Its temperature is based on the distance of the treasure from the player, measured in the number of steps it would take to reach the treasure, ignoring any obstacles (this is the Chebyshev distance between the player and treasure). (if solving a master clue, you will also take some damage). To find your location, click on the strange device and it will tell you how close you are to the treasure. The beginner clue strange device can be obtained by talking to Reldo in the Varrock Palace library, while the master clue strange device can be obtained by talking to Jorral in the outpost north-west of West Ardougne. This is based on an older children's game. Hot Cold clues are clues in which a strange device will tell the player in the chatbox whether the player is Hot (close to) or Cold (far away from) the intended location to dig.
