Bend Blood

You attempt to puppet the body of a creature that you can see within range by magically controlling its blood. The target must succeed on a Constitution saving throw or else become afflicted by this spell for the duration and be restrained until the start of its next turn. It repeats the saving throw at the end of each of its turns. On a success, it is no longer affected by the spell. 

At the start of each of an affected creature's turns, it must make a Strength saving throw. On a failed save, it is paralyzed until the start of its next turn. Alternatively, instead of making it paralyzed, you can choose to control its movement and make it use its action on that turn to attack either a target of your choice or itself. On a success, it is restrained until the start of its next turn and nothing else.

Until the spell ends, you can use an action on your turn to try to afflict a new target that you can see within range. The last target stops being affected by the spell, and the new target must make the initial saving throw.
