mudslide

4-level Transmutation

You slam both hands on the ground while facing your enemies, causing a mud wave to explode from the ground in a line that shoots towards them. The line travels 30 feet in the direction you are facing and has a width of 15 feet.   Each creature in the wave must make a Dexterity saving throw. A creature takes 4d6 bludgeoning damage and is knocked prone on a failed save, and half as much damage on a successful one and is not knocked prone. This uprooting of the land turns the wave's area of effect into difficult terrain until the end of your next turn.
