The Shadow Dungeon is the dungeon used during Desert Treasure, where players fight Damis to acquire the shadow diamond. 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.

The dungeon can be difficult to navigate, as it has a maze-like structure. Once Damis is killed during Desert Treasure, he will not reappear in the dungeon. After Desert Treasure this is a good, easily accessible place to train Magic. All of the monsters 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.
