Barrage

You fire 3 bolts of condensed magical energy in a straight 30-feet line in front of you. The first creature in that line must succeed on a Dexterity Saving Throw or suffer Force damage depending on the distance between you and the creature. Within 5 feet - 4d6, 15 feet - 2d6, 30 feet - 1d6, or half as much on a success.

For each level of spell slots used to cast this spell beyond 1st, increase the damage by 3d6 at 5ft, 2d6 at 15 feet and 1d6 at 30ft.
