Plaque Burst When killed, a tooth fairy swarm bursts into sticky, foul-smelling white dust. Each creature with 15 feet must succeed at a DC 20 Fortitude save or become sickened 1 (sickened 2 on a critical failure).

Speed 10 feet, fly 40 feet

Pinch [>] Tooth fairies pinch their victims' fingers, noses, ears, or similar protruding body parts. Each enemy in the swarm's space takes 2d6 bludgeoning damage (DC 20 basic Reflex save). Creatures that critically fail this save are sickened 1 from the pain.

Pry [>>>] The tooth fairies try to pry out one of their target's teeth. One enemy in the swarm's space takes 4d6 bludgeoning damage (DC 20 basic Reflex save). On a failed save, the target takes 2 persistent bleed damage and a –1 status penalty to Charisma-based skill checks, and they must succeed at a DC 5 flat check to Cast a Spell with a verbal component or the spell is disrupted. The penalty and spellcasting condition last for 1 day, or until the stolen tooth is returned and the target regains at least 1 Hit Point.
