Acid (Su): A sheet ghoul's breath weapon is a fine spray of powerful stomach acid that inflicts 1d8+1 points of damage, or half that with a successful Reflex save (DC 14). The acid stream has a range of 10 feet and can target only a single victim. A ghoul can spray acid in melee combat, but it cannot use its bite attack if it uses the acid spray. Spraying acid is a ranged attack, so using this ability in melee combat provokes attacks of opportunity.

Sheet ghouls rend with their claws and bite with their sharp teeth.

Sheet ghouls are almost always encountered singly. They are shunned by normal ghouls and ghasts, who attempt to drive sheet ghouls away whenever they are encountered. This might simply be out of fear, but it probably also has something to do with the fact that a sheet ghoul cannot "propagate" its species the way ghouls and ghasts can. Since both ghouls and ghasts are often found running in packs, they have no use for an undead creature that is unable to expand the pack's own numbers.

A sheet phantom can merge with the body of any humanoid it slays. The process takes about 12 hours, after which time the victim and sheet phantom transform into a sheet ghoul.

A sheet ghoul is the result of a sheet phantom merging with its humanoid victim. It looks like a normal ghoul, but closer inspection might reveal wispy strands of white material clinging to its face like cobwebs or a decaying shroud. This is the remains of the sheet phantom's linen form.

Sheet ghouls devour carrion and freshly killed prey.
