Ball Bearings + Thunderclap

You throw a handful of ball bearings into the air and cast Thunderclap, launching the ball bearings forward creating a shotgun-like blast.

Each creature in a 10-foot cube originating in a 10-foot cube in front of you must succeed on a Constitution saving throw or take 2d8 Thunder damage. The spell’s thunderous sound can be heard up to 100 feet away. On a failed Constitution save, the creatures take an additional 2d6 piercing damage.
