Experience points

Experience points are how a character levels up. When a character participates in battle, they gain experience points. The amount of experience points gained depends on the class; lower classes such as Trainees will gain the most while higher classes like  Paladins will gain the least amount of experience points. The amount of experience gained also depends on how the battle went; if you did no damage you'll get very little, doing damage will get you more, and killing the enemy will yield the most experience. After gaining 100 experience the unit levels up to the next level.
