Here's a general breakdown of the definitions for your stats. If you've played the game you have a general idea how it works. Taken from the wonderful writers of Wiki.
We use the following Stats.
Level: A units level is the defining point of the character, it denotes how much it has in the other stats. For example, a unit with a low level is considerably weaker than a high level unit. Levels are usually measured one at a time, unless a considerable amount of experience/Ability Points are gained at one time. Level also affects how much damage the user deals along with the other stats in most Final Fantasy games. As the unit gains levels, the unit will gain more power in the below stats.
HP (Hit Points): Hit Points are used to determine if a character is able to fight. When attacked, the total damage dealt is subtracted from the current HP. When the characters current HP is 0, the characters faints and is unable to fight. Some items like Potions and most White Mage skills can restore HP. Phoenix Downs can revive a fainted unit, usually with half their max HP.
MP (Magic/Mana Points): Magic or Mana Points are used when a character uses magic, or special skills. Black, White, Blue, and Red Mages usually use these to utilise their skills. In some games, they are restored periodically. Sometimes items or rest stops are required to restore them.
Exp. (Experience Points): Experience points are gained to raise the character's levels. To level a character by one, a certain amount of Exp. is needed. This amount is rarely constant, as it grows each time the character levels. Enemies grant Exp to the party when defeated, and generally, Bosses may either give a huge amount of it, or none. The Exp. received after a battle is usually shared by the whole party, reason why if a character fight a monster alone, he would receive the same experience as all of the characters together. We do allow group missions.
AP (Ability Points): [b]Ability Points are gained when a battle is complete and won. In most games, AP is used and gained to allow characters to master abilities. Generally, the stronger an opponent/group is, both in level and class (e.g.: Minions VS. Bosses), the more AP the character gains.[b] AP will buy you moves on the site.
Attack Power: Also known as Vigor, Attack Power is used to indicate how strong a characters Attack is. It is compared to the opponents Defense to determine how much damage is caused, if any.
Defense: Defense Power is used to indicate how well defended you are against physical attacks. The higher Defense Power a character has, the less damage he/she takes.
Magic Power: Magic Power is used to indicate how strong a characters magic skills are. For White Mages, it determines how much HP is restored.
Speed: Speed determines how fast a characters turn will come up in battle, and how often.
Dodge: Increases your change to dodge attacks.
