Special Abilities

Death Cloud (Ex) When a scouring swarm dies, its component creatures decompose in 1 round, leaving behind freezing neon gas. At the end of this round, all creatures within 30 feet of the scouring swarm’s final position take 1d6 cold damage and gain the sickened condition for 1 minute. A successful DC 11 Fortitude save halves the damage and negates the sickened condition. Active environmental protections from armor protect against this sickened condition. Devour Organics (Ex) A scouring swarm’s swarm attack deals acid damage that harms only organic material. Entirely inorganic creatures are not harmed by a scouring swarm’s attack. The environmental protections of most light and heavy armor provide no defense against a scouring swarm, but powered armor with active environmental protections protects against a scouring swarm. A scouring swarm leaves no trace of organic material in any square it moves through. It can completely consume a Large or smaller corpse by spending 1d4 rounds in the corpse’s space, leaving behind only the creature’s inorganic gear. Vulnerable to Oxygen (Ex) A scouring swarm cannot survive in atmospheres that are at least 10% oxygen (this includes atmospheres that most species consider breathable, including thick, thin, and some toxic atmospheres). A scouring swarm in such an environment takes 1d6 damage at the beginning of each of its turns. In an atmosphere of 100% oxygen, this damage is doubled.
