Stone key

The ' ' 'Stone key' ' ' is created by combining the Stone key loop with the Stone key tooth which are both obtained durin the Dragon slayer part 2 quest. It is used to enter Carmadon Dungeon.

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 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 and the Gnome Restaurant minigame.
