The Best Way to Level Up

The best place to level up anything is usually in North Cave(Crater).If you are trying to get your AP up then fight the little red balls down pretty close to the bottom of the crater.If you are trying to get more EXP, then fight the "Magic Pots" and the "Master Tonberries."To get your limit up, fight something that has quite a bit of HP, like the dragons. Manipulate it, make it hit you, then use your limit. If it's a limit you use on your self, just keep miming it until you think it has been used enough. If it's a limit you use on the enemy, use it then cure the enemy, then repeat the process.To get more Gil you can fight just about anybody. Most enemies in North Cave will give you a lot of Gil.
