Brandan's Kinetic Railgun

A blast of kinetic force forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Constituition saving throw. A creature takes 8d6 force damage on a failed save, or half as much damage on a successful one. On a failed save the creature is pushed back 30 feet.

The force breaks wood and stone objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
