I'm playing through FFVI for my third time now and am curious: what do you find to be the best place to level up before going to the floating continent? I recall the first time I played through the game I was unable to beat Phunbaba with Sabin and Celes because I never used either of them very much. The second time through I leveled everyone heavily in some deser where you fight the dragons that look like piles of bones.
What's the best place to level in the World of Balance?
