- ―In-game tip, Epic Battle Fantasy 4
Ability Points, or AP for short are a gameplay feature introduced to the main series in Epic Battle Fantasy 3. They are special points earned after each victorious battle used for learning and upgrading character's Skills, which makes them vital for improving a character's capabilities in battle.
AP are awarded automatically to all living party members at the end of each won battle, similar to gold and experience. The amount of points received depends on the type and level of the enemy, with stronger foes yielding more AP. Each character receives the same amount of AP, including those in the backup slots, which helps prevent a single character from heavily fall behind the rest of the team.
AP are used to teach the character new skills, expanding his/her available moveset, or to upgrade character's skills onto higher level, improving their power and effects. Various skills cost different amount of AP, most of the time the more advanced the skill and the higher level it is upgraded into the more expensive it is.
In EBF4 special skills (those learnable by more than one party member) can be unlearned at any time, which resets their level and won't refund any Ability Points spent on them.
In EBF5 special skills keep their level when unlearnt, so moving a skill to another character is no longer an AP sink.
