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.
