From: Abyssal Shard
Lore: The Abyssal Infusion Oil is a potent concoction that draws its power from the dark energies of the Abyss. Legends speak of ancient alchemists who sought to harness the chaotic essence of the Abyssal Shard and combine it with rare and otherworldly ingredients to create a substance capable of overcoming resistances and inflicting chaotic damage. It is said that the oil’s creation was shrouded in mystery and danger, as it required venturing into treacherous and forbidden realms to acquire the necessary components.
Use: The Abyssal Infusion Oil is primarily used by warriors and adventurers who face foes with resistances to non-magical damage. When applied to weapons, the oil grants them the ability to bypass these resistances, making them effective against creatures that would normally shrug off such attacks. Additionally, the oil infuses the weapon with a touch of the chaotic energies of the Abyss, causing additional unpredictable and chaotic damage upon striking the target.
Tier 1 Stats:
- Bypass Resistance: Weapons coated with Abyssal Infusion Oil bypass resistances to non-magical damage, allowing them to deal full damage to creatures that would normally be resistant.
- Chaotic Damage: The chaotic energy infused in the weapon causes additional unpredictable damage, making it harder for foes to resist or mitigate the effects of the strike.
Skills:
- Weapon Proficiency: Characters proficient in the specific type of weapon coated with Abyssal Infusion Oil will have an advantage in utilizing the enhanced capabilities of the oil effectively.
Preparation: Creating Abyssal Infusion Oil requires careful alchemical processes and the combination of rare and exotic ingredients. The following components are needed for its preparation: Abyssal Shard (1), Voidvine Extract (a few drops), Netherfungus Spores (a pinch), Lunar Oils (a small vial), and Midnight Lotus Petals (2 petals). The Abyssal Shard acts as the catalyst, infusing the oil with the chaotic essence of the Abyss. The ingredients are mixed, heated, and processed to extract their potent properties and combine them into a powerful infusion.
Cost: Due to the rarity and the dangerous nature of the ingredients involved, Abyssal Infusion Oil is considered a valuable and sought-after substance. The cost of acquiring a vial of Abyssal Infusion Oil can vary depending on factors such as the availability of ingredients, the skill of the alchemist, and the demand in the market. As a rough estimate, a single vial of Abyssal Infusion Oil could cost around 100 to 200 gold pieces.

Usage and Environment: The Abyssal Infusion Oil finds its greatest utility in environments where creatures with resistances to non-magical damage pose a significant threat. Here are some examples of how the oil is used and the environments in which its effects come into play:
- Monster-infested Dungeons: In treacherous dungeons filled with monstrous creatures, adventurers often encounter foes with resistances to non-magical weapons. Coating their weapons with Abyssal Infusion Oil allows characters to overcome these resistances and deal full damage, enhancing their effectiveness against such creatures.
- Planar Crossroads: When venturing into planes or realms where denizens possess resistances to mundane attacks, Abyssal Infusion Oil becomes a valuable asset. Characters can utilize the oil to ensure their weapons remain effective in combating planar creatures, where the laws of reality and resistance vary significantly.
- Battlegrounds of Elemental Entities: When facing off against elemental beings or creatures infused with elemental energies, the Abyssal Infusion Oil proves invaluable. These creatures often have natural resistances to non-magical damage. By applying the oil to their weapons, characters can neutralize these resistances and strike their foes with full force.
- Quests Involving Resistant Foes: Characters may undertake specific quests or missions that involve enemies with resistance to non-magical attacks. The Abyssal Infusion Oil becomes a sought-after resource in these situations, allowing characters to gain an advantage and overcome the resistances, ensuring the success of their mission.
In these environments, characters carefully plan the usage of Abyssal Infusion Oil, applying it to their weapons before engaging in combat with foes possessing resistances. The oil allows them to bypass these resistances, deal full damage, and harness the chaotic power of the Abyss, adding an unpredictable element to their attacks.
Shard of Wailing Chaos
Long ago, when the heavens bled and the earth wept beneath a sky of shadowed flame, there came into being a shard torn from the heart of the Abyss. This shard, neither stone nor flesh, was said to pulse with the agony of countless realms devoured by chaos. The first mortal to uncover this shard was not a king nor a warrior, but an alchemist whose name has been swallowed by time, known only as The Seeker of Cries.
The Seeker wandered to the edge of the world, driven by whispers borne on winds that cut like glass. Upon finding the shard in a chasm lit by the fire of forgotten stars, the Seeker wept for the voices trapped within, each a tale of ruin and despair. Yet, as sorrow gave way to ambition, the Seeker sought to bind the shard’s chaos to mortal will, to forge from its despair a weapon against the cruel forces of resistance in the world.
Through trials of blood and fire, the Seeker mingled the shard’s essence with the breath of the Voidvine, the spores of Netherfungus, and petals stolen from the moon’s own flower. The concoction birthed was neither liquid nor smoke but a restless cascade of shifting light and shadow, which stilled only when held within a vial shaped from the Seeker’s own tears.
The first weapon anointed by this oil cleaved the very air as though angered by its own existence. It struck beasts clad in scales of impenetrable metal, pierced spirits bound by immortal oaths, and shattered curses older than time. Yet, each victory whispered back to the Seeker, not with triumph but with the agony of the shard’s origins—chaos unchained cannot be stilled.
The Seeker, it is said, vanished, consumed by the oil’s power, or perhaps devoured by the voices of the shard. Their works endured, however, for those bold enough to seek them. The oil became a coveted relic among adventurers, praised for its might yet feared for its unpredictable vengeance.
Moral: Chaos harnessed is chaos endured; wield not what seeks to wield you.
