Earthshatter

The earth erupts in front of you, knocking creatures away and leaving behind a jagged wall of stone 10 feet high, 5 feet wide, and up to 60 feet long. The endpoints of this wall can be anywhere so long as some part of the wall is adjacent to you. For example, it could extend in a line straight in front of you, or form a wall horizontally with yourself at the midpoint. You may also make it a circle with a radius of 20 feet.

Creatures in the wall's area must make a Dexterity saving throw. They take 6d6 bludgeoning damage on a failed save, or half as much on a successful one. On a failed save, they also fall prone on a side of the wall that you choose.

When the spell ends, the stone wall crumbles to dust.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 3rd.
