Yeah, so I just completed the game, and I just realized I had rare foods syndrome. Lol. I dunno if this happened to anyone else, but I found that, whenever I got super rare foods, I would save them for later. But later never really came. For example, when I got the legendary cake recepe, I was like, OH MAN! this is gonna be SOO useful for the final boss. So, even though I had it, I never used it in fights like the sun temple and the Mithalas Cathedral (Where I REALLy could have used it). Then, when I did get to the final boss, I was so wrapped up in the fight that I forgot about it. So I never got to see the legendary cake in action. Same thing goes for the divine soup, or the plump perogi. I kept saving them for some super encounter that never came. Has this happened to anyone else?

BTW, I found a really helpful was to stay alive against the creator's 5th form. After he fires his super laser, he raises his hand and shoots 5 little energy balls. Instead of running away, I found that absorbing these shots in spirit form almost eliminated the need for health foods. I dunno if other people already knew this, but that strategy allowed me to beat the creator first try using just 1 full-health poultice.
