Arcane Arc

You fling a bolt of pure arcane energy at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 force damage. If this damage forces the target to make a saving throw to maintain concentration on a spell, roll a d4, the target subtracts the number rolled from the saving throw.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
