Riyl remains are an item found and used in the Shades of Mort'tonminigame. To obtain these remains, the player must kill a Riyl shade, located in the underground tomb. (Note:To enter the tomb, the player needs at least a bronze shade key, obtainable by killing and cremating a Loar shade.) They may also be encountered while Temple Trekking on easy route. To burn the Riyl remains, the player needs some pyre logs (see table for more info) and a tinderbox. First place the pyre logs on a funeral pyre, followed by the Riyl remains, then ignite the pyre. This will grant the player Firemaking experience (see table), and 59.5 Prayer experience.
Once burned, a steel or black shade key (or some coins) will appear next to the pyre. The keys can be used to either enter the tomb, or open the corresponding coloured doors to chests containing valuable items.
Players may only use Willow pyre logs or better to burn Riyl remains.
