Allow us to use Staff Spells on other weapon set

Build fantasies like Mjölner casting lightning spells feel so boring and dull already because of the lack of unique casting animations with it and not enough variety of spells but I apparently can't even cast other discoverable lightning spells with it also. The gatekeeping of these other skills/spells by requiring to hold the weapon ruins the joy and variety of buildcrafting. If you want people to use them fully with their innate weapon then incentivize it more to be stronger or utility-based rather than force players to be stuck with it to use and ruin whatever build fantasy the player intended.

Its wasted potential. Customizable aesthetic gameplay = more fun = more publicity = more players.
