The noxious vapors and foul fluids that constantly weep and seethe from a hezrou's body are particularly heinous to those the creature grapples. Each round a creature is grappled by a hezrou, the grappled foe must make a DC 24 Fortitude save to avoid becoming nauseated. A creature nauseated in this manner remains nauseated until he succeeds on a DC 24 Fortitude save, or until a minute has passed during which he is not grappled by the hezrou, whichever condition comes first. The save DC is Constitution-based.
