Electric Dart

You send a lively flash of electricity towards a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 lightning damage, and any creature adjacent to the target takes 1d4 lightning damage as the spark leaps around. The damage increases at 5th (2d8 and 2d4), 11th (3d8 and 3d4), and 17th level (4d8 and 4d4).
