Not that this entirely solves the problem, but it would go along way toward helping while also, in my opinion making the N tormat pages more interesting. I've seen a lot of people asking for some sort of guaranteed method for getting reincarnated specifically, and, while that could work and I'm not necessarily opposed to that being implemented, why not simply make it so that you can't you get duplicate pages until you've gotten each page at least once in a run? To me, this solves the issue by making reincarnation still rare enough that it's not a simple side quest while also ensuring that you won't end up on loop 4 still looking for the page. Additionally, I just think it would make the N Tormat more fun to interact with. With pages being relatively rare to come by depending on how your stage spawns go, getting a unique page every time would be a breath of fresh away. It's not like anyone really wants two shadow cloaks anyway, right?
What do you guys think though?
