Thunderous Blast

A bright streak flashes from your pointing finger to a point you choose within range and then expands with a loud crash. Each creature in a 40-foot-radius sphere centered on that point must make a Constitution saving throw. Those within 10 feet of the origin become deafened for 5 minutes on the failed Constitution save and for 1 minute on a successful one. A target takes 12d6 thunder damage on a failed save, or half as much damage on a successful one.

The sound spreads around corners. At the end of the turn of a creature who has been deafened they can make a Con save to see if they end the effect.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 2d6 for each slot level above 7th.
