We all know the Kingdom Hearts series is full of Game Breakers, but which is your personal favourite? For those who don't know, a Game Breaker is basically an exploit that makes the game much easier than it should be. It's not really a "cheat" per se since it's still part of the game, it's more like taking advantage of the game mechanics.
For me, my favourite is the way MP works in Kingdom Hearts II. By equipping lots of MP Rage and MP Haste abilities, you basically make yourself invincible. To elaborate: Curaga takes all your MP to use and heals you fully. MP Rage makes your MP increase when you take damage. MP Haste means your MP recharges faster after it runs out completely. The two abilities stack. This basically means if you equip enough, you can basically get attacked and your MP shoots to full. Combine with the Second Chance (leaves you at 1 HP after a powerful attack that would have otherwise killed you) and Once More (leaves you at 1 HP after a combo that would have otherwise killed you) abilities and you basically become invincible, especially if you also add Leaf Bracer, which makes you invulnerable while casting Curaga. As long as you can hit the shortcut, you can basically never die. Equipping the Ultima Weapon, which has the MP Hastega equipment ability, is also a major help. With this set up, even the final boss becomes a joke. Sephiroth is the only one who might still give you trouble.
