Poisons

Deadly poisons, venoms, inhalants and acids come in many forms. From commonly available weeds to rare and potent mixtures of monster secretions each one of these is a valuable tool in an assassin's kit.

In certain parts of the world where poison-immune people congregate, some of these may be used recreationally; most notably by naga and yuan-ti, who do not experience much effect from traditional drugs.

If the normal effects would apply the poisoned status, the poison-immune user experiences something like being drunk. For more specific effects, use a recreational analog to the effect - Coulabine's Lv4 Exhaustion provides a pleasant if somewhat overwhelming comfortable sleepiness.

Prices listed are for one dose unless otherwise noted. The dosage assumes weaponised use. For recreational use, it is typical to use a third of a dose.
