Arcane Fusillade

You target a 20 foot area you can see and fire a salvo of arcane bolts that rain down and detonate on physical contact. Everyone caught inside takes 8d6 force damage on a failed Dexterity saving throw, or half as much on a successful one. The target area has a 20 ft radius and a 60ft height, as the projectiles first fly up before raining down on the targeted area.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
