Sheath of Poisons (5e Equipment)

Wondrous Item, uncommon This sheath was created by fencing alchemists, for quickly deployment of their substances. This sheat when found acomodates a specific type of one-handed blade: dagger, rapier, longsword or scimitar. The sheath of poisons bears a compartment that connects to an extradimensional space that allows the sheath to hold up to six vials of poison, acid, alchemical fire, holy water and similar objects. As a Bonus Action, you can automatically coat a weapon stored in the sheath into the substance contained in one of those vials and draw the weapon, consuming that vial. Doing so will apply the effects of that substance on the next creature you hit within 1 minute after the weapon is drawn. A weapon stored in this sheath is protected from the effects of the substance used.
