Everyone
Debuffed players move
to the edges of the room
Several players are pulled slightly before they're knocked back and given a dispellable debuff.
Debuffed players will drop a Latent Cultist puddle at their feet when the debuff ends or is dispelled.
Latent Cultists are ghostly images with a circle around them that float around the room as a form of area denial. Drop them at the edges.
