Regurgitate 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 (1d6 per 2 levels acid), with a basic 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.
