Earth Bolt

With a shout, you touch the ground at your feet and create a bolt of geomantic force that travels 20 feet long and 5 feet wide through the earth, causing the earth, rock, or sand to fly into the air, striking creatures along its path. Each creature in the line must make a Dexterity saving throw. On a failed save, a creature takes 6d6 bludgeoning damage and is thrown 10 feet backward. If the creature is Large or smaller it lands prone when thrown. On a successful save it takes half as much damage and isn’t thrown.
