Bullet Sphere

A 20-foot-radius sphere springs into existence at a point you can see, filling the air with bullets firing into the sphere from all directions. The sphere remains for the spell's duration. Each creature that ends its turn there must succeed a Dexterity saving throw or take 10d6 piercing damage, or half damage on a successful save. Until the spell ends, you can use your action to move the sphere to a new location.

At Higher Levels. The radius of the sphere increases by 10 feet for each level above 6th.
