1. Mining: The warden doesn't care if jailbirds mine ore to their heart's content. If fact, there isn't much else to do.
2. PK Freely: Murderers (PKers) are free to kill each other as often as desired. Nobody cares about what happens in jail, so you can PK without your PK points increasing. When you revive yourself, you'll still be in jail, but all your cool items will be lost or stolen by other PKing players. Ain't life in jail great?

Tips: No teaming-up in the jail. Teams are forbidden.

Guild War Jail

Player who was killed in the Guild War will be put into the Guild War Jail if he or she was not revived by the Water Taoist. The imprisoned player can get out of the jail after 10 minutes. Other settings are the same as that of the normal jail.
