Ghast

They resemble very closely their undead cousin, the ghoul, except perhaps being just a bit more slender and ghost-like. The stench of death and rot lingers around their undead forms.
Ghasts arealso far more deadly and cunning than ghouls, with their paralytic touch dangerously affecting their opponents.
They often lair with others of their own kind or act as the leaders of a group of normal ghouls.
