Giant Rat
About
Giant rats thrive beneath granaries, sewers and abandoned streets. A single rat tests a target from hiding; a pack closes only when blood or weakness gives it courage.

Traits

Special Attack
Filthy Bite: piercing, melee 5 ft, +1 to hit, 1d4+1. A wounded target makes a Tough save after the encounter; a failed save brings fever and weariness the following morning until treated or rested safely for a full day.
Special Defense
Pack Nerve: while three or more giant rats remain together, they gain +1 to attack rolls. Fire or the death of half the pack forces each survivor to make a Mind save or flee.
