Brigandine: The Legend of Forsena Cheats - PlayStation

Play as the Esgares Empire
Press [L2] + [R1] + [Start] at the "General Select Screen". The difficulty selection screen will appear without a general being selected. Begin game play to control the Esgares Empire. Note: Press [Start] + [L1] + [R2] in the Japanese version of the game.

Easy experience
When fighting a very high level enemy, such as Cador, cast "Halo" on the creature you intend to level up, then fight him until his life drops less than 25. Hit as many x as possible for more xp, then finish him off with a level 1 monster. That killer monster will receive enough xp for 10 levels. Upgrading is possible immediately after the battle.

Easy win
Focus all of your attacks to the enemy leader. If their leader defeated, their monster will automatically retreat or be captured. Doing this will let you win the battle in less than three turns.

Upgrades
Not all upgrades are good, because the Rune cost goes up with it. Instead, train some units to level 20 before you start upgrading them. This way you can hold more units to train (for example: Dragon, Wyvern) Angels are an exception, since they get thrashed flat at non-upgrade, and after Arch-Angel, their next upgrade is 30 to Lucifer, the Fallen Angel.

Recommended Monster
The best Monster you should include in your party is Angel, Demon, or Nightmare. Angel can heal your characters, and its magic Divine Ray are very strong. Demon has magic Curse, which deals a lot damage. Nightmare has a magic dimension which can teleport enemy monsters that block your way.
