Stench (aura, olfactory) 30 feet. A creature that enters the area must attempt a DC 16 Fortitude save. On a failure, the creature is sickened 1, and on a critical failure, the creature also takes a –5-foot status penalty to its Speeds for 1 round. While within the aura, the creature takes a –2 circumstance penalty to saves to recover from the sickened condition. A creature that succeeds at its save is temporarily immune to all xulgaths' stenches for 1 minute.

Stench Suppression [F] A xulgath skulker can suppress its stench aura as a free action to better hide its presence. The skulker can resume its stench aura as a free action.
