Erm....Cards. This is a very useful thing in the game, Using Card Mod you can make your party unbeliveable, especially on the 4th disc, dont be afraid to Card mod any cards, the only person to play with is the guy on the Ragnarok, and he isnt worth it, use Gilgimesh, Bahamut, and all Charactors cards, and Card alot of enemies, rare cards can be found in them.....also get all Junction abilities first and get Sum Mag+30% on Quezacotl to use on ATM-X092 Helps much!
