Rarity: Common
Tier Availability: Tier 1 Compatible
Form: Finished Brew
Color & Appearance: A pale sky-blue liquid that appears deceptively thin. When the container is tilted, fine lines of white streak through the fluid like wind trails slicing across a clear sky. If left still, the brew swirls on its own once every few breaths, as though compelled by an unseen breeze.
Taste & Texture: Almost weightless on the tongue, with a faint coolness like inhaling high mountain air. Leaves behind a tingling sensation across the lips and cheeks, giving the impression that the face is being touched by soft wind even indoors.
Lore:
Among the zeppelin docks of the Wind-Run Cliffs and the airship platforms of the Levitation Guilds, engineers and glider pilots discovered that magic-infused wind obeys attention much like water obeys momentum. A minor alchemist-mechanist named Talla of the Bronze Feathers once remarked: “A bird does not push the wind—it agrees with it.” Inspired by this, Talla brewed a tonic not to grant flight, but to teach the body to stop fighting the air.
Originally offered to first-time glider apprentices and deck-runners working atop roaring airship hulls, the Slipstream Draught became a staple safety brew among those who dance atop ropes, sails, and hull plating. Despite its humble availability, many swear the first sip changes how they feel the world—like threads of wind begin to lace around their limbs, teaching them to move with less resistance.
Base Description:
The brew does not grant wings or magical lift. Instead, it tunes bodily awareness to air currents, improving agility and allowing faster adaptation to movement in high-wind or high-speed scenarios. Ideal for glider trainees, messenger riders, stormship crew, wind-sail racers, and rooftop runners between tether lines.

Passive Magic Effect (while active):
Wind Awareness: The drinker feels subtle shifts in airflow against their skin. Gain +1 to checks involving balance, dodging, gliding, riding air currents, or anticipating directional momentum (such as diving with a falling rope bridge, storm jumping, or avoiding gust-driven projectiles). Movements tend to feel smoother to the user—less clumsy, more flowing.
Active Magic Effect (once per drink):
Slipstream Step: Once during the duration, the user may declare a movement adjustment that uses airflow instead of brute force. This allows one reroll or advantage-like effect when making a movement or evasion attempt tied to wind, speed, or gliding trajectory—such as leaping, sliding under pressure, redirecting a fall, or adjusting stance on a fast-moving platform. Additionally, the user may ignore one minor penalty from strong winds or unstable footing as their body instinctively aligns with the current instead of resisting it.
If the user roleplays attuning to wind—pausing to breathe with gusts, shifting posture like a bird catching draft—the GM may allow the passive to last the session.
Places where and how this item might be bought and sold:
Airship Dockside Supply Booths
These small vendor stations are set up beside rope bridges leading to zeppelin mooring towers. Deckhands and rookies about to step onto their first high-wind walkway often buy this brew right before boarding. Bottles are loosely tied with twine and stamped with a feather mark.
Typical Cost: 6 to 8 Silver per vial
Glider School Training Sheds on Wind-Run Cliffs
Flight instructors offer it to new gliders as a “confidence sip” before first launch. It is not advertised as magical—just recommended for anyone who grips the wings too tightly. Brew is poured into tin cups rather than packaged, consumed on site.
Typical Cost: 4 Silver, or included as part of training fee (credited as a “calming supplement” on the ledger)
Temple of the Sky Monks (High Platforms with Wind Chimes)
Sky monks who practice balance and wind-dancing rituals consider this brew a humble aid for those who have not yet learned to feel the wind in their bones. Sold wrapped in white cloth, always with a spoken reminder: “Drink only if you intend to breathe with it.”
Expected Donation: 5 to 9 Silver, though devout pilgrims may offer incense or prayer strips instead of coin
Ropewalker Guild Outposts atop Trade Rigs
Used by professional rope-runners who ferry messages across high bridges between cargo towers. Their guilds stock the brew in sealed leather skins kept cool in breeze frames. Novices buy it before first shift to avoid losing balance when the bridge sways.
Typical Cost: 1 Gold per tightly sealed skin containing two doses, or exchanged for rope oil or harness repair tokens
Stormship Crew Stalls in High-Tide Ports
Crew captains purchase crates of it to issue to deckhands before moving through storm corridors. The brew is considered part of “safety rations,” consumed prior to deployment on upper rigging or lookout masts. Dockside quartermasters sell in bulk.
Typical Cost: 1 Gold 5 Silver per bundle of four vials, or deducted from crew wages as a “wind hazard supply fee”
Black-Market Cliff Sellers (Wind-Smugglers)
Hidden sellers perch on narrow ledges along smuggler air routes, offering a stronger, harsher taste version that helps dodge aerial patrols without being knocked from glider rails. Payment is often not coin, but navigation tips or stolen draft maps.
Typical Cost: 2 Gold per dose or traded for air-route charts, forged cargo manifests, or glide-silk patches
Festival Wind Races and Balloon Rally Camps
During seasonal wind festivals, balloon teams and amateur gliders buy this brew like good-luck charms. Sold from bright stalls decorated with wind ribbons, often branded with exaggerated claims like “Makes you part bird!”
Typical Cost: 8 Silver to 1 Gold, often comes with a colored ribbon tied around the wrist to “remember the wind”
Roleplay in different environments:
Zeppelin Dock or Airship Launch Platform
Defense — A novice crew member steps onto a swaying gangplank high above the sea. Panic rises as wind roars through cables. They drink the brew, breathe, and suddenly feel the wind’s movement instead of fearing it. Roleplay beats: their steps shift from stiff and reactive to light and flowing. They no longer fight the gusts—each sway is matched instead of resisted. This prevents falls, reduces panic, and allows them to navigate with unexpected grace, earning nods from seasoned crew.
Offense — A rival crew or boarder attempts to sabotage the airship. The brew’s user moves along rigging with wind-assisted precision, slipping past defenders or positioning themselves for a strike while others struggle against crosswinds. Their attack isn’t stronger, but it lands when opponents are off-balance due to wind pressure. The user uses airflow-cheating movement like a blade.
Wind-Cliff Glider School
Defense — Students struggle with takeoff jitters. A drink of the brew teaches them to angle their wings with the gust, not against it. Roleplay beats: instructing others calmly, demonstrating how to “feel the pull before the drop.” It protects new gliders from body-lock freezing during their first launch. Fear of wind becomes dialogue between body and breeze instead of a threat.
Offense — During mock racing duels or aerial tag challenges, a user times their dives with updrafts, slingshotting around another glider. They use the airflow to cut ahead, forcing others off their ideal lines. It’s not brute force sabotage—it’s mastery of air that becomes a competitive edge.
High-Rope Trade Bridges Between Cargo Towers
Defense — While crossing dangerous suspension bridges in high wind, the user moves as though tethered to the gusts themselves. Where others crouch and cling, the user flows. Roleplay beats: walking sideways into a gust instead of stepping back, guiding panicked allies by showing them how to shift stance with wind instead of against it. It shields from falls and makes the user a calm point of reference.
Offense — Under threat of ambush or pursuit, the user takes advantage of rope sway and wind push to suddenly accelerate or dodge. While enemies grab railings or stagger, the brew-user uses the momentary gust as a pivot point, spinning behind attackers or making them lunge into empty space.
Balloon Festival or Wind-Race Arena
Defense — A racer drinks before their heat begins. When a sudden gust catches their sail, they do not correct with force, they lean into it just enough to ride it cleanly. This protects their harness and glider from tearing under stress. Roleplay beats: spectators noticing their elegance rather than raw speed.
Offense — In the same setting, the user may shout or make a timed movement that causes their competitor to instinctively resist a gust rather than flow with it—causing disruption in their path. The user becomes a manipulative wind-dancer, using airflow as a tactical influence tool.
Stormship Expedition or Sky-Patrol Chase
Defense — Sky scouts use the brew during patrol to handle unpredictable gusts when riding the upper decks. When a crosswind hits during a turn, the user doesn’t stumble or crash into rigging—they pivot gracefully as though carried by invisible current. It reduces exhaustion and fall risks.
Offense — In a chase scenario, a user jumps from one rope ladder to another, catching the tailwind to swing across angles others can’t reach. They use the air itself as a vector weapon, appearing where foes don’t expect. In combat, they sidestep attacks by being “pulled” by gusts, confusing enemies who expect grounded footwork.
Smuggler Ledges and Clifftop Black Routes
Defense — When fleeing from patrols, a user with the draught drinks while hugging a cliff edge. They time their movements with passing air pressure, letting wind guide them along ridges and shelves. Where others slip, they drift.
Offense — The user may intentionally bait a pursuer into resisting a sudden crossdraft, while they themselves let it carry them sideways, causing the pursuer to overreach or slip. Wind becomes a misdirection blade.
Temple of the Wind Monks
Defense — Monks use the brew as a training pass for novices learning wind-walking meditation. It prevents freezing or missteps on narrow platforms. Roleplay beats: breathing lessons, feeling currents on the back of the neck, wind chimes responding in subtle resonance.
Offense — Advanced monks use the brew not for defense but for redirection—grabbing sleeves or redirecting momentum by stepping just at the moment a gust hits. They make opponents stumble without touching them directly—wind-assisted martial redirection.
Ethical and Social Consequences:
• Some pilots consider it acceptable training assistance; others say true wind-sense must be earned through hardship, not bottled.
• Using it in official glider trials is frowned upon in some regions—considered “cheating by wind’s grace.”
• Sky monks tolerate it but remind users: “Wind obeys no one. It merely agrees with those who do not argue.”
• Black-market smugglers prize it but often combine it with risk-taking bravado, leading to reckless stunts.
This brew is not flight—it is cooperation with air. Those who drink it either become part of the wind’s rhythm… or learn the hard way that pretending to understand the wind is not the same as listening to it.

Above is appearance of brew; below is reaction to brew.

Perception of Activation:
When the Slipstream Draught of Feathered Breath takes effect—typically at the moment the user moves with intention rather than tension—the following sensations manifest:
User’s Perspective (Internal Experience):
• Sight — Movement in the world seems outlined by invisible currents. Dust motes, loose fabric, and even hair strands appear to drift in meaningful patterns, revealing subtle directional flows the user had never noticed before. Edges of objects appear “lined” by imagined wind trails.
• Sound — A faint rushing whisper enters awareness, not loud, but ever-present, like distant air passing over a glider wing. Even in still air, the user hears the shape of where wind would be if it moved.
• Touch — Skin feels lightly brushed by shifting pressure, like the air itself is mapping the contours of the body. Limbs feel slightly drawn or suggested in certain directions, as if options for movement are gently “highlighted” by the breeze.
• Smell — A crisp, high-altitude scent like thin mountain air or distant rain flickers through the senses, regardless of location. To the user, everything smells a little cleaner, sharper—tension is replaced with alert clarity.
• Taste — A cool, mineral-laced tingle settles under the tongue, creating a awareness of breath and airflow through the throat. Breathing feels easier, lighter, as though the lungs are being guided by wind itself.
• Extra-Sensory — In the Mind’s Eye, faint spirals and arrows drift around pathways, railings, or open spaces, like the world is annotated with invisible wind runes. The user briefly feels as though they are a single feather suspended by unseen currents, able to shift direction with the slightest intent.
Observer’s Perspective (External View):
• Sight — The user’s movements become subtly smoother, as if their steps anticipate the sway of rope, plank, or platform before it shifts. They appear to move a heartbeat ahead of environmental motion. Clothing and hair might lift slightly even in places where the wind is still.
• Sound — Footfalls may sound lighter, almost muted, as though the user disperses impact through grace rather than weight. Movement might create gentle air murmurs, like cloth cutting clean lines through stillness.
• Presence — To observers, the user seems more placed in the environment, like they belong in moving air rather than fighting against it. This generates either admiration or unease, depending on whether the viewer respects windcraft.
• Extra-Sensory — Sensitive individuals perceive trailing lines of air following the user like faint contrails, curling off their shoulders and elbows with each shift in posture.
Positive Effects:
• Enhances graceful movement and protects against panic in high-wind or unstable footing scenarios.
• Allows subtle control over positioning and evasion through cooperation with airflow instead of brute balance.
• Encourages roleplay focused on breathing, subtle alignment, and “feeling the draft” before acting—a form of meditative mobility.
• Makes the user a calming presence during aerial or height-based hazards, often guiding others through example rather than command.
Negative Effects:
• Overconfidence risk—users may begin trusting airflow too much, leading to reckless leaps or glider stunts they are not trained for.
• Ground-bound observers or traditionalists may view the user as “unnaturally wind-touched,” causing suspicion or jealousy.
• Users heavily tied to earth, stone, or rigid stances may feel a disorienting detachment, as if the world beneath their feet is less secure.
• If a second dose is taken too soon, the user may feel disconnected from solid ground entirely, moving as if weightless and losing reliable traction.
The Slipstream Draught does not grant wind mastery—it invites the drinker to stop being an obstacle to the air and become a part of its dance.
Recipe Title: Slipstream Draught of Feathered Breath — Wind-Sense Infusion Method
Materials Needed:
• 1 flask of Sky-Condensed Dew (must be collected from surfaces exposed to open wind at a high elevation—dew gathered from still air is unusable)
• 3 slivers of Glidegrass Reed (a plant that naturally bends with breeze rather than breaking—often grows near cliff edges and glider launch sites)
• A pinch of Fine Feather-Dust (not from plucked feathers—must be dust shed naturally from birds in flight corridors or taken from wind-caught molting traps)
• 2 drops of Aether-Aer Resin (a translucent sap that forms on ropes and sails after repeated exposure to high winds and elemental air currents)
• Breath-Tether Salt (collected by leaving salt crystals in a wind channel overnight so they take on directional striations)
• Optional Finesse Additive: A single thread of glide-silk from a windrider’s harness or sailcloth scrap—never more than a strand, to prevent over-attunement
Tools Required:
• Lightweight open-lipped copper pan or suspended bowl (must allow wind or airflow to pass over the surface during brewing—you do not cover this potion during infusion)
• Stirring implement made of reed or hollow bone (solid metal disrupts airflow resonance)
• Breeze mesh or perforated cloth filter (designed to allow air to pass through during filtration rather than blocking it)
• Elevated or open-air brewing location ideally with at least a steady breeze—not to be brewed underground or in air-still workshops
• Optional: Direction chimes or windbells hanging nearby to harmonize ambient airflow during brewing
Skill Requirements:
• Basic alchemical brewing knowledge
• Ability to remain calm in windy or exposed environments without resisting instinctively (brewing this sheltered breaks the effect)
• Awareness of air current direction—brewer must face into the wind during infusion steps
• Optional Sky Monk or Glider Training: Knowledge of breath control to match stirring rhythm with gusts
Crafting Steps:
- Expose the Workspace to Air Movement:
Brewing must occur in an open area with detectable airflow. Hang windbells or light streamers nearby. If they do not move at least once every few breaths, wait or change location. - Prepare Sky-Condensed Dew Base:
Pour dew into the open-lipped copper pan. Do not heat directly. Instead, let natural warmth or gentle hand-warmed heat beneath the pan cause slow vapor swirling. Watch for faint air ripples forming over the surface. - Lay Glidegrass Reeds Gently:
Place reed slivers along the surface parallel to the wind’s direction. Do not stir yet—wait until the reeds visibly shift slightly under wind influence. This proves environmental attunement has begun. - Add Breath-Tether Salt:
Sprinkle the salt gently from above. The crystals should drift slightly before touching the surface. If they fall straight down without lateral motion, brewing is not aligned with wind. - Stir with Hollow Reed Implement:
Stir in long arcs that match the direction of passing gusts. If wind shifts mid-stir, let your hand follow it rather than forcing a fixed pattern. The mixture should create rippling lines instead of circular ripples. - Introduce Feather-Dust:
Scatter feather-dust from a height. Ideally, it should spiral or drift before touching the liquid. If it drops in clumps, swirl the air over the brew with your hand or stirrer to encourage upward draft. - Add Aether-Aer Resin Drops:
Touch the resin to the rim and allow it to run down naturally rather than dripping vertically. The resin should streak like a falling breeze, forming faint white trails. - Optional Silk Thread Finishing:
Drag a single glide-silk thread lightly across the surface without submerging it fully. Lift it away when the thread begins to tug gently—this indicates wind resonance. - Air-Filter Through Breeze Mesh:
Lift the pan and slowly pour the brew through the perforated cloth or mesh. Angle the pour to allow the wind itself to push the liquid through rather than gravity alone. If the wind catches some of the droplets, that is considered a blessing of slipstream. - Bottle Without Sealing Immediately:
Fill glass or light crystal vials but leave the stopper loose for several breaths so residual wind can “touch” the final product. Seal only when you feel a draft brush your fingers.
Feather That Refused to Fall
The oldest telling of the Slipstream Draught does not come from guild records or airship logs but from a nearly erased song etched in the wood of a broken glider wing found at the base of the Wind-Run Cliffs. The script is fractured, repaired through many translations, and begins with a phrase roughly formed as: “Not all who fall are falling.”
In the era when the sky docks were still being built and airships were experimental leviathans prone to tearing themselves apart, there lived an apprentice mechanic known only as Talla of the Bronze Feathers. She was not born a sky-walker. In one translation she is described as “the one with heavy steps,” and in another as “girl of the ground-heart who wished to hear the wind speak.” She worked among cargo pulleys, never allowed on the upper rigging because, as her overseer said, “You fight the wind—you do not follow it.”
One day, Talla saw a senior glider master walk along a rope-line in a storm without gripping it once. He moved not against the wind but with it, body bending in invisible rhythm. She asked for his secret. He laughed and said in a line now fragmented: “Wind does not need conquering. It needs conversation.”
The fragments claim Talla left her post and climbed the cliffside alone, carrying only reed stems, dew bottles, and scrap resin from damaged airship sails. She built no grand lab—only set her tools in the open air and let the wind topple them until she learned to work with its push. Many versions say she failed, was blown down, climbed again—over and over until her hands bled and her braid tore loose.
Then, one dawn, when the rising draft kissed her tools instead of scattering them, she brewed the first Slipstream Draught. Witnesses—if they ever truly existed—say she drank it not as a triumph, but as a question to the sky. After that, her steps changed. She walked rope-lines without looking down. She moved along airship hulls as though weightless—not by flight, but by perfect acceptance of the wind’s invitation.
Jealous mechanics mocked her, calling it wind-witch’s luck. One challenged her to a wind duel—a race across the high tension cables during a storm front. He wore iron cleats and fought for balance. She drank a reed vial of her brew and listened. Where he grappled with the wind like an enemy, she let it pull her, dip her, lift her. The song says he screamed, “The wind betrays me!” and she whispered, “The wind betrays no one—you betrayed the wind.” He fell, caught by nets and rope hooks, shamed by his own rigidity.
Talla, it is said, walked the full length without one hand touching rope.
Later lines repeat faintly: “She did not fly. She simply did not fall.”
Some believe Talla left no grave because she never stopped walking—following wind currents from cliff to cliff, her bronze feather tokens left tied to airship ropes as quiet blessings. Air sailors still tie small copper feathers to rig lines in her honor, muttering poorly remembered words: “Let the wind go first.”
Moral of the Story: The air does not carry those who struggle against it. It carries those who learn how to be light.

Effects:
• Flow with Air: You have Advantage on tests to balance, avoid being blown off course, leap to or from moving surfaces, or ride a rope/line in wind.
• Gust Pivot (1x): After failing a movement-related test (falling, slipping, missing a jump), immediately describe a wind-aided adjustment and reroll using a different relevant attribute; the second result stands.
• Light Landing: Once during the duration, treat a short fall as one step less severe (Judge’s scale) and avoid being knocked prone if you succeed on a quick DEX test.
Backlash: If more than one dose is taken before resting, Save vs WIS or suffer Disadvantage on checks requiring planted, stubborn force (bracing, wrestling, dead-lifts) for the next turn/watch as your stance keeps “giving” to the air.
Fate
Name: Slipstream Draught
Type: Consumable Asset
Effect: Upon drinking, gain the temporary Aspect “Moves Like Wind Over Rope” with one free invoke. This Aspect can be invoked to gain a bonus when performing agile movement in high-wind, unstable footing, gliding, leaping between shifting structures, or evading while in motion. Once during the scene, after failing a mobility-related action but before consequences apply, you may invoke this Aspect to narrate a wind-assisted adjustment and reroll.
Compel Option: The GM may compel this Aspect to cause the user to overtrust the wind, leading to overly light footing or drifting where firm stance is needed, resulting in mispositioning or missed grounding opportunities.
Numenera & Cypher System
Name: Slipstream Infusion
Level: 1 Cypher (Anoetic)
Form: Liquid Brew
Duration: 1 hour
Effect: Gain an Asset on tasks involving balance, movement through wind, gliding, riding momentum, or reacting to swaying or speeding terrain. Once during the duration, after failing a movement task or Speed Defense roll tied to motion or wind, the user may immediately switch to a new approach (like turning a jump into a roll or dive) and reroll with the same Difficulty.
Extra Sense: Once during the effect, the user may ask the GM for a hint such as “Which direction of movement would let me cooperate with the airflow here?” and receive a brief directional cue.
Overuse: Drinking a second before resting forces a Speed Defense roll (Difficulty 2) to avoid gaining an Inability on tasks requiring firm, rooted stances for ten minutes due to overlightened balance.
Pathfinder (latest edition)
Name: Slipstream Brew
Consumable, Common, Level 1
Activate: Drink (Interact)
Duration: 1 hour (or extended if the user continues to actively harmonize with wind through observed roleplay)
Effect:
• You gain a +1 item bonus to Acrobatics checks made to Balance, Maneuver in Flight (if applicable), or Traverse Narrow Surfaces in windy or unstable conditions.
• Slipstream Step (1x): After failing an Acrobatics check or Reflex-based saving throw caused by wind, sway, or hazardous movement, but before results are finalized, you may immediately attempt a new check using a different action approach (such as Tumble Through or Grab an Edge) to represent a wind-guided pivot. The new result replaces the old.
• Feathered Descent: Once during the brew’s effect, reduce falling damage by 5 and land on your feet if you succeed at a DC 10 Acrobatics check to control your posture.
Backlash: Drinking a second brew before daily preparations forces a DC 12 Will save or suffer a –1 penalty to Athletics checks for climbing or bracing for 10 minutes due to overly fluid stance.
Savage Worlds
Name: Slipstream Draught
Type: Alchemical Consumable
Duration: 1 hour or one high-movement scene
Effect:
• Gain +1 to Agility-based rolls involving balance, leaping, avoiding wind push, or performing movement on unstable or speeding ground.
• Wind Pivot (1x): After failing a Trait roll tied to movement or evasion, the user may declare a wind-guided correction and immediately reroll using a different Attribute (for example, using Smarts to read wind flow instead of raw Agility). The second roll replaces the first.
• Feather Step: Once during the effect, the user gains +1 to a Spirit roll to resist being Shaken by sudden impact or fall-based shock.
Overuse: If a second dose is taken before rest, the user must make a Spirit roll. On failure, they suffer the Distracted condition for 1d6 minutes when attempting actions that require heavy footing or brute stability, feeling too “light” to anchor properly.
Shadowrun
Name: Slipstream Draught
Type: Alchemical Ingestible (Common Glide Formula)
Duration: 1 hour
Effect: Gain +1 dice to Gymnastics or Reaction-based tests involving movement across unstable surfaces, jumping from moving platforms, glider rigging work, or evading while in windy or high-speed conditions. Once during this duration, after failing such a test, the user may declare a Wind-Shift Adjustment and reroll using a different relevant skill (such as replacing Gymnastics with Pilot (Aircraft) or Free-Fall to represent wind-guided correction). The second roll stands.
Feathered Balance: The first time during the duration that the user would suffer a dice pool penalty from wind, sway, or poor footing, ignore that penalty.
Overuse: Taking a second dose before the first ends requires a Body + Reaction (Threshold 2) test. On failure, the user suffers –1 dice on Strength-based mobility actions for 10 minutes due to over-light footing and poor anchoring.
Starfinder
Name: Slipstream Elixir
Type: Consumable (Hybrid Wind-Attunement Brew), Level 1, Common
Activation: Drink (Standard Action)
Duration: 1 hour or longer with active wind-responsive movement roleplay
Effect: Gain a +1 insight bonus to Acrobatics and Piloting checks made to move across shifting surfaces, glide, or maintain control in high-wind or moving-platform conditions. Once during the effect, when failing a Reflex save or mobility-based skill check tied to wind or unstable footing, the user may immediately reroll using a different appropriate skill (e.g., switching from Acrobatics to Piloting to ride the wind’s flow).
Wind Harmony: Once, gain a +1 bonus to a Fortitude or Will save made to avoid being knocked prone or disoriented by sudden gusts or motion shifts.
Overuse: Consuming a second elixir before resting requires a Fortitude Save (DC 12). On a failure, the user takes a –1 penalty to Athletics checks for 10 minutes, finding solid grounding harder due to a lingering “light-step” sensation.
Traveller
Name: Slipstream Brew
Type: Chemical Consumable (Common Sky-Route Stock)
Duration: 1 hour
Effect: The drinker gains DM+1 to Athletics (Dexterity), Flyer, or Vacc Suit checks involving movement across sway, wind-affected surfaces, or reacting to sudden motion. Once during the duration, after failing such a check, they may immediately apply a different Skill roll (such as using Flyer instead of Athletics) to represent adjusting to airflow. The second result applies.
Controlled Descent: The user gains DM+1 to the next roll to reduce damage or recover footing after a fall or forced movement while this brew is active.
Overuse: Taking another dose before resting requires an END (8+) roll. On failure, suffer –1 DM on melee or forceful physical actions for 1d6 minutes due to overreliance on flowing movement rather than physical bracing.
Warhammer (Fantasy or 40K-style)
Name: Slipstream Draught
Type: Brewed Tonic, Common
Duration: 1 hour
Effect: Gain +10 to Agility Tests involving wind, ropework, gliding, or moving atop unstable or speeding surfaces. Once during the duration, after failing such a Test but before the GM declares the consequence, the user may attempt a new Test using a different Skill or Lore reflecting wind-guided adjustment—like substituting Acrobatics-style grace for a Climb roll. The second roll replaces the first.
Feather Footing: Once, gain +10 to a Toughness or Willpower Test made to avoid being knocked prone or disoriented by wind or motion shock.
Backlash: If a second draught is taken before the first ends, make a Willpower Test. On failure, suffer –10 to Strength-based Tests for 1d10 minutes due to an inability to properly root stance, the body still trying to “flow” instead of brace.
