Crystal chest

From Old School RuneScape Wiki
Jump to: navigation, search

The Crystal chest can be found in the house directly south of the Witch's house in Taverley. The chest is locked and can only be opened using a crystal key, which is made by combining a loop half of key and a tooth half of key. Attempting to open the chest without the crystal key yields the message: This chest is securely locked shut. Opening the crystal chest grants a variety of rewards, which will always include an uncut dragonstone.

Opening the crystal chest is a requirement for the medium Falador Diary.

Possible loot[edit | edit source]

The expected value of the crystal chest is 23,452.25[1], while the cost of the loop + Tooth is currently 21,575. Crystal key is 21,704.
