Pollute Potion

Toxic Tincture

“The cruel genius of the spell is not that it kills. It is that the victim chooses to drink it willingly.”
— Cozen Kato, Imperial Alchemist
There are poisons that kill the body and curses that wound the soul, but Pollute Potion occupies a more intimate category of cruelty. It corrupts trust itself. The spell takes one of civilization’s oldest symbols of healing, aid, or preparation and transforms it into betrayal concealed behind glass.   Among necromancers and covert operatives, the spell is considered elegant precisely because of how little spectacle it requires. There is no black smoke, no withering rot spreading visibly through the liquid, no obvious magical distortion announcing danger. A corrupted potion looks perfect. It smells correct. It tastes unchanged. Even its magical signature remains intact unless examined with exceptional care. The victim does not realize anything is wrong until the moment the liquid should save them.   By then, it is too late.   Most arcane historians believe the spell emerged during periods of prolonged political conflict where assassination through ordinary means became increasingly difficult. Royal tasters could test for mundane toxins. Priests could cleanse conventional poisons. Magical wards could identify hostile enchantments placed directly upon a target. Pollute Potion bypassed these protections by exploiting a dangerous assumption common to nearly every culture. Beneficial magic is trusted instinctively.   The spell does not destroy the original enchantment within the liquid. Instead, it contaminates the magical structure itself, forcing the potion’s restorative or empowering energies into collapse at the moment of consumption. Some scholars describe this process as magical necrosis, where living enchantment decays inward while preserving its outward form.   The result is deeply feared among alchemists because it undermines confidence in consumable magic as a whole.   In wartime, rumors of corrupted healing draughts have caused soldiers to reject perfectly safe supplies. Mercenary companies have fractured after officers accused quartermasters of sabotage. Entire caravans carrying medicinal elixirs have been burned rather than risk uncertainty. The psychological damage inflicted by the spell often exceeds the physical harm itself.   Necromancers favor different forms of corruption depending on intent. Some use the spell for assassination, ensuring the victim suffers fatal necrotic collapse when desperately reaching for survival. Others prefer subtler outcomes. A poisoned condition introduced before a duel or negotiation can shift events without immediately revealing magical interference. Particularly vindictive casters delight in redirecting the potion’s beneficial effect toward another nearby creature, transforming healing into humiliation as the intended recipient weakens while an ally or bystander unexpectedly recovers.   This final variation has produced more than one infamous court scandal.   Detection remains notoriously difficult. The corrupted liquid retains its original magical aura so completely that inexperienced diviners often miss the contamination entirely. This has led to growing distrust between alchemists and academic wizards, with many potion makers arguing that theoretical arcanists rely too heavily on magical analysis instead of practical testing methods refined over centuries.   Certain traditions refuse to serve potions in opaque containers for this reason, believing visibility itself discourages magical tampering. Others insist on ritual tasting ceremonies before battle despite the spell’s ability to remain dormant until full consumption. A few paranoid rulers abandoned consumable magic altogether after surviving attempted corruption plots.   The material component, spoiled herbs steeped in vinegar, reflects the spell’s underlying philosophy. Life curdled into decay. Medicine turned against itself. Many practitioners intentionally use herbs associated with healing to deepen the symbolic inversion. Rotten sage, blackened mint, and mold covered lavender remain particularly common among ritualists who appreciate theatrical precision.   Though feared, the spell carries limitations that prevent it from becoming universally dominant. Divine consumables created directly through sacred intervention resist corruption entirely, as do liquids empowered by artifact grade magic or the highest circles of spellcraft. Most scholars interpret this immunity as evidence that truly transcendent magic possesses structural stability beyond the necromantic interference the spell relies upon.   Even so, Pollute Potion retains an ugly reputation unmatched by more openly destructive spells. Fireballs kill enemies. Curses torment rivals. This spell weaponizes care itself. It transforms the final hope carried on a wounded soldier’s belt or resting on a healer’s shelf into an instrument of deliberate malice.   That is why experienced adventurers often develop strange habits around potions. Some insist on brewing their own. Some refuse drinks offered by strangers. Some carry animals specifically trained to test consumables first. Others simply pray the liquid works when the moment comes.   Because once the seal is broken and the potion swallowed, faith is all that remains.

“A blade can miss. A curse can fail. But when a dying man reaches for healing, he never hesitates.”

Pollute Potion

5-level Necromancy

Casting Time: 1 action
Range/Area: 30 feet
Components: Verbal, Somatic, Material
Materials: a spoiled herb steeped in vinegar
Duration: Permanent until triggered
You target one potion, elixir, tonic, or other consumable magical liquid within range. If the item is unattended, it is automatically corrupted. If the item is being carried by a creature, that creature can make a Dexterity saving throw to prevent the spell from corrupting it.   A corrupted liquid appears normal in all respects, including taste, smell, texture, and magical aura. A creature casting identify on the liquid must succeed on an Intelligence (Arcana) check against your spell save DC to detect the corruption. On a failed check, the spell reveals only the liquid’s original magical properties.   When the corrupted liquid is consumed, its original magic produces no beneficial effects. The creature that consumed it instead suffers one of the following effects of your choice when you cast the spell:
  • The creature takes 6d6 necrotic damage.
  • The creature is poisoned for 1 hour.
  • The creature can’t regain hit points for 1 minute.
  • The creature has disadvantage on attack rolls and ability checks for 1 minute.
  • The liquid’s original effects instead target a random creature within 30 feet of the consumer, if applicable.
  • Once the corruption is triggered, the spell ends.

  • Consumable magic created by artifacts, divine beings, or 9th-level magic is immune to this spell.
    At higher levels: When you cast this spell using a spell slot of 7th level or higher, you can target one additional consumable magical liquid for every two slot levels above 5th.
    Available for: Sorcerer, Warlock, Wizard
