Exhume

For just a moment you animate a fallen foe to strike from the grave. Choose a corpse you can see who has died in the last 10 minutes or an undead creature you control within range. That corpse or undead creature makes one attack with a melee weapon they have against a creature you choose within 5 feet of them. If the target of this spell was a corpse, this attack uses the statistics of the creature when it was alive. If the corpse is lying on the ground, they have disadvantage on these attack roles. After a corpse makes all its attacks, it reverts to its lifeless form.

The number of attacks this spell causes a corpse or undead creature to make increases by one when you reach 5th level (two attacks), 11th level (three attacks), and 17th level (four attacks).
