Arcane Barrage

As an Action, you expend a 5th-level spell slot to send a barrage of arcane force at a creature within range. Make a ranged spell attack against the target.

On a hit, the target takes 6d10 Force damage. Creatures of your choice within 1.5m of the target must make a Dexterity Saving Throw, taking 3d10 Force damage on a failed save or half as much on a successful one.

At higher levels. When you cast this spell using a spell slot of 6th level or higher, the initial damage increases by 1d10 for each slot level above 5th.
