Vescavors yammer the endless chorus of the Abyss. Any creature within 15 feet of a vescavor swarm or inside it must succeed at a DC 15 Will save or be confused for 1 round. This is a mind-affecting compulsion insanity effect. A creature that saves cannot be affected by the same vescavor swarm's gibbering for 24 hours. The save DC is Constitution-based.
Vescavors can devour nearly anything, with the exception of adamantine. If the swarm attacks an object or structure, the vescavors ignore its hardness if it is made of any substance other than adamantine. Additionally, every round that a creature is in the same space as the swarm, the vescavors begin devouring one object on the creature. The object takes half its maximum hit points in damage and gains the broken condition. If the vescavors attack an object with the broken condition, it is destroyed. An attended or magic object can make a DC 15 Reflex save to negate this effect. The save DC is Constitution-based.
Vescavors embody the meanest depravities of the Outer Rifts, and walking among them is akin to being trapped in the Abyss itself. Any creature that spends more than 3 rounds inside a vescavor swarm must succeed at a DC 13 Will save or gain a type of madness.
Roll on the Types of Insanity table to determine which type of insanity affects the creature—the creature does not make another Will save against the specific insanity. This affliction is permanent, but can be healed as detailed in the Curing Insanity section of the Sanity and Madness rules. The save DC is Charisma-based.
