I remember being super high level when I first got to the moon (before fusoya) (around 35 or 40). It's not always just about levels, get the BEST equipment you can possible (not just the shop gear).
Yes equipment, and also battle strategy. Change it accordingly to how the enemy reacts. Me, my levels are extremely high, I just train for ages, it's what I always do.
my levels were so high that when i first got cecil as a paladin, i didn't leave that grinding spot until everyone was at least level 30.
i have just leveled my party up by about 4 levels and i still have a problem When i revive my party Golbez kills them all before i get to heal them
what you should to, have Rydia phoenix down, and Cecil Cura on the newly revived person, get your cleric first, then get everyone else, make Cecil use Libra on Golbez, and Rydia summon according to weaknesses, it should take one summon and 8 turns, or 2 summons and a few more turns.... It was relatively easy for me... of course I read a faq...
