Before I got into this situation, I had already received the shape of a werewolf in the fairy forest. after the beginning of this arc, I managed to use every cube of the card in the accessible area, including talking to the fairy several times. ((( and it's also a shame that most tf's can't find bad ends. And if it's serious, it's such a cool game that I've been playing for 28 hours and I can't stop!!!!))) . But I would like more details about the transformations, as in the bad end of the golden retriever. but even bigger, and more piquant. even add a little NSFW, but don't overdo it.
It's a little hard to follow bit if I understand it right, you are still stuck?
If so, you could upload your save file so i can take a look at it if you like. A possible site for this if you wnat to share your save file: https://ufile.io/
Otherwise it might be a bit hard to give advice if I don't exactly know where or how you are stuck. Or if you don't ant that senmding screenshots of what text you get from the fairy and cauldron as well as quest journal. might help me to see wher you are stuck.
And thanks! Glad to hear you enjoying your time with my game^^
