Water style water shark bomb

A shark made of water forms from your magic launching out in a line 70 feet long and 5 feet wide blasting out from you in a direction you choose. Each creature in the line must make a constitution saving throw. A creature takes 4d6 bludgeoning damage and 4d6 piercing damage on a failed save, or half as much damage on a successful one.

The shark destroys loose objects in the line that aren't being worn or carried.
