I have a Black Mage, White Mage, Red Mage, and a Warrior. Equiped with great items, and all, that can use magic, have close to the same spells, and all have at least one or two level four spells. Im beating the boss's, and the mobs easy.

I know I will have to change them when I get further into the game, but what im saying is, with this party, im doing pretty good.
