You channel the power of the earth into a devastating rampage, causing the ground beneath you to shake and tremble in a 20-foot radius centered on you. Each creature other than you in that area must make a Dexterity saving throw. On a failed save, a creature is knocked prone, paralyzed until the start of your next turn, and is pushed to the edge of the area or pulled into the center (your choice). On a successful save, a target is moved, but you don't paralyze it or knock it prone. If the ground in that area is anything less than indestructible, it becomes difficult terrain until cleared.
