Combat

Rug rats seek to climb up from the rug they're in and attack any warm-blooded prey they encounter. A rug rat swarm deals 1d6 points of damage to any creature whose space it occupies at the end of its move, 2d6 if they stand upon the rug they inhabit.

Disease (Ex): Filth fever—swarm attack, Fortitude DC 14, incubation period 1d3 days, damage 1d3 Dex and 1d3 Con. The save DC is Constitution-based.

Distraction (Ex): Any living creature that begins its turn with a rug rat swarm in its square must succeed on a DC 14 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.

Meld with Fabric (Su): A rug rat swam can meld with the rug it inhabits. This makes them unable to be attacked, though the rug can still be destroyed. If the rug is destroyed, they immediately meld back into their rat forms and scatter, at which point they are treated as normal rats.

Skills: A rug rat swarm has a +4 racial bonus on Hide and Move Silently checks, and a +8 racial bonus on Balance, Climb, and Swim checks. A rug rat swarm can always choose to take 10 on all Climb checks, even if rushed or threatened. A rug rat swarm uses its Dexterity modifier instead of its Strength modifier for Climb and Swim checks. A rug rat swarm has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard.
