Boss Battle - Behemoth
This battle is pretty easy. Just jump on his back, lock on the head and attack. Once his horn begins to gather energy, that means he's about to unleash a somewhat devastating lightning attack, so get away from him to avoid it. Cast Aero on yourself and heal when necessary... that's about it.
After the battle, there'll be a short dialogue between Sora and the princesses. You'll also get the Firaga upgrade. Now all that's left is the End of the World
, so feel free to finish whatever side quest that needs completing. Also, don't forget to go back to the Library in Hollow Bastion
and talk to Aerith for the Ansem Reports 2, 4, 6, 10
, then to Belle for the Divine Rose
keyblade. Be sure to go back to the Grand Hall as well for the Oblivion
key chain and Puppies 61-63
. When you're ready, ride your Gummi Ship to the final area.
