I cannot attest to a time limit at the boss as there's no purple fires it leads me to believe there's no time limit, however I've never killed the boss myself so I'm not sure if you get "Kicked out" after killing him x amount of time. I know if you leave the monks, according to Tibiabosses, another player can still be roped without the boss being there for example.
A no-logout zone is an area that does not permit the player logging off.
The following rules apply to no-logout zones:
- If a player attempts to log out in a no-logout zone they will receive the message You may not log out here!. They cannot log out.
- If a player closes their client (x-logging), their character will remain online until the daily server save, until they die, or until they are pushed out of the no-logout zone.
- If a player logs in and their character is in a no-logout zone, they will be teleported to their home temple. Generally, the only way this is possible is by staying in the zone while the game is saving.
