A Railgun spell
The inspiration for this spell is from an anime called A Certain Scientific Railgun.
Someone probably made this, but I can't find it on Reddit.
Note: This railgun use explosion, not arrow.
Requirement: CAD (Ivory is probably the best), a projectile and a loopcast bullet

put these two spell onto your CAD, fire arcade coin at target and use the Railgun spell.
Here is a creative version that deal more damages and has lightning effects.

Is this useful? No, but I think it look cool.
I tested it in 1.12.2, should work in newer version too. (I think)
