Earthbolt

With a shout, you strike the ground at your feet and create a bolt of seismic force that causes earth, rock, and sand to fly into the air, striking creatures along its path. Any creatures caught in the spell’s area take 8d6 bludgeoning damage. This spell functions only if you are standing on dirt, clay, sand, or stone (including stone floors), not on wooden floors or other surfaces. 

At Higher Levels: When you cast this spell with a spell slot of 4th level or higher, you deal an additional 2d6 bludgeoning damage.
