I went to the trouble of getting 100% for this game, and by that I mean full bestiary and item log, it does come with one asterisk however, which is that while the bestiary was completed legit, after enough time trying to do it the legit way, I eventually just had to give up and use cheats to fill up the item log, because oh boy are the droprates absolute trash, just unreasonably bad, anyway, as for the save files, there's 3 of them, 2 before the point of no return, 1 after, use them as you see fit
