Blood Puppet

You bend the blood of an enemy in range and attempt to bring them under your command. The targeted enemy must make a Wisdom saving throw or will be enthralled by you until you dismiss the action. They retain their ability to speak and think, but their bodies are under your control to do as you wish. On a successful save, they take 2d6 necrotic damage. If an enemy is enthralled by you, they roll with disadvantage.
