A free to play browser game in which you build a party of familiars to battle opposing parties. Although you do not directly control your party, you can pick and choose which familiars to place in your party. Familiars can be evolved by combing two of the same type to form a stronger familiar.
The game features a weekly rotation of events: PvP, a special dungeon event, and a raid event. Recently a King of the Hill style event was created.
Although players can acquire familiars for free or through doing well in events, spending money is required to acquire the legendary familiars that come from placing high in events.
