Regurgitate Mutagen
Feat 4
Source Pathfinder Player Core 2
Requirements You are under the effects of a mutagen.
You redirect a mutagen within your body to spit a stream of stomach acid at a foe. A creature within 30 feet takes 1d6 acid damage for every 2 levels you have ((floor(@actor.level/2))d6 acid), with a reflex save against your class DC. On a failure, the creature is also Sickened 1 (or Sickened 2 on a critical failure). The mutagen's duration immediately ends.
