Greater Ghouls are a highly upgraded version of ghoul and can be found lurking on Labyrinth Level's 3 and 4 of Durlag's Tower.

When encountered, they are automatically hasted, do greater damage, and have a much higher Hit Point level than their weaker brethren. They attack with both claws, inflicting pierce damage; while a successful bite attack will nauseate the victim and hold them immobile, thereby allowing the Greater Ghoul to easily finish off it's prey.
