To create magic pyre logs, players must first obtain 4 doses of sacred oil. Sacred oil is created from olive oil during the Shades of Mort'ton quest or minigame. Once the sacred oil has been obtained, players will need to use four doses of it on some magic logs. These logs will then become magic pyre logs and the player will be granted 60 Firemaking experience.
Once a player has obtained the magic pyre logs, they may place them on one of the funeral pyres around the edges of Mort'ton along with a set of shade remains (Loar, Phrin, Riyl, Asyn, or Fiyr). When the player lights the pyre, the spirit of the shade is released with a short animation, and a shade key or a small sum of coins will be added to the player's inventory or money pouch. The type and colour of the key depends on which type of shade remains are used, with higher level shades leaving better keys.
