Swarm, Rat

CR 2.00 Animal N Tiny HD 3
A squirming, roiling mass of squeaking rats draws closer, teeth flashing and claws scratching everything in its path.

A rat swarm typically consists of a biting, roiling mass of hundreds of disease-ridden rats driven to uncharacteristic heights of aggression by fantastic and overwhelming hunger. In such numbers, they become voracious hunters, capable of killing a full-grown human with hundreds of bites. Rat swarms are often found in the sewers of large human settlements.

Rat swarms surround and attack any warm-blooded prey in their path.

Universal Monster Rules

Disease (swarm) Ex from Universal Monster Rule
A creature with this ability causes disease in those it contacts. The effects of the disease, including its save, frequency, and cure, are included in the creature's description. The saving throw to negate the disease is usually a Fort save (DC 10 + 1/2 the infecting creature's racial HD + the creature's Con modifier; the exact DC is given in the creature's descriptive text). Disease can be removed through remove disease and similar effects.
Distraction (DC 12) Ex from Universal Monster Rule
A creature with this ability can nauseate the creatures that it damages. Any living creature that takes damage from a creature with the distraction ability is nauseated for 1 round; a Fortitude save (DC 10 + the 1/2 creature's HD + the creature's Con modifier) negates the effect.
