There are three parts to the final Boss: the hand which is now called the Pod, the Wisp that likes to bounce around, and the Core. You cannot damage the Core until you take out the Wisp. First, make sure that the characters you put on your team will follow the law at any cost (for example, "No Reaction Commands"). Two characters should have perfected the Dual Swords passive ability from the Ninja class, which allows you to attack twice with the basic attack. Have one Cannoneer with the "Ether Shell" ability, which can restore the MP of any character that needs it. To keep up the health of the team, have a White Mage that has all three forms of Cure (Cure, Cura, and Curaga), Esuna, Raise, and ReRaise. Use the Cannoneer to restore the White Mage's MP from the start. Another character that will make victory easier is a Ranger (which is a Seeq class) with at least two abilities, Mirror Items and Camouflage. The final character can be anything desired (for example, a Fusilier so you can attack from a distance). Before you start the battle, make sure you have a good stock of X-Potions and Hi-Potions. Another useful item is the Remedy. Have the characters with the Dual Swords follow the Wisp and strike it. On the Cannoneer's first turn, have it restore the White Mage's MP. Have the Ranger move over to the Pod, and use Camouflage until it reaches it. The White Mage should be put somewhere where it can heal anyone who needs it. The final character should go somewhere depending on what it can do. If the character can attack from a distance, like a Fusilier or a Sniper, send them to the center so they can attack the Wisp wherever it goes. If they can only attack from close up, have them follow the Ranger to the Pod. The Ranger should use Mirror Items and Mirror X-Potion to attack the Pod. Keep doing this until its HP reaches 0. After defeating the Pod, it will be easier to move around. The Wisp and the Core have high-damaging attacks and can cause several status conditions, which is why you need the White Mage. After attacking the Wisp several times, it will move to one of the two other locations. Have your characters follow it, and damage it as much as possible. The battle is much easier when you get rid of the Pod, because the Wisp likes to hide behind it. Remember that the Core can use its turn to heal the Wisp, however this is sometimes a good thing because the Core cannot hurt you while doing that. After killing the Wisp, which should be done after finishing off the Pod and using the Ranger's Mirror Items technique to use Mirror X-Potions on it, the Core will transform into its attacking form. Send all your characters towards the Core. The Core has several attacks, but the most damaging will hit all of your characters. Have your White Mage cast ReRaise before this to make sure that your characters will be automatically revived after being killed by these deadly attacks. The only characters to attack the Core are those with Dual Blades and the Ranger. Keep dealing heavy damage while protecting your characters with the White Mage to defeat the Core.

When fighting the final Boss, it has the Pod (hand), the Wisp, and the Core. Normally you have to take out the Wisp and the Pod before you can damage the Core. However, if you have an Ultima attack and use something to replenish MP immediately at the start, then go directly up to the Core, you can do the original damage of what the Ultima attack would have done.
