Choose a creature you can see to make a Constitution save. If it fails, it takes 7d8 + 30 necrotic damage. If it passes, it takes half as much.

If the target dies and was a humanoid, it rises as a zombie permanently under your control at the beginning of your next turn. You can give it verbal orders that it will follow.
