Peace mode can be activated in the ruler's menu on the top right of the screen. Press the edit button () next to the Status field to access the drop down menu. Choose "Peace" to activate Peace mode. The cost is one parley item.
Peace mode remains in effect for twelve hours. No battles can be initiated against or by a player in Peace mode; however, any attacks already sent against a player in Peace mode will not be stopped by the change in status.
There is a six-hour cool-down period after the expiration of Peace mode, during which time another parley cannot be activated.
Peace mode does NOT affect the FS Tower; you can still fight in the FengShen when peace mode is active.
