I know that it is very strange XP I don't know anyone else that hates Hot and Cold, like me XP
I think I'm unlucky, or I don't have the patience to Hot and Cold... I never find much Chocographs >.< I always promove my Chocobo to Reef and stop there...
But I started the game again, and I WILL get a Sky Chocobo >___<

And one more thing: Why is Vegnagun easier than Necron? O_O
