Using a corpse or bones of a dead Medium or Small Humanoid, create a Ghoul (level 6), Ghast or Shadow (level 7), Wight (level 8), or Mummy (level 9). The undead obeys your verbal commands and acts on your turn. You can have up to three undead created this way. If you create a fourth, the oldest one is destroyed.
