Initiation Time: 1 action
Range: 60 feet
Duration: Instantaneous
You conjure up a wave of earth and stone that crashes down on an area within range. The area can be up to 30 feet long, up to 10 feet wide, and up to 10 feet tall. Each creature in that area must make a Strength saving throw. On a failure, a creature takes 5d8 bludgeoning damage and is knocked prone. On a success, a creature takes half as much damage and isn't knocked prone.
At Higher Levels. When you initiate this form at a higher level, the range of the form increases by 10 feet, the length, width, and height of the wave increase by 5 feet, and the damage increases by 1d8 for each level above 3rd.
