Spellbook Question

I know how to make spellbook-weapons, which I need. However, I'm having a problem with it. I want it so that when a unit acquires a 'Special Item', it is added to the Spellbook. Well, rather, when they acquire it, it is removed from the game, and then an 'ability version' of the item is placed inside the Spellbook. Any suggestions?

I was also was working on making an ability that is defaulted in every Spellbook, that when cast, removes all abilities in the Spellbook, and transfers them to items. Any ideas or suggestions? I was thinking something along the lines of string comparisons but am not sure.

You will need a different version of the spell book for every combination of items available. You cant add or remove to or from a book. You need different versions of it.

You can't add or remove....that ruins the entire thing then, thanks.

Try my spellbook system. Not sure how good it will fit for you, just make a boolean if the person gets the item.
