Undead Curse

You look upon a humanoid and curse them with undeath. If a creature fails a Consitution Saving Throw, when the creature dies, it will rise during its next turn as a zombie, or skeleton if it's flesh is gone. You do not have control over this creature.

This curse can be removed with the Remove Curse or Wish spell.

At Higher Level: When you cast this spell using a spell slot of 4th Level or higher, you can target one additional creature for each slot level above 3rd. The creatures must be within 30 feet of each other when you target them.
