Ghast

The ghast is similar to the ghoul, but is distinguished by its monstrously foul and supernaturally nauseating stench. It is also more powerful than a standard ghoul; even elves can fall victim to a ghast's paralytic touch. It resembles very closely its undead cousins, but is far more deadly and cunning. Like ghouls, ghasts speak whatever language they did in life (usually Common).
