So, while reading the description of this spell it says it will “immolate” a non magic weapon. Would it be possible to make a weapon disppear after the spell has expired?

Well… the description also says that it would work only on non magic weapons; that’s not true, it works even on enhanced weapons, everyone knows that. Anyway that might be nice to make the enhancement bonus decrease at every spell use over that weapon.

Do you think there’s a workaround that could be arranged in order to make that magic work on those ways (one or another: destroy the weapon or decrease the enhancement bonus?).

Just an idea, comments welcome!
Thank you
