You can access the fightclub debug menu by clicking on Debug (only on the test server) or by wearing a dev cap while talking to Rouge.
$Duel_Enabled ($fightclub_enabled % 5)
This variable is like the main breaker of the fight club. When set to 0, all timers are stopped, users can no longer call #duel and Rouge do not offer any option related to the fight club. Turning this off will completely disable the fight club.
$fightclub_bm_enabled ($fightclub_enabled % 6)
This variable enable or disable the Battle Master. If players are already in the PVP cave or at Brodomir's while this variable gets disabled, they will still go through the cleanup procedure and get warped to the fight club when they quit.
$@fightclub_password$
This variable is the password that is asked when you enter the fight club. It has no practical purpose.
$@Duel_TimeBeforeNext
This variable is the number of time (in seconds) to wait between each battle. When a battle ends, a timer is started and the next battle is scheduled after.
$@Duel_TimeBeforeWarp
This variable is the number of time (in seconds) to wait before warping the players into the ring. This is the "The next battle is foo vs bar. this battle will start in X seconds"
$@Duel_TimeBeforeStart
This variable is the number of time (in seconds) to wait after all players are in the ring to start the battle. When players are warped into the ring they see the message "Get Ready" and X seconds later "Go!". This allows both players to move to desired location before getting @killer
$@Duel_TimeLimit
This variable is the number of time (in seconds) before ending the battle with no winner.
$@Duel_QueueLimit
This variable is the maximum number of duels that can be queued at once. When the queue is full, players have to wait to add another battle to it.
Restart fightclub
This option calls the "fightclub_EmergencyWipe" function which empty the queue and clear all temporary variables. This function should be the equivalent of rebooting the server.
