New AP System After the Battle, you only gain APs in FFX. The EXP System is gone for now and APs are only used in Leveling Up. The APs you gained accumulates and at a certain point, it turns to S.Lv (Sphere Level). This S.Lv can be used in Sphere Board. Sphere Board A new Leveling Up system, Sphere Board has made in FFX. By using Sphere Board, raising characters have changed widely. Even every characters have their own job or field, this can be modified depending how you raise your characters; meaning Tidus, the main characters has Time Magic set in the very first part of the game, however, you can teach him White Magic which is impossible to learn naturally for him. Lulu, a Black Mage can learn White Magic, Yuna a White Mage can learn Black Magic. This can be useful since usually White Mages has low attack, you can teach them strong and offensive Black Magic. This can be applied to all characters. But unfortunately, Summoning cannot be learned by Sphere Board since there¡¯s no Block that has Summoning and Yuna¡¯s the only one who can Summon and the only one who¡¯s a Summoner.
