lol
terra, replaying in expert mode i decided to spend 5 hrs at destiny islands leveling up to level 15 and defeating leon in 3 combos. oh, and 99 potions. if u feel like leveling in destiny islands, fight tidus, he gives most exp, even mroe than wakka when u hit balls back because the tech points u get from tidus dont hurt him as well. heres what u do:
when it starts run towrds tidus, attack the moment he lets out a attacking yell. tech point 2 right there. Then start running from him, when he starts chasing after you, turn around and run at him, when u are about to meet, attack and you will block his attack again and redo this until u level or feel like, stopping, then everytime you block his attack, combo him and end it.
