Blast

A powerful explosion of force erupts from a point of your choice within range. Each creature in a 10-foot-radius sphere centered on that point must make a Strength saving throw. A creature takes 2d6 force damage and is knocked 10 ft. Away and knocked prone on a failed save, or half as much damage and 5 ft. of knockback on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 and the knockback is increased by 10 ft. for each slot level above 2nd.
