Ability
Stifle
Circumstance: Trigger: A creature in the swarm's space attempts to Cast a Spell
The swarming hands clamp over the triggering creature's mouth, preventing it from vocalizing. The affected creature must succeed at a DC 22 Reflex save or the triggering action is disrupted.
Trait
Swarm
A swarm is a mass or cloud of creatures that functions as one monster. Its size entry gives the size of the entire mass, though for most swarms the individual creatures that make up that mass are Tiny. A swarm can occupy the same space as other creatures, and must do so in order to use its damaging action. A swarm typically has weakness to effects that deal damage over an area (like area spells and splash weapons). Swarms are immune to the grappled, prone, and restrained conditions.
Trait
Undead
Once living, these creatures were infused after death with negative energy and soul-corrupting evil magic. When reduced to 0 Hit Points, an undead creature is destroyed. Undead creatures are damaged by positive energy, are healed by negative energy, and don't benefit from healing effects.
