I'm working on a walkthrough for the game, if you are after certain ones you can tell me the names and I can tell you where I found them. I don't have a complete list yet, just a bunch of notes (that are probably a mess >_>) I have to put together in the next day or 2. I am missing some late game ones though, I'm not done with my playthrough yet. In the last dungeon right now, and have post game to do afterward.
If you want a full list now, you can find it here :
