Thundering Strike

The next time you hit a creature with a weapon attack before this spell ends, booming thunder audible to a range of 300 feet emanates from the point of impact. The target and each creature other than you within 10 feet of the target must make a Constitution saving throw. A creature takes 4d8 thunder damage and is deafened for 1 minute on a failed save, or half as much damage and isn’t deafened on a successful one
