Crystal key

The Crystal key is created by combining the tooth half of a key with the loop half of a key. It is used to open a chest located in Taverley. The chest is in the long house with some druids, north of the Herblore shop. The only monsters who can drop a full Crystal key are Kree'arra and the Corporeal beast. The key can also be obtained from looting a Kingly Impling or an Elite clue.

The Crystal key can only be used once. After it is used, it disappears. The chest's contents can be found on the Crystal chest page.

It may not be used with the steel key ring, as that is only used for reusable keys.

At current Grand Exchange prices it costs coins less to buy the two key pieces and put them together yourself rather than buying the whole key.

Halves of keys can also be obtained as a reward from the Evil Tree Distractions and Diversions event, Gnome Restaurant activity and the miscellania.
