I'm playing the game yet again, and this time I've found my favorite combo. I have a Knight with two swords, a summoner with either Black or White Magic mastered along with Half of MP and Punch Art (Chakra to restore MP), a Ninja with Elemental, a Lancer with the Steal ability, and th fifth is sort of up for grabs. I usually either make it another magic user (like Wizard) or Samurai, depending on the battle I'm about to go into. All of them have Autopotion (and only X-Potions in inventory) and Teleport.
