Earth's Response

You teleport to an unoccupied space within range. After you disappear, large rocks fall from above where you were before in a 10 feet radius. Creatures in the area must make a Strength Saving Throw or be knocked prone, taking 3d10 Bludgeoning Damage on a failed saving throw, or half as much on a successful one. The area is difficult terrain for 1d4 rounds.

When cast using a spell slot of 4th level or higher, the damage increases by 1d10 and the teleportation range increases by 10 feet for each spell slot above 3rd.
