You strike the ground and unleash a tremor of seismic force that tears apart the earth around you in one of the following shapes chosen by you when the spell is cast: a 30-foot line, 5 feet wide; a 20-foot cone; or a 10-foot-radius circle centered on you (but not including the space you occupy, which is unaffected). This wave of destructive force deals 4d6 bludgeoning damage to creatures in the area, or half as much on a successful Dexterity saving throw. Medium or smaller creatures failing their save are knocked prone. In addition to this initial shockwave, the affected area is choked with rubble. This area is difficult terrain, and it is so unstable and shifting that creatures on the ground entirely within the affected areas have disadvantage on Dexterity checks (but not Dexterity saving throws). You can cast this spell only on a surface of earth, sand, or stone. It has no effect if cast within a wooden or metal structure or if you are touching the ground.
