Examine | A crystal key can open it. |
The crystal key chest is a treasure chest located in Ivy Sophista's house in Taverley. A second chest is located in Prifddinas in the Iorwerth Clan section. The chests are locked and can only be opened by a crystal key. Attempting to open the chest without the crystal key yields the message: "This chest is securely locked shut." The crystal key is made up of a loop half of a key and a tooth half of a key; you can make the crystal key by using them with each other, or selecting the "Assemble" option. Opening a crystal chest grants a variety of rewards, which always include an uncut dragonstone. The crystal chest in Prifddinas grants slightly better rewards than the Taverley chest. The crystal key sells for more than most of the rewards, making it more monetarily satisfying to sell the key. When the key is used it disappears, so opening the chest is a gamble.

RewardsEdit
The chest loot always includes an uncut dragonstone, together with a random reward generated from 13 possible reward tables. Below are the values of the chest's contents, based on current Grand Exchange prices.
After an update, wearing a ring of wealth will increase your chances of getting a better drop.
It is only possible to obtain rune platelegs if you are a male character, and a rune plateskirt if you are female character.
It is a common misconception that you can obtain crystal weapons from the chest. The chest does not contain any of these items, as they are a quest reward.

Probabilities - Taverley chestEdit
- The probabilities in this section are an estimation based on the data of 1134 crystal chest loots on the Taverley chest, while wearing a ring of wealth.
Possibility | Percentage |
---|---|
Possibility 1: Fruit tree seed | 8.02%^{[1]} |
Possibility 2: Lantadyme seeds | 9.61% |
Possibility 3: Grimy torstols | 9.96% |
Possibility 4: Runes | 7.5% |
Possibility 5: Iron ore | 8.47% |
Possibility 6: Coal | 9.17% |
Possibility 7: Rune bars | 9.61% |
Possibility 8: Gems | 9.61% |
Possibility 9: Loop half of a key | 7.94% |
Possibility 10: Tooth half of a key | 6.61% |
Possibility 11: Rune platebody | 5.03% |
Possibility 12: Rune platelegs or plateskirt | 8.47% |
Possibility 13: Dragonstone armour | < 0.01% |
- ^ The runescape wiki lists the probability of receiving a calquat or papaya tree seed at 5:11 (45.45%) each and the probability of receiving a palm tree seed at 1:11 (9%). This data shows a probability of 49.45% for the calquat, 47.25% for the papaya, and 3.30% for the palm tree seed.
Using these probabilities, the expected average profit/loss, per crystal key, when looting the crystal chest is -7,376. (Assuming you will receive whichever of the rune platelegs and rune plateskirt is worth more, and the crystal key is bought at GE price). This is excluding the possibility of receiving a dragonstone armour piece, as this possibility is much too rare to estimate with any acceptable accuracy.
TriviaEdit
- The crystal key chest was reworked on 11 June 2013 with the release of the Triskelion Treasures. Previous old drops, such as receiving 2000 coins and a Spinach roll along with an Uncut dragonstone, were removed, and new ones were added, such as the Dragonstone armour.
