Thundercrash

After a brief wind-up you hurl yourself in a straight line, up to 60 feet and provoking opportunity attacks, towards an area that you can see within range with blinding speed, then landing with an explosive shockwave. Any sufficiently thick walls or obstacles (at your DM's discretion) will stop the movement and otherwise resolve the spell as normal.

Each creature, except for you, in a 10-foot radius originating from you, must make a Constitution saving throw. On a failed save, a creature takes 3d10 thunder damage and is pushed out of the area of effect, away from you. On a successful save, the creature takes half as much damage and isn't pushed.

In addition, unsecured objects that are completely within the area of effect are automatically pushed 20 feet away from you by the spell's effect, and the spell emits a thunderous boom audible out to 400 feet.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 for each slot level above 3rd. The area increases by 5 feet if cast with a spell slot of 6th or higher.
