A spirit distilled from hallucinogenic mushrooms by a company started by Tobias Deuterium, the effects of the spirit are determined by a constitution saving throw, and how much they drink. It always gives advantage on charisma checks, and grants the person who drinks it Truesight for up to 1 hour due to the nature of the mushrooms used in its creation.

On a natural one the creature that drinks the spirit suffers from disadvantage on perception checks, attack rolls, insight checks, intelligence checks until next long rest. The creature also gains a form of indefinite madness.

On a natural 20 the creature suffers no negative effects from the spirit.

A creature may build tolerance to the effects from the spirit through repeated consumption over the course of a few days, in which case they are no longer affected by the spirit.

creatures immune to poison are unaffected by the spirit.
