkness in that place was thick as grease, and the silence was like a drawn knife. Far below in the Great Cleft, the warm mud bubbled—plop… plop…—and from the ceiling, five hundred cubits up, the thin limestone sheets hung like the knives of a thousand guillotines. Across the chasm, sixty paces distant, upon a high shelf of basalt, rested the Precursor Lintel, whereon were carved the ancient water-codes that would save the Second Consolidation from drowning.

Yet between the party and the shelf lay only empty air and the stench of sulfur.

Suddenly, an apprentice pointed a trembling claw upward into the gloom.

High upon the hanging stalactites above the scaffold, three cave-monsters—which the miners call the Scythe-Clawed Ceiling-Stalkers—had crept down from the chimneys. They were beasts with six jointed legs, having shells of black shale and mandibles like sheep-shears, crawling upside down upon the roof with their bellies swollen with poison. They were creeping directly above the hemp ropes that held the surveyors’ platform; in three breaths, their shears would sever the cords, and the four scouts would tumble five hundred paces into the mouth of the mud-drakes below.

Had any man raised a shout, the sleeping Brood-Mother in the pit would awaken. Had any man loosed a common war-bow, the snapping prod would shake the singing ceiling, and the limestone would rain down and butcher them where they stood.

Tor-Kaelen stepped to the rail of the scaffold. He planted the curved ironwood butt against the hard scales of his right clavicle. He set his left claw to the under-crank: chuff, chuff, chuff, chuff. The brass needle on the belly-dial swung to the yellow glyph. He drew a quarrel of heavy Glade-iron, tipped with lead to give it weight in the mist, and slipped it into the bronze tube. The sear clicked into place like a key in an iron lock.

He raised his muzzle; his Mind’s Eye traced the amber arc through the darkness, compensating for the thermal rise of the sulfur steam.

He squeezed the iron horn of the sear.

There was no clack of wood on wood. There was no whistling snap of cord. Only a tiny, muffled breath—phut-t-t—like the sound of a bubble bursting in warm grease.

From the enclosed bronze pipe, the heavy leaded dart shot forth on a cushion of dry vapor. It crossed forty cubits of empty black air without a flutter, striking the foremost Ceiling-Stalker squarely between its eight eyes. The heavy Glade-iron point punched through the shale-shell and pinned the beast’s skull to the solid granite ceiling. The monster shuddered; its six claws curled inward; and it died upon the roof without releasing its grip, hanging limp and motionless like a dried bat.

The apprentices held their breath; not a grain of dust fell from the fragile ceiling; the Brood-Mother in the pit stirred not a claw.

Again Tor-Kaelen set his arm to the under-lever: chuff, chuff, chuff, chuff. A second bolt went into the bronze pipe. Phut-t-t. The second monster was nailed through its gullet to the stone arch, its shears snapping once in the dark before its heart-blood ceased to beat.

Yet the third beast, seeing the death of its kin, took fright and let go its hold upon the ceiling, falling like a dropped anvil into the Great Cleft below.

It struck the edge of the lower mud-shelf with a wet, smashing sound that echoed through the lower flues like the breaking of an earthen jar.

Immediately, from the deep bowels of the sulfur cleft, there arose a terrible, wet breathing.

The Great Blind Brood-Mother of the Flitter-Drakes was awake.

The black mud churned; a vast horned snout, broad as a coal-barge and covered with weeping sensory cups, rose through the steam. The beast had no eyes to see the hunters upon the scaffold, but its three hundred velvet pits turned upward, tasting the sound of their trembling scales. The monster spread its great webbed sails of skin and began to climb the slick basalt wall, its talons tearing grooves four inches deep into the stone, dragging its forty cubits of bloated belly toward the scaffolding.

To make matters more desperate, the vibrations of the falling beast had loosened the far suspension anchor. The hemp guide-line across the chasm snapped with a sharp thwack, and the young apprentice who held the surveyor’s transit was left clinging with two claws to a single frayed rope over the boiling mud, screaming in terror.

Tor-Kaelen did not drop his weapon, nor did his scaled hands shake upon the stock.

He reached into his leather side-case and drew out the long survey quarrel—a rod of tough ash-wood bearing a barbed four-toothed head of slate-tempered bronze, trailing a spool of three-hundred-span braided linen cord, thin as grass-silk but strong as cattle-leather.

He set the dart into the enclosed track and clipped the tail of the flax to the brass winding-drum beneath the cylinder.

Chuff, chuff, chuff, chuff. The lung was primed.

He took aim not at the monster, but at the ancient Precursor Lintel across the yawning gulf. He pulled the sear.

The dart leaped across sixty cubits of steam. The barbed bronze point struck the mortar-joint of the Precursor arch, burying its four wings deep into the ancient lime until the steel teeth locked into the stone like the roots of an oak tree. The linen cord pulled taut through the air, hummed once with a clear, bell-like tone, and hung straight as an iron rail over the pit of sulfur.

“Seize the cord!” hissed Tor-Kaelen in the ear of the hanging apprentice.

The youth caught the flaxen line in his claws. In that same instant, Tor-Kaelen invoked the second enchantment of the weapon and shouted the word of the Inward-Wind.

The Pneumatic Line Retraction took hold of the brass lung!

The cylinder reversed its breath with a ferocious, sucking gasp. The winding-drum spun like a weaver’s spool. The linen line whistled as it flew backward, hoisting the three-hundred-pound body of the apprentice up out of the chasm like a fish drawn on a silver hook, depositing him safely upon the timber flags of the upper gallery in the space of three breaths!

Yet the sound of the line had drawn the Brood-Mother. Her vast, horned snout breached the rim of the upper shelf not five paces from the scaffold. Her jaws opened wide, showing four ranks of curved yellow teeth dripping with green gall, and she drew in the cavern air to spit a deluge of burning oil upon the company.

Tor-Kaelen stood upon the very edge of the abyss. He did not reload a bolt of wood or lead.

He laid his hand upon the brass pressure collar and channeled the heat-mana of his own dragon-blood directly into the compression manifold.

He invoked the Superheated Steam Discharge!

The water-fumes inside the bronze lung flashed into boiling fury; the needle of the brass dial spun past the red glyph and broke its stop-pin. Tor-Kaelen leveled the open muzzle of the bronze track straight into the gaping, sensitive throat of the Brood-Mother and tripped the emergency relief valve.

A blinding, boiling cloud of superheated white vapor—hot as the breath of a smelting furnace and dense as winter fog—blasted from the bronze pipe in a screaming cone.

The scalding steam engulfed the snout of the monster. The three hundred velvet hearing-cups upon her skin were withered and parboiled in an instant; her soft throat-tissues blistered and choked with white blisters; her sensitive nostrils were scorched shut. Blinded, deafened, and crazed with the agonizing burn of the steam, the great serpent shrieked a soundless shriek, thrashing her great neck in the air.

Her claws slipped from the greasy basalt shelf. She lost her purchase upon the stone; her forty cubits of bulk turned over in the mist, and she tumbled backward into the bottomless mud of the sulfur pit, crashing down through the dark until the grease swallowed her forever.

Tor-Kaelen lowered the arbalest.

Around them, the fragile ceiling of Vault Nine hung intact. Not a single plate of razor-shale had fallen; not a single stalactite had snapped from its ancient root; the singing limestone remained as silent and undisturbed as the tomb of a forgotten king.

The four scouts drew their measuring slates in the quiet room. Across the taut linen line which the arbalest had cast, they pulled their iron car, reached the Precursor Lintel, and transcribed the sacred water-codes of the First Consolidation before the third bell of the watch had rung.

When they returned unto the council-terrace of Syl-Kar, they laid the Seven-Hundred and Two-and-Fifty upon the cedar table before the Master of the Public Works. The master looked upon the petrified ironwood stock, the enclosed bronze track, and the brass lung with its cracked needle, and he decreed that this engine should be recorded in the Great Ledger of Iron as the father of all subterranean marksman-tools, commanding that wherever the rock was thin and the monsters had sharp ears, no surveyor should go forth without the silent breath of the Seven-Hundred and Fifty-Second hanging from his shoulder-swivel.

Moral of the story: He who seeks to conquer the dangerous places by making a great noise and shaking the earth with his fury shall find that the mountain is bigger than his chest and will surely fall upon his head; but he who holds his breath, walks with a muffled tread, and carries an engine that can strike like a viper and cast a line like a spider in the absolute dark shall cross the widest chasm in peace, while the blind terrors of the world drown in their own silence.

  • Action Economy & Draw: Firing requires 1 Action (unhooking from shoulder harness, drawing a quarrel, seating it into the enclosed track, and releasing the sear).
  • Consecutive Attack Diminishing Returns: If you make a second attack with this weapon on the same turn, the base damage and tier die pass-through of that second attack are halved.
  • Ammunition & Salvage: Expends 1 specialized survey dart per shot. You can recover 50% of expended mundane darts by spending 10 minutes searching the battlefield after combat. Specialized or alchemical ammunition is permanently consumed upon firing.
• Attunement Constraints:
  • Instantaneous Handheld Attunement: You attune to the arbalest instantly upon assuming a two-handed firing grip; while held, it does not count against your standard maximum attunement limit.
  • Disarm Deactivation: If an effect or creature successfully forces you to drop or disarm this weapon, it immediately deactivates and becomes unattuned. You cannot benefit from its magical properties or fire it until you complete a 10-minute ritual attunement during a rest.
• Passive Properties:
  • Acoustic Vapor Baffle: The arbalest produces no mechanical snap or concussive echo. Its discharge is completely silent to any creature farther than 10 feet away, and firing cannot trigger acoustic tremors or cave-in hazards.
  • Pneumatic Bore Guidance: Your ranged attacks with this weapon ignore cover penalties and disadvantage caused by non-magical winds, steam vents, or thermal updrafts within 40 feet.
  • Pneumatic Seal Diagnostics: You intuitively know the arbalest’s current structural integrity (33 Item HP; broken at 16 HP or lower) and whether its internal pressure seals are intact.
• Active Properties:
  • Superheated Steam Discharge: When you hit a creature with a ranged attack using this weapon, you can expend 1 charge to vent scalding steam on impact. The target takes an additional 1d6 Fire damage and must succeed on a DC 13 Constitution saving throw or be Blinded until the end of its next turn. This property has 2 charges and regains all expended charges daily at dawn.
  • Pneumatic Line Retraction: When you fire a tether dart trailing braided cord into a solid surface, you can expend 1 charge as an Action to engage the internal vacuum winch. The arbalest reels in up to 250 pounds of suspended weight (or pulls you toward the anchor point) at a rate of 20 feet per round for up to 1 minute. This property has 2 charges and regains all expended charges daily at dawn.

Knave (2nd Edition)

Steam-Dart Arbalest 752

• Item Slots: 2 Slots (requires two hands to carry and fire).
• Damage: 1d8 Piercing damage.
• Range: 40 ft / 80 ft. Firing at targets between 41 and 80 feet is made with Disadvantage (roll 2d20 and take the lower result, or halve the attack total). Firing beyond 80 feet is an automatic miss.
• Durability and Quality:
  • Quality: 4/4.
  • Item Health Points: 33 HP. Sustaining damage that reduces the arbalest to 16 HP or lower inflicts the broken condition, jamming the compression valves and bowstring sear until repaired by an artisan. Shatters completely at 0 HP.
• Ammunition & Salvage:
  • Requires specialized survey quarrels (1 Slot carries 20 bolts).
  • After an encounter, the wielder can recover 50% of expended mundane quarrels by spending an exploration Turn searching the area. Magic or alchemical quarrels are lost upon firing.
• Combat and Action Dynamics:
  • Instant Handheld Bond: Gripping the weapon with both hands instantly attunes it to the wielder without consuming attunement slots.
  • Action Economy: Loading, aiming, and firing consumes 1 full action. If granted a second attack in the same round, the damage dealt by the second shot is halved.
  • Disarm Deactivation: If disarmed by a foe’s maneuver or critical effect, the pneumatic cylinder depressurizes, deactivating all enchantments until the wielder spends 1 exploration Turn (10 minutes) recalibrating the seals.
• Passive Tactical Properties:
  • Acoustic Vapor Baffle: The arbalest is completely silent beyond 10 feet. Discharges never trigger dungeon wandering monster checks based on sound and cannot cause cave-ins or ceiling rock-falls.
  • Pneumatic Bore Guidance: Ignores adverse wind, updrafts, and mist penalties within 40 feet.
• Active Properties:
  • Superheated Steam Discharge: Once per day, the wielder discharges a scalding thermal bolt. On a successful hit, the attack inflicts +1d6 Fire damage, and the target must make a Constitution save or be blinded for 1 round.
  • Pneumatic Line Retraction: Once per day, the wielder fires an anchored survey bolt trailing strong cord. The pneumatic cylinder winches up to 250 lbs at 20 feet per round for 1 minute, allowing the wielder to cross chasms or ascend sheer cliffs.

Fate

The Pneumatic Steam-Arbalest 752

• Classification: Specialized Extra, Ranged Weapon, and Survey Rig Stunt Package (Two-Handed Implement).
• Aspect Integration:
  • Dedicated Item Aspect: Pressurized Bronze-Track Arbalest with Petrified Ironwood Stock. This aspect can be invoked to shoot with pin-point accuracy through steam and updrafts, launch anchor lines across subterranean chasms, silence weapon discharge in acoustic caverns, or blind an adversary with venting steam; it may be compelled to represent the encumbrance of a two-handed weapon in tight crawlways, the vulnerability to disarming deactivation, or a sudden loss of pneumatic pressure from damaged seals.
  • Inherent Burden Aspect: Two-Handed Pneumatic Rig. Requires both hands to aim, stabilize, and discharge, preventing the concurrent use of shields, climbing tools, or epigraphic implements.
• Handheld Attunement & Disarm Deactivation:
  • Instantaneous Handheld Attunement: Lifting the arbalest into a two-handed firing grip bonds the weapon immediately to the wielder without occupying personal milestone slots.
  • Disarm Deactivation: If an opponent successfully executes a disarm action against the wielder, the arbalest deactivates and unattunes immediately; its stunts and magical properties remain dormant until the character dedicates 10 minutes to uninterrupted bench calibration during downtime.
• Weapon Rating and Range:
  • Weapon:2: Inflicts 2 additional shifts of physical stress on a successful hit with Shoot.
  • Operational Range: Targets within the same zone or an adjacent zone suffer no spatial penalties. Targeting an adversary two zones away halves the effective shift value of the attack (or increases the target’s defense by +2). Firing beyond two zones is impossible.
  • Operational Draw Action: Readying the arbalest from its shoulder harness, drawing a bolt, seating it in the enclosed track, and releasing the sear is resolved within a single action.
  • Consecutive Shot Diminishing Returns: If granted an extra action to fire a second consecutive shot within the same exchange, the base weapon stress is halved (Weapon:1).
  • Ammunition & Salvage: Expends 1 specialized survey quarrel per attack. After the scene concludes, the character reclaims 50% of standard expended ammunition (rounding down odd remainders). Alchemical or magical bolts are expended permanently regardless of the roll outcome.
• Passive Tactical Mechanics:
  • Acoustic Vapor Baffle: The shot is completely silent beyond the immediate zone. Firing never creates alerting noise aspects, alerts vibration-sensing cavern horrors, or risks triggering ceiling cave-in aspects.
  • Pneumatic Bore Guidance: Ignores situational aspects and invoke penalties related to high winds, subterranean updrafts, or steam vents within standard range (up to 1 zone).
  • Pneumatic Seal Diagnostics: The wielder intuitively perceives internal pressure and structural integrity, receiving immediate warning of seal wear or valve fouling.
• Active Stunt Capabilities:
  • Superheated Steam Discharge: Twice per session (or by spending 1 Fate Point), the wielder channels thermal mana into the discharge manifold when releasing a bolt. On a successful hit, the attack inflicts +2 additional shifts of physical stress and creates the situational aspect Blinded by Scalding Steam with one free invocation.
  • Pneumatic Line Retraction: Twice per session, when firing a tethered survey bolt into a stone wall, lintel, or ceiling strut, the wielder engages the reverse-cycle vacuum winch. The arbalest automatically overcomes physical barriers, hoisting up to 250 pounds of weight or pulling the wielder across a chasm at high speed without requiring an Athletics roll.

Numenera & Cypher System

Pneumatic Vapor Arbalest 752

• Item Level: 3 (determines crafting target numbers, maintenance difficulty, and environmental interaction levels).
• Form and Structure: A straight-grained petrified ironwood stock fitted with an enclosed phosphor-bronze flight groove, a hand-pumped brass compression cylinder with a pressure gauge, a laminated composite prod (horn, spring steel, and ash), and a padded clavicle buttstock.
• Weapon Classification and Operational Flow:
  • Classification: Heavy Ranged Weapon (requires two hands; inflicts 6 points of damage).
  • Range: Short range (up to 50 feet; covers the 40-foot standard range). When firing at Long range (up to 100 feet; covering the 80-foot maximum), the attack roll is hindered by two steps. Attacking targets beyond Long range is impossible.
  • Operational Action Economy: Unhooking from the shoulder swivel harness, drawing a quarrel, seating it into the enclosed track, aiming, and firing is resolved as a single action.
  • Consecutive Attack Diminishing Returns: If an ability or asset allows a second attack with the weapon in the same round, the second strike inflicts half damage (3 points).
  • Handheld Attunement & Disarm Deactivation: Bonds immediately upon being held in a two-handed firing grip without counting against cypher or artifact limits. If forcibly disarmed, the cylinder vents and all enchantments power down until 10 minutes of quiet maintenance are spent recalibrating the seals.
  • Ammunition & Salvage: Consumes 1 survey quarrel per shot. After an encounter, 50% of mundane quarrels expended can be recovered by searching the area. Special alchemical or magical projectiles are consumed permanently on discharge.
• Depletion Rating: 1 in 1d20 (checked only upon activating Superheated Steam Discharge or Pneumatic Line Retraction; passive capabilities do not incur depletion rolls).
• Passive Tactical Capabilities:
  • Acoustic Vapor Baffle: The weapon releases no mechanical snap or concussive echo. Discharges cannot be heard beyond immediate distance (10 feet), easing stealth tasks to remain undetected while shooting by two steps and preventing weapon-induced acoustic cave-ins.
  • Pneumatic Bore Guidance: Eases ranged attack tasks hindered by subterranean crosswinds, steam vents, or thermal updrafts within Short range by one step.
  • Pneumatic Seal Diagnostics: Telemetry automatically informs the wielder of internal chamber pressure and confirms that the item maintains its full 33 Item Health Points (becoming broken and jammed at 16 HP or lower).
• Active Capabilities:
  • Superheated Steam Discharge (Action): The wielder channels thermal mana into the valve manifold upon firing. On a hit, the attack inflicts 3 additional points of damage (9 damage total), and the target must succeed on a Might defense task or be blinded for 1 round by scalding steam. Depletion: 1 in 1d20.
  • Pneumatic Line Retraction (Action): When firing an anchored survey quarrel trailing braided cord, the wielder engages the reverse-cycle vacuum winch. The arbalest hauls up to 250 pounds of weight (or pulls the wielder across a gap or up a cliff face) up to Short distance (50 feet) over 1 minute. Depletion: 1 in 1d20.
