Special Abilities

 * Disease (Ex): Leng Ghoul Fever: Bite— injury; save Fort DC 22; onset immediate; effect 1d3 Con and 1d4 Dex damage; cure 2 consecutive saves. The save DC is Charisma-based. A humanoid that succumbs to Leng ghoul fever becomes a normal ghoul unless in life it had 12 or more Hit Dice, in which case it rises from death as a Leng ghoul.
 * Erudite (Ex): All Knowledge skills are class skills for Leng ghouls. In addition, a Leng ghoul can cast spells from any magic scroll as if it had the spells on its spell list. It automatically succeeds at the caster level check necessary to use the scroll.
 * Paralysis (Ex): A successful DC 22 Fortitude save negates a Leng ghoul's paralysis. At the end of each round after the first, the victim can attempt a new DC 22 Fortitude saving throw to end the paralysis effect; the effect is otherwise permanent. Once the effect ends, the victim is staggered for 1 round.
