The Shadow Dungeon is the dungeon used during Desert Treasure, where players fight Damis. To access the dungeon, players must use the ladder east of Baxtorian Falls, near Rasolo. To be able to see the ladder, players are required to wear the ring of visibility.
- Down a ladder east of Baxtorian Falls - A ring of visibility must be equipped to see the ladder. The ladder can be found within the fenced area north of the moss giants and south of Glarial's Tomb. These are located slightly west of the Fishing Guild.
The dungeon is a single combat area until players reach the area where Damis is fought during Desert Treasure. Once Damis is killed during Desert Treasure, he will not reappear in the dungeon. After Desert Treasure this is a good, easy accessible place to train Magic. All of the NPCs use melee so using the Protect from Melee prayer will reduce the amount of damage taken. Once in the area walk around and get all of the giant skeletons and Shadow Hounds to start attacking your character. Then you can use one of the multi target ice spells from Ancient Magicks to train Magic quickly. After all of the giant skeletons and Shadow Hounds are killed there is an area in the north-west of the area where you can wait until they respawn. This area is a relatively safe area and your character will only be attacked if a monster follows you into this area. Super energy potions are recommended.
- In the southern part of the dungeon, players can see the areas from Temple Trekking.
- Upon release of the Dungeon Maps on 27-May-2009 this area was not included, so no map of the Shadow Dungeon is available on the World Map.
