SPECIAL ABILITIES

Blight (Su)

Plague swarms deal additional untyped damage equal to their standard swarm damage. This damage originates from divine power, similar to the spell flame strike. A plague swarm’s damage counts as magic and epic for the purposes of bypassing damage reduction.

Curse of Lycanthropy (Su)

A humanoid of any size who takes damage from a plague rat swarm must succeed at a DC 19 Fortitude save or it contracts lycanthropy and becomes a wererat. Any humanoid who contracts lycanthropy from a rat plague swarm becomes immune to bubonic plague.

Disease (Ex)

Bubonic Plague: Swarm—injury; save Fort DC 19; onset immediate; frequency 1/day; effect 1d4 Str damage, 1 Cha damage, and target is fatigued; cure 2 consecutive saves.

Hivemind (Su)

A plague rat swarm can maintain constant telepathic communication with every wererat it created with its curse of lycanthropy as long as they are on the same plane.

These wererats have an attitude of helpful toward the swarm.

Multiply (Ex)

Plague swarms spawn at an incredible rate. Once per minute, a plague swarm can produce a new swarm of the type listed in its stat block as full-round action. When the plague swarm is not in combat, it typically uses this ability once per minute. If the plague swarm is destroyed, all of the swarms that it spawned also disperse.

Reform (Su)

A rat plague swarm can be destroyed only if a mythic spellcaster (or a non-mythic spellcaster who succeeds at a DC 31 caster level check) affects it with remove disease on the round before the swarm is dispersed. This condition bypasses a swarm’s normal immunity to single-target effects.
