Ventriloquist

You can cast Ventriloquist on a target that was hit by a Blood Weapon in the previous turn. The target must succeed on a Constitution saving throw or become magically Influenced by you through the control of their blood. You can use your turn to move and take actions as the target. The target can make a Constitution saving throw at the end of each of its turns. On a success, the spell ends. Obviously self-destructive orders are not carried out. This spell fails on targets that don't have blood.

At Higher Levels. When you cast this spell using a 4th-level spell slot, the duration is concentration, up to 10 minutes.
