These creatures are always searching for mortals who have powerful emotions and produce unbridled magic. They emerge from the world of faerie in places where the barrier between the two worlds is thin when they smell the sweet scent of delicious mortal failings and sorcery. They hunt for the chaos and emotion of mortals, and attempt to subdue them and drag them back into the faerie. There, the fear, love, and hatred mortals feel actually fertilizes disgusting fungal slimes on which they then feed and sell to other members of the fey for special favors.

When they appear, feasters appear as a human-sized maggot-like body with a distressingly humanoid face and two stubby clawed arms. Once every 3 rounds, a feaster can spew a spiritual fungal mass up to 30 feet, which explodes and coats all creatures within a 10-foot-radius burst with sticky filaments. Creatures other than feasters are entangled in the filaments and restrained if they fail a DEX check. An entangled creature can attempt to break free and end the condition with a successful CHA check.

Feasters can move into or out of the faerie as an Active action in areas where the barrier between the two worlds is weak such as a faerie ring or sacred grove.

The feaster projects an antimagic aura not unlike the spell.
