Stench (aura, olfactory) 10 feet. A creature entering the aura or starting its turn in the aura must succeed at a DC 16 Fortitude save or become sickened 1 (plus slowed 1 as long as it's sickened on a critical failure). While within the aura, the creature takes a –2 circumstance penalty to saves against disease and to recover from the sickened condition. A creature that succeeds at its save is temporarily immune for 1 minute.
