While building up forces in the form of supporting characters and troops, and enhancing them with powerups, the player tries to weaken the opponent by hampering them with effects and inflicting damage during battles. These battles are fought over "challenges", missions that each player can initiate. The winner of the challenge receives a specific reward as specified by the challenge. The dice are used to generate four different kind of abilities, needed for recruiting characters, doing damage, and generating support or opposition during the challenges and the Last Battle.
