Eroe's Hail of Stone

You cause the handful of stones, rock, marble, or similar material to fly in a strait line 30 feet away from you. The materials stop early if they impact against a solid surface. The first creature in the materials 30 foot line when you cast the spell must succeed on a Dexterity saving throw. On a failed save, the materials strike the target and stop moving. When the materials strike something, the materials and whatever they strike each take 2d4 bludgeoning damage.

This spell's damage increases by 2d4 when you reach 5th level (4d4), 11th level (6d4), and 17th level (8d4).
