8. Boss Fight: Individer

Boss Fight Strategy: Individer
 

You will begin the battle with only Kisala in your party. In order to damage the Individer, you must first freeze it with the Freeze Shot. Only then will it become vulnerable to damage. If you do not have the Freeze Shot equipped on Jaster when you begin the battle, open the menu with and select “Change Equipment” and then “Subweapon” to equip the Freeze Shot. Once you use the Freeze Shot on the Individer, it will become frozen. Be sure to use Jaster’s Illusion Sword ability, and begin your onslaught on the beast. Also be sure to use Kisala's Dagger Slash ability since the Individer has a weakness to Ice element attacks. When the Individer recovers from its frozen status, use the Freeze Shot on it once more and continue attacking. If you need to wait for the Freeze Shot to recharge be sure to block while waiting because the Freeze Shot's recharge is very slow compared to other guns.

After sustaining enough damage, Lilika will join the battle, but the strategy for defeating the Individer remains the same. The Individer will begin to spawn multiple worm enemies to annoy you, but these are just distractions. The real target remains the Individer, and once you’ve depleted its HP, you will emerge victorious.
