yeah... the spell: "Bless Weapon" adds 2d6 damage VS undead. Is there any chance this can be added to ammo aswell. making the ammo plot at the same time so no exploiting be done? much like the continuous light spell.
There's ways to make special bullets already, and special arrows. Being able to buff ranged ammunition with flame weapon etc has been shot down time after time. Closest you'll get is the fact you can cast MAGIC weapon on darts, shuriken and throwing axes to make a stack of 50 temporarily +1 weapons.
But i still think you should be able to cast flame weapon on arrows/bolts/bullets. I mean, it's 99 shots so it won't be too strong anyway.
I would only approve of this if spells like magic weapon and flame weapon would also start working on ranged weapons/ammunition.
There are already ways around this. Many ways. They just happen to be something bit more interesting than the usual 'buff me up, Scotty'.
