The Duty Finder allows players to undertake multiplayer duties without having to form a party on their own. The Duty Finder can be accessed with the "U" key or by selecting "Duty Finder" under "Duty" in the main menu.
Duty actions are special actions that are available only during the course of specific quests or battles. Duty actions are used by left clicking their icon, but can be bound to other keys. Some duty actions can only be used a limited number of times. Deciding when or when not to use them can mean the difference between victory and death.
