Erupting Earth

Casting Time: 1 action
Range: 120 feet
Duration: Instantaneous
Choose a point you can see on the ground
within range. A fountain of churned earth and
stone erupts in a 20-foot cube centered on that
point. Each creature in that area must make a Dexterity saving throw. A creature takes 3d12 bludgeoning damage on a failed save, or half as
much damage on a successful one.
