I- I'm stuck in the Ice Cave because I abandoned the game for a long time and now I don't know what I'm doing there anymore. XD

III- Salamander. I messed up with savestates so that I couldn't level up anymore. I had to import a savestate for another version of the game I was luck enough to have not to restart from the beginning.

IV hardtype - Demon wall. And Lunar Bahamut. He handed my ass to me on a silver plate at least 10 times. And Zeromus, until I levelled up.

VII- Gaea Crater, after the Schizo boss battle. That bitch that Cloud is didn't want to climb the mountain.

IX- I couldn't find Jabberwook, so in the end I went to beat the crap out of Ozma with an all-mage party.
