There are ghosts haunting the houses of RuneScape, which you must find. Players can get hints for the locations of the ghosts by talking to either one of the monks, Brother Righteous (white) or Brother Heinous (red). Up to five ghosts can be found per wave and the locations will reset every two hours. You will receive a notification in the chatbox when the next wave begins. Before every wave, it is required to check in with the monks either in Varrock or Falador and start a hunt.
