Animate Corpse

Choose a small or medium humanoid corpse within range. While you concentrate, you animate this body as a skeleton or zombie (depending on the corpse's condition). See the description in the Monsters Manual. As a bonus action, you can issue commands to the undead, which he then carries out on his own initiative. It will execute these commands until it receives another one or will do nothing if the given action cannot be executed. If the spell ends and the undead has not been destroyed in combat, it will drop to the ground again as a corpse.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can target one additional corpse for each slot level above 1st.
