Celes is half that level. She's at level 7. In fact, nobody is above level 10 except Gau.

I don't want to go through this smurfing dungeon again, but how do I get level 4 flare?

Edit: Wait a smurfing minute I can summon Ifrit! And Maduin!! And I'll use shoat to petrify the boss in one hit if I ever make it that far.

Double Edit: and I can summon carbuncle, which means I don't need the wall rings and I'll deal more damage to the naughties. I have to be careful with my MP consumption, though. I want to save some tinctures for the WoR.
