During fights, a hero can gain xp during the following actions:
- When striking the final blow on an opponent, the striking hero gains xp.
- When completing a fight, xp is gained and spread among all heroes still standing.
- When a succesful Assist is done, the assister gains xp.
The xp gained depends on the opponent: the higher the attributes, the more xp will be gained.
Heroes level up automatically whenever enough xp is gained to reach a new level. This results in increased attributes. The way the attributes are increased is controlled by the Growth Divvying settings of a hero.
