Arcane arrow

You create four spectral arrows and a magical bow. The arrows manifest on your back, and the bow appears in your hand. As a bonus action and as a part of the bonus action used to cast this spell, you may shoot one of the arrows out of the bow. The bow uses your spell attack modifier for attack rolls. On a hit, the arrow deals 1d10+your spellcasting ability modifier piercing damage. The bow has a range of 30/90 feet. The bow and arrows disappear after all arrows have been fired or the duration times out.
