Arrowsplit

You enchant an arrow/bolt with magical properties to split into more arrows. When you fire the arrow/bolt it splits off into another separate arrow/bolt. Each separate arrow/bolt must be rolled with their own to hit roll and each arrow/bolt will trigger on-attack effects but only one can have your dexterity modifier  (example: hunter's mark).

At each higher spell slot level the spell creates an additional arrow/bolt (example: 3rd level you get three additional arrows)
