I have been saving my potion formulas for quite a long time now, as I hope to get a lot out of my alchemist in my battle tower, which I am just about to take from Laiken.
One of the last things I did before going to the final confrontation with Laiken, was to solve the "Buad Blood" quest in the Watermill in the village in Broken Valley. When I spoke to the "alchemist" in the cellar, I asked him to help out with some alchemy. Which he did, thereby taking away from me several of my best formulas.
Does this mean that my own alchemist in the battle tower (when I get it) won't have access to these formulas? If this is so, I'm tempted to try and find my old save file - even though this means that A LOT of gaming hours will go down the drain. I used up an armor potion formula and a substantial healing formula and whatnot...
Have I lost my formulas? If so, should I reload an old save? Or can I easily replace the formulas in some way?
