Ashley's Railgun

A beam of crackling lightning shoots through your arm propelling a gold coin toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 lightning damage.

The spell shatters the coin into more than one fragment when you reach higher levels: two fragments at 5th level, three fragments at 11th level, four fragments at 17th, and 5 fragments at 20th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.
