 Characters used in battle gain experience levels, with larger amounts of experience being awarded depending on a character's performance in battle: once they have 100 experience points, a character automatically levels up. At level 21, a character's class is automatically upgraded. This upgrade can happen at level 10 if the player uses an item called a Master Seal. Once the class changes, the character is reset to level 1, while carrying over all the stat increases aggregated up to that point. Bonus experience is awarded by fulfilling secondary requirements outlined at the beginning of the level.
