Arval's Arrow Swarm

You throw the arrow used as a material component into the air. A swarm of 50 arrows then rain down on a point within range of your choice. Each creature within a 20-foot diameter cylinder originating from that point must make a dexterity throw or take 2d10 piercing damage from the falling arrows. 

At higher Levels: When you cast this spell using a slot of 3rd level or higher, the piercing damage dealt by the spell increases by 1d10, and an additional arrow is required as a material component.
