Walking Corpse

From Diablo Wiki

Walking Corpses are Undead monsters found in Diablo III. These slow moving zombies are a bit larger than the base model zombie, and can presumably take a bit more punishment.

They are a very similar creature though, shambling around aimlessly, too stupid to use weapons or spells, only dangerous in large groups.

Walking corpses have a unique talent, in that upon death they sometimes break in half, but continue the battle as their upper bodies snap off and become a Crawling Torso. These bi-palegic monstrosities drag themselves after intruders, still intent on battle even without a leg to stand on.
