Crushing Stone

You hurl a magically conjured stone boulder at a point you can see within range. Each creature in a 10-foot-cube must make a Dexterity saving throw. On a failed save, a creature takes 5d10 bludgeoning damage and is pushed 15 feet directly away from you, falling prone on the ground. Creatures who succeed on their save take half as much bludgeoning damage and are not pushed away or knocked prone.

Additionally, the boulder shatters upon impact, causing the ground in that area to become difficult terrain until cleared. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
