Chaos Legion Cheats

Revisit area 12 after you've beaten the game once. When at the area just before you encounter the boss a horde of enemies will appear in front of you. Continue to fight them as there will be two waves you'll have to go through. Make sure you have Thanatos in either his adult form or complete form and to also have his healing ability. When your health gets to a low point, summon Thanatos and stand in a corner to heal while having him continuously attacking until your ready to battle again. There are a total of 2104 enemies and it'll take atleast a good hour to go through them all. But if done right you leave with over 13 million exp and as a reward be given 30 exp gems. (take note that if the gems don't appear right away, run back to make sure all enemies are acounted for)

If you have completed level 12, The Sacred Capital of Rotari, all monsters in previous stages will have changed.

Go back to Stage 7, Misty Ravine. Once there, get within range of the first sword wielding enemy. Wait for them to charge, and then when they are about to attack you, use the Ground Zero manuever (must have the Guilt Legion equipped or have the Guilt Spirit Trancer).

It will not only kill the enemy in one blow, but give you a little over 48,000 experience points. You can continue using this method until the enemies stop reappearing and move on through the stage. It is time consuming, though. This is very useful if you are trying to level up your Legions.
