Cosmic Barrage

A barrage of cosmic meteorites crash in a line 50 feet long and 15 feet wide descending from the sky in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 8d6 radiant damage on a failed save, or half as much damage on a successful one. The meteorites make the impacted area rough terrain.

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 above 3rd.

Additionally: Cosmic Barrage will consume all orbiting comets and will add additional damage per comet.
