Concussive Wave

A wave of thunder and force forms a line of 25 feet long and 15 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Constution saving throw. A creature takes 4d6 thunder and 4d6 force damage on a failed save, or half as much damage on a successful one.

The sound for this blast can be heard from 1000ft away.
