Touch of the Graveborn

8-level Necromancy

Your hand grows numb and emanates the chill of the grave. Make a melee spell attack. On hit, you channel negative energy that disrupts the life force of living creatures, dealing 10d6 necrotic damage. In addition, an undead creature you touch takes no damage, but it must make a successful Wisdom saving throw or be controlled by you (as if you had created it by casting create undead) for the duration. You can’t control more than one undead creature in this fashion.
