Stench (aura, olfactory) 30 feet. A creature entering the aura or starting its turn in the aura must succeed at a DC 30 Fortitude save or become sickened 1 (plus slowed 1 for as long as itʼs sickened on a critical failure). While within the aura, affected creatures take 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.
