You can cast this spell only at night. Choose up to three M or S Humanoid corpses within range. Each one becomes a Ghoul under your control. As a Bonus Action, if the creature is within 120 ft, you can mentally command them. If you issue no commands, the creature takes the Dodge action and moves only to avoid harm. Once given an order, the creature continues to follow the order until its task is complete. The creature is under your control for 24 hours, after which it stops obeying commands. This use of the spell reasserts your control over up to 3 creatures you have animated with this spell rather than animating new ones.
If you use a level 7 spell slot, you can animate or reassert control over four Ghouls. If you use a level 8 spell slot, you can animate or reassert control over five Ghouls or two Ghasts or Wights. If you use a level 9 spell slot, you can animate or reassert control over six Ghouls, three Ghasts or Wights, or two Mummies. See the Monster Manual for these stat blocks.
