Leveling Early in Kingdom Hearts: Waka Method
Chances are if you are a fan of Square Enix, you have most likely played Kingdom Hearts. And unless you can see into the future (or are on your second play through you probably didn't see the fight with Leon/Squall coming in Traverse City. Eager to continue the game I left Destiny Island quickly and ended up falling victim to this trap. After completing the game I decided to go back and attempt to win the fight with Leon/Squall. To boost my chances I decided to try to level a few times to help me in the fight as I would have more abilities, more health and deal more damage. After wasting time fighting Sophie over and over and then fighting Riku over and over to gain some level ups. However, after a awhile I discovered there is an easy trick to leveling up quickly, gaining a lot of experience in one fight on the Destiny Islands.
The character that you must fight is Wakka. Although he gives very little experience when you defeat him, this isn't the objective we are trying to achieve during the fight. Wakka's main weapon is the blitz ball that he carriers around and throws at you, you will find that, if you hit the ball you receive one XP point. And this is the main idea, however one problem presents itself, after the ball is hit it seems like the ball is attracted back to Wakka damaging him. This will also cause him to become dazed and lob two shots into the air which basically wastes time. So to avoid this you must stand far enough back that when you hit the ball it doesn't hit Wakka but sails over his head. And you also have to stand close enough that you don't leave the battle or the ball can't reach you. So try to find a range between these two to stand in and hit the ball.
Every time that you hit the ball you receive 1 XP and power balls give you 2 XP every time that you hit the ball. This stacks very quickly allowing you to earn quickly for this early in the game, and you don't have to go through the scenes after every battle cause you never leave that one. Usually using this method I play until I get to my common benchmark of learning the ability "scan". You can take this method as far as you want to though. You can get a few levels to beat Riku before leaving the island, defeat Squall or even get to level 99 (if you have that much time)..
