Tectonic Clap

The caster holds a firm stance and begins to produce a loud thunderous clap from the force of their hands colliding together. The force causes the ground in a 50ft circle centered on the caster to completely shatter, making the area around the caster difficult terrain. Any creature, other than the caster, within range of the attack, must make a Con saving throw taking 4d8 force damage on a failure and half as much on a success. A creature is knocked prone on a failed save.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
