Astral Barrage

Ten Bright projectiles of concentrated energy Fall from the sky and target Ten different Creatures or Objects you can see within range. Make a ranged spell attack roll against each Target. On a hit, a target takes 4d8 Force damage. Additionally, hit or miss, each creature in a 10-foot-radius (including the targets)Sphere centered on each of those targets makes a Dexterity saving throw. A creature takes 3d6 force damage damage on a failed save or half as much damage on a successful one. A creature in the area of more than one sphere is affected only once.

When cast using a higher level spell slot: For each slot level above 5, the Initial damage to the targets increases by 1d8.
