Ghouls are undead monsters that have been raised to serve evil sorcerors. They are ravenous, drooling creatures that hunger for the flesh of the living. They attack with their bare hands and the touch of a Ghoul is cold enough to paralyze all but the strongest of heroes. The Ghoul does have the standard undead weaknesses to Fire and Harm and immunities to mental attacks and Ice.
Ghouls are found in the Temple of Fiends.
An exceptionally powerful variant of the Ghoul is called a Geist.
