Arcing Shock

You reach out your hand and let forth a bolt of destructive energy at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 lightning damage. You may choose to have the spell jump to another target within 5 ft. of the original target. Each time the spell jumps to an additional target the damage is reduced by 1.

This spell's damage increases by 1d6 and the number of times the spell can jump increases by 1 when you reach 5th level (2d6, 3 targets), 11th level (3d6, 4 targets), and 17th level (4d6, 5 targets).
