Hmm, when you say you have your Unfinished Curtana, are you actually using it for everything? I(f you are, I'll stop you from entering right there. That will earn you a lot of ridicule - as outside the few parts of the relic where you need to kill with it (Murder 24 beastmen of XX YY or ZZ type, and hydra), it is a piece of crap. You want to use at the very least your ilv. 55 Grand company, if not an ifrit HM (ilv. 60) or garuda HM (ilv. 70) primal weapon at 50, especially so for when you are doing the relic quest.
