In addition, any human, humanoid, or demihuman creature it touches must make a successful saving throw vs. paralyzation with a -4 penalty or be paralyzed for 24 hours.
Characters slain by an elevated ghoul become standard ghouls thirty minutes after death unless a cleric casts bless on their remains.
(Note that elves are vulnerable to the paralysis effect, but do not become ghouls after death.)
A protection from evil spell keeps the creature at bay for 1 round.
