|A mysterious key for a mysterious chest.|
The crystal key is used to open the crystal chest located inside a house in Taverley. It is created by combining a tooth half of a key with a loop half of a key, displaying the message "You join the two halves of the key together." The crystal key can only be used on the chest once. After it is used, it disappears. Some notable items that can be obtained from using one key are 3 rune bars, rune platelegs or a crystal key half. The chest has a 100% chance of receiving an uncut dragonstone.
This key may not be used with the steel key ring, which is only for reusable keys.
