Boulder Bash

Form a boulder of unworked earth, rock, and stone, creating a 10x10 foot square of difficult terrain within 90 feet of you.

You hurl this boulder at a point within 90 feet, detonating it in a 5 foot radius. All creatures within the radius must make a Dexterity Saving Throw.

On a fail, the target take 3d8 bludgeoning damage is knocked prone. On a success, the target takes half damage as the boulder shatters and is not knocked prone.

When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
