I have other mods installed, one of which gives more capacity for books. I never had issues with it, even with the additional mods, until now.

Everything is working fine for me. Maybe you already have the keypage, or you're unlucky and need to burn more books.

It seems to be bugged, Burning the book doesn't give me the keypage.

We created this mod without another mods. Using only Purple Tear code (this is why decks displayed as her). I have noticed this bug for a long time and I have no idea how to fix it. Sorry.

The only option is make Objet d'art pages deck, save, and then port it.

Apparently Objet d'art pages (while still equipable) will not appear if you view combat pages for editing the deck of characters with the passives (though they won't disappear if you add the passive while viewing the combat pages). I assume that this is either intentional (likely not as there is no mention of it in the mod or passive descriptions), or some code for having multiple decks was taken from TheVarious, as one of the passives in that mod allows for characters to have 4 decks at the cost of being unable to equip Objet d'art pages.

If it IS unintentional, is it possible to fix this? It would be greatly appreciated.

how do i exactly use this, im kinda confused

You need any book for an invitation.
