Aftershock

You transform natural earth such as dirt and stone in a 30- foot radius around you into broken earth. Each creature of your choice in the area must make a Dexterity saving throw, taking 4d10 bludgeoning damage on a failed save or half as much on a successful one. Structures in the area automatically take this damage. For the duration, the area is difficult terrain for creatures except you.

While you are in the area, you can use a bonus action on each of your turns to create an aftershock. Each creature of your choice in the area must succeed on a Strength saving throw or be pushed up to 10 feet away from you.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the radius of the area increases by 10 feet for each slot level above 5th.
