Animate Blood

This spell creates a blood clone of a creature that has just died. The target of this spell is the creature who died to provoke this as a reaction. When you cast this spell, the target becomes unable to be resurrected, and a blood copy of them is generated within 5ft of their body. The copy has the exact same stats and capabilities of the targeted creature, but also has half the spell slots that you have, rounded up, it also knows all of the spells that you know, it counts as undead, and any of its summoned and controlled creatures count as your summoned and controlled creatures and vice versa. You can only have one blood copy generated by this spell at a time, and you cannot cast this spell on a creature that is already an undead or a contruct.

On each of your turns, you can use a bonus action to mentally command any creature you made with this spell if the creature is within 60 feet of you. You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.

The copy dissipates when the spell ends.

Additionally, you may use a bonus action on your turn to touch a copy created by this spell and absorb it into you, giving you temporary hit points equal to half the HP it had left when you absorbed it, resetting and pausing the 24 hour duration timer on the copy, making the copy disappear, and making you able to resummon it with only a bonus action, getting rid of the temporary HP, but giving the resummoned copy double the amount of temp HP that you had when you resummoned it. It can telepathically communicate with you while inside of you. If you lose the temp HP without resummoning it, then the spell ends and the copy cannot be resummoned, effectively killing it.
