Thunderstrike

You point your finger and a bright streak flashes through the air striking a point you choose within range and then erupts with a cacophonous roar into an explosion of thunderous force and sound. Each creature in a 20-foot-radius sphere centered on that point must make a Constitution saving throw. A target takes 6d8 thunder damage on a failed save, or half as much damage on a successful one. If a creature fails its saving throw, it also has disadvantage on perception checks that rely on hearing for 10 minutes. A creature made of inorganic material such as stone, crystal, or metal has disadvantage on this saving throw. A creature that cannot hear has advantage on this saving throw.

A nonmagical object that isn't being worn or carried also takes the damage if it's in the spell's area.
When the spell strikes, a loud boom, audible from as far away as 2000 feet, emanates from the target location.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
