Stench

This spell creates a sickly stinking smell of rot and decay that emanates from the caster's body. The stench duplicates the sickening effect of ghasts (see its entry in the Basic Fantasy Field Guide Omnibus). The smell of death and corruption surrounding the caster is so overwhelming that living creatures within 10 feet must succeed a save vs. Poison or be sickened for 2d6 rounds (-2 to attack rolls). For every three levels the caster has, a penalty of -1 on the save is applied to those affected (at 3rd the save is at -1, at 6th level at -2, at 9th level at -3, etc). A creature that successfully saves cannot be affected again by this spell or a ghast’s stench for 24 hours. A neutralize poison spell removes the effect from a sickened creature.
