Players summon fighting units from the RuneScape world, including a King Black Dragon, which despite being the most powerful unit in the game is available even to non-members. These are used to fight other players, with up to 8 different players per game. There are 75 distinct units, although the most a player can have available during a single game is 41. Members can play Rated games, which can earn them runes to buy additional fighting units, gods, equipment and prestige coats of arms.
