Blood Puppetry

One creature of medium size or smaller you can see within range must succeed on a constitution saving throw. On a failure, you assume control of their physical body. On their turn, they must move according to your commands. You may also cause the creature to make a single physical attack with their action. At the end of each turn, the creature attempts a new saving throw. Whenever the creature succeeds on a saving throw against this spell, they take 4d8 necrotic damage and are freed from your control.
