CS3: Irritant

Potion (chemosol), common

These pressurized chemical irritants can be sprayed on a creature as a ranged weapon attack (range 20 feet), causing the target’s flesh to break out into a painful blistering rash. The target takes 1d6 points of acid damage, plus 1 additional point of acid damage per round until the target can treat the inflammation, which requires any effect that heals damage or spending an action to make a successful DC 10 Wisdom (Medicine) skill check.
