Monster Manual 5.5e
Ghouls rise from the bodies of cannibals and villains with depraved hungers. They form packs out of shared voracity.
Ghouls
Eaters of the Dead
Habitat: Swamp, Underdark, Urban; Treasure: Any
Packs of ghouls haunt the rotten corners of the world, ravenously hunting for corpses and those soon to be corpses. These gaunt, animate cadavers with unnaturally long tongues dwell in catacombs and ruins where they devour the contents of graves and paralyze foes with vicious claws.
Invocation of Doresain, King of Ghouls
On a plain of teeth, in a temple of filth, the starving king wastes no morsel. Every coffin a banquet. Every slab a platter. Now is the time of feasting!
