Unholy Land

You release pure dark energy at a point on the ground that you can see within range. Bones and claws rip through the ground in a 100-foot-radius centered on that point and they begin to pierce any enemies and impose very difficult terrain on the ground in that area.

Each target creature on the ground must make a Dexterity saving throw. On a failed save, the target takes 15d8 Piercing damage, 30d8 Necrotic damage and is knocked prone, or half as much piercing and no necrotic damage on a successful one. On Each enemy creature on the ground that is concentrating loses concentration.
