Blood Control

The blood mage forcibly controls a wounded target’s blood, making the target an ally of the caster for up to 1 minute.  The target must make a STR saving throw.  On a failed save the target is controlled by the will of the caster for up to 1 minute and must repeat the saving throw at the end of each of its turns.  If the target succeeds they resist (or break free from) the spell but still take 2d8 necrotic damage from the manipulation of its blood.  Creatures without blood are immune.

This spell scales at 6th level and again at 9th level allowing the addition of 1 target at each level.  (6th level 2 targets controlled and 9th level 3 targets)
