Unlike @Arena, there's no participation fee.
However, you can't join unless you belong to a guild, nor if your guild's color is still set to white (#ffffff).
Once you join, members of each guild are automatically put into respective parties.
Up to 8 players can participate, and each guild can have up to 4 members.
The battle begins with @Start.
At the start, everyone gets given the same waiting time (ProgressionSpeed + 2 seconds) in order to give players time to set their party positions.
Battles won't end until there is only one guild left, and the winner gets determined after using @Start.
If there's no party with the required number of rounds won, the next battle will start with everyone getting a full HP recovery (MP stays as it was at the end of the last battle).
The quest ends when the battles have concluded, or when 10 rounds have passed without an overall winner. At this point, leave the quest with @RunAway.
