As I understand the magic item creation rules, you can craft 50 arrows (or other ammo) just like crafting a weapon. Spell storing is a +1 equivalent weapon enhancement that lets a spellcaster place a 3rd or lower level spell in the weapon so that it goes off when the weapon hits. My question is, could a wizard make a batch of fifty +1 arrows of spell storing, then spend a week or so putting spells in each one, then lets the party archer shoot them off in battle, releasing a spell each time without further interaction needed from the wizard? It seems like a relatively cheap way to effectively turn the archer into a second spellcaster. Thoughts?
