Compared to lightning arrow, whose initial damage is identical to this spell, this is at least a 2nd level spell if not 3rd.
I would also adapt some of the language from lightning arrow which begins with “The next time you make a ranged weapon attack during the spell’s duration, the weapon’s ammunition, or the weapon itself if it’s a thrown weapon...”

An idea that was itching my brain so I had to get it out. Not sure if I would use it
3D8 plus arrow damage seems a little over kill maybe 2D8+arrow and maybe a 1 minute duration

Lowered the added damage to 2D8...I like it
