Two intertwined bolts of energy shoot from you hand. Make a ranged spell attack against the target. On a hit, the target takes 2d4 lightning damage and if the target is concentrating (on a spell or ability), it makes it's Constitution Saving Throw with disadvantage.

The spell's damage increases by 2d4 when you reach 5th level (4d4), 11th level (6d4), and 17th level (8d4).
