Global Quests are similar to quests except you are competing with other players to kill a certain number of monsters in a specific time frame.
Global Quests are declared randomly through out the day for different level ranges. If a Global Quest of your level range is declared when you are online you may enter it.
Once you join it you will be given a list of mobs which you must kill and a time frame to do it in.
The first participant of the Global Quest who kills all the target monsters wins and is rewarded a prize of quest points.
Areas in which global quest targets exist repop at a faster rate during a global quest to provide all participants a chance to kill the monsters.
