Potion of poison

A potion of poison was an uncommon poison that mimicked a potion of healing.

Description
These concoctions looked, smelled, and tasted like healing potions or other beneficial potions. However, these were actually poisons masked by illusion magic. Using an identify spell revealed the true nature of these poisons.

Drinking them would inflict immediate poison damage to the imbiber and potentially poison them. The imbiber would take continuous poison damage, which could be lowered by a third of the original damage every six seconds if they were able to withstand it, until it reduced to zero.
