Blast Wave

A wave of thunderous force blasts out in a cone 50 feet long and 25 feet wide blasts out from you in a direction you choose. Each creature in the cone must make a Constitution saving throw. A creature takes 6d6 Thunder damage and is made prone on a failed save, or takes half as much damage and is not made prone on a successful one.

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.
