Crimson Puppet

(Activate Hemocraft must be active):

The mage enslaves a target, forcing it to fight alongside the party for a short time, after which the victim dies unless it has a higher CR than the caster's level. Creatures without blood are immune. As penance for invoking this spell, you will automatically take damage equal to 4d12 or expend 4 hit-dice.

Roll 10d10, and if the total number is more than that of the remaining HP of the target, they are immediately taken control of for the duration of the spell. As a bonus action, The dominated target is allowed to make its typical amount of melee/ranged attacks in a round at targets of the caster's choosing. Enemy targets within 30ft of the Crimson Puppet must succeed a Wisdom saving throw or also be frightened by the target for 1 minute. Targets can attempt to save again at the end of their turns. If not given any commands, the puppet will automatically take the "Dodge" action. If the dominated target dies while under the effect of the spell, it will detonate and force all creatures within 10ft of it to make a Dexterity saving throw. Upon a failed saving throw, targets will take an additional 4d6 bludgeoning damage, and only half if they succeed.
