Best Level up hints and tips for Kingdom Hearts II

Best Level up

First, defeat Luxord in Proof of Existence for best results. Equip the Gullwing Keyblade (it has the special "Experience Boost" ability) and the Experience Boost ability through your Abilities. Go to The World That Never Was and go to Proof of Existence. The Experience Boost ability only activates when you're in Critical status... In other words, when the alarm is going off to heal. When this happens, DON'T HEAL! Allow yourself to be dropped down to a critical state by the Assassin Nobodies that are right outside the little doorway in the balcony part of Hall of Empty Melodies. As soon as you do that, use whatever level Gravity spell you have on them to gather them together, then blast them with a Thundaga spell! Go all the way down to the elevator near the moogle. After you get to the bottom, go out and right back in. As you're following this, keep to your Gravity and Thunder spells. Make sure you have a healthy Ether stock in case you have trouble with gathering the MP Balls the Nobodies drop. Kill ALL Nobodies that stand in your way! DO NOT attempt to kill Sorcerer Nobodies, they'll screw you over!

This will rapidly shoot your level up!
