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 an uncut dragonstone and a variety of other rewards.

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 24,587.56[1], while the loop and tooth halves together currently cost 25,893 and a crystal key 26,168.
