Stench (Ex): A giant cockroach secretes oily chemicals that nearly every form of animal life finds offensive. Every creature (except cockroaches) within 30 feet of the giant cockroach must make a DC 15 Fortitude save or be nauseated for 1d4 rounds. Whether or not the save is successful, the creature cannot be affected again by any giant cockroach's stench for 1 hour. The save DC is Constitution-based.
Tremorsense (Ex): A giant cockroach can automatically sense the location of any creature or object within 60 feet that is in contact with the ground.
Skills: A giant cockroach receives a +12 racial bonus on Climb checks. (This value includes the racial bonus for a natural climb speed.) It can always choose to take 10 on Climb checks even if rushed or threatened. A giant cockroach also receives a +10 racial bonus on Hide checks and a +6 racial bonus on Move Silently checks
Giant cockroaches are far more aggressive than their normal-sized cousins, belligerently attacking almost anything that moves.
