Vampire's Thrall

If you killed a creature with Malicious Bite, you may touch the corpse of the recently deceased to bring them back as a Thrall, its movements bent by your will. As a bonus action each turn, you can give the Thrall an order like you would an Unseen Servant, and it can attack. Even more, the stats of the creature you killed are preserved, with a -2 to their Strength, Dexterity, and Constitution scores. If you give it no commands, the Thrall will stand dormant and be vulnerable to attacks.
