Boss Abuse is a way in which Boss Characters are 'abused' to gain high amounts of exp. There are many ways to do this. The most common method of Boss Abuse is the concept of using a Boss with a constant way of regaining Hit Points to train units. This is most often applicable with Bosses that stand on certain spaces that give them Hit points back at the beginning of their turns, such as the Gate spaces in certain Fire Emblem games. This tactic may cause lowered experience points over time, in Fire Emblem: Shadow Dragon and Lunatic Mode in Awakening.
