Ghoul

Ghouls: These undead carrion eaters haunt the graveyards and battlefields that bore them, still bearing the rotting flesh they once wore in life.

A ghoul the usual undead immunities to critical hits, death magic, disease, level drain, ability drain, mind-affecting spells, paralysis, poison, and sneak attack.

The ghoul's creature weapons have on-hit effects; the two claw attacks inflict ghoul rot, while the bite stuns.
