BATTLE SYSTEM:
The battle system is quite similar to those of past Final Fantasy games. Each character gets a turn in battle. You can switch characters in battle also. To do this press L1. To view the battle order there is a box on the right part of the screen each character that is out has their picture on it and that's when they will next get a turn.
USING SPELLS:
When you want to use a spell go down from your attack box and choose black magic or white magic, whichever one you want to use. Than select magic you want to use. The number next to the magic spell is how much mp (magic points) it will cost you. Check to see how much mp you have by viewing it to the right of your hp.
USING SKILLS:
When you learn skills you can use them during battles. Just go to your skills in your attack menu and choose the one you want to use. Skills usually effect your enemies in different ways, ie. Armor break decreases their armor and defense power break decreases strenght and triple foul put sleep silence and darkness on them. You can learn many different skills on the sphere grid
SPECIAL:
Special moves you can do on the attack menu are usually things like steal, cheer, jinx ec. They help your stats during battle ie. cheer increases party's defense and strength. You can also learn special abilities like steal and use. Steal is used to steal items from enemies and than you can use use to use the items ( that's a lot of use) anyway.
OVERDRIVES:
Overdrives are pretty basic. There is a red strip under your characters hp that will show you how full your overdrive gauge. If you've played previous FF than overdrive is like LIMIT. In the character menu (press triangle out of battle) you can choose overdrive and change the way a character gains their overdrive. Use overdrive when your gauge is full these attacks inflict more damage on an enemy or some on enemies. For Kimahri's overdrive use lancet on certain enemies and he will learn their abilities.
