AP (Ability Points) are crucial for learning new abilities and mastering classes. The most efficient way to grind AP is to repeat missions with low difficulty but high AP rewards, such as 'Poachers' or 'Wanted' missions. Equip weapons and armor that grant abilities you want to learn, even if they aren't the strongest. Once a unit has learned all abilities from a piece of equipment, they no longer gain AP from it. Rotate equipment frequently to maximize AP gain across your clan. Dispatch missions can also be a passive way to earn AP for units not actively participating in battles.
