Earth Wave

You strike the ground, sending forward a shockwave shattering the ground. Each creature in a 30-foot cone must succeed on a Strength saving throw or take 8d8 bludgeoning damage and is pushed 15ft away from the caster. A creature that succeeds on its saving throw takes half as much damage and isn’t pushed.

In addition, unsecured grounded objects that are completely within the area of effect are automatically pushed 15 feet away from you by the spell's effect, and the terrain in the cone becomes difficult terrain as the ground is shattered from the spell.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
