A strange device is an item used in the Hot & Cold challenge of a beginner or master clue.
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. The player must have an active clue step directing them to one of Reldo or Jorral to obtain a strange device, but once obtained it does not need to be returned and can be kept in the bank. Note that one must have completed Making History before Jorral will give them a strange device for a master clue.
The strange device changes temperature as the player moves about. 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. The warmer the key gets, the closer the player is to the treasure. Clicking "Feel Strange device" gives information on its temperature, and if solving a master clue, will deal 3-8 damage to the player each time as well (which can be fatal).

While following a master clue, when you dig at the dig spot you will have to face enemies depending on whether the area is single or multi-combat, so remember to bring combat equipment, food, and potions. If the area is single combat, your opponent will be a Brassican Mage that uses a typeless projectile attack. In a multi-combat area, you will instead face three Ancient Wizards which use different combat styles. The melee wizard can also poison you, so a means of curing poison should also be brought if your destination is in a multi-combat area.
