guys theres an easy solution if your using the PC version. Just get a saved game editor, go into item and give your self 99 Save Crystals
You know the crystal you get at the very end on the way down to fight sepy, it lets you save anywhere and its an item but in the game you only get 1! (i don't know if you can use it multiple times or if it disappears after using it once). if you can use it multiple times then give your self one and your set, otherwise give your self 99 copies of it, i'm sure you won't save 99 times in 1 session and even if you do you can just save, quit out give your self some more then keep playin
just don't go overboard with the editor and start editing your character stats and stuff cause that just ruins the game
