You can get tf potions randomly on tf spots but only after having unlocked at least one tf potion which requires enough mastery with any tf. Under transformation masteries you can always look up how much you have with each form, what is already unlock and the next mastery unlock.
You can upload the save file pretty much to any site for filesharing and post the download link here in a comment. I am not on my pc currently so I cant look up which I am usually using for filesharing but pretty much any site should be fine.
As for the puzzle. As for the ouzzle if you like some hint: Alice is just her nickname. In some booshelfs across the dungeon you may find books that contain her true name.
A = 1 B = 2 C = 3
Hope this gives some good hints. If you need any more feel free to ask.
