The party system is a system of 2 players or more. They get xp by killing enemies. So if one member kills an enemy, all the other party members will get xp points. The member limit for normal members are 8. For a VIP member, their total allowed party members is 16. The party members can talk to each other in chat in private using a special command by typing /p [msg] which will message all other party members on the same server. The party members will however not obtain xp points when one member completes a quest? (unconfirmed).
