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 district. 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 generally more profitable to sell the key than to use it. The key is used once and disappears upon usage.

The chest loot always includes an uncut dragonstone, together with a random reward generated from 13 possible reward tables.

Probabilities[edit | edit source]
Taverley chest[edit | edit source]
- The probabilities in this section are an estimation based on the data of 1000 crystal chest loots on the Taverley chest, while wearing a luck of the dwarves.
Possibility | Percentage |
---|---|
Possibility 1: Fruit tree seed | 6.4%^{[notes 1]} |
Possibility 2: Lantadyme seeds | 7.9% |
Possibility 3: Grimy torstols | 9.4% |
Possibility 4: Runes | 10% |
Possibility 5: Iron stone spirits | 9.1% |
Possibility 6: Coal stone spirits | 9.8% |
Possibility 7: Runite stone spirits | 9.4% |
Possibility 8: Gems | 8.3% |
Possibility 9: Loop half of a key | 7.4% |
Possibility 10: Tooth half of a key | 6.8% |
Possibility 11: Huge plated rune salvage | 7.2% |
Possibility 12: Large plated rune salvage | 8.3% |
Possibility 13: Dragonstone armour | < 0.01% |
- ^ The official 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 48.45% for the calquat, 42.18% for the papaya, and 9.37% for the palm tree seed.
Using these probabilities, the expected average profit/loss, per crystal key, when looting the crystal chest is 13,132. This is excluding the possibility of receiving a dragonstone armour piece, as this possibility is much too rare to estimate with any acceptable accuracy.
Prifddinas chest[edit | edit source]
- The probabilities in this section are an estimation based on the data of 20,000 loots of the Prifddinas crystal chest while wearing luck of the dwarves. The loot from the Prifddinas chest is not affected by the Voice of Seren.^{[1]}
Possibility | Percentage |
---|---|
Possibility 1: Tree seeds | 7.59% |
Possibility 2: Herb seeds | 7.555% |
Possibility 3: Grimy lantadymes | 4.47% |
Possibility 4: Talismans | 7.545% |
Possibility 5: Huge bladed rune salvages | 6.00% |
Possibility 6: Coal stone spirits and Adamantite stone spirits | 10.36% |
Possibility 7: Runite stone spirits | 9.455% |
Possibility 8: Gems | 9.525% |
Possibility 9: Loop half of a key | 9.30% |
Possibility 10: Tooth half of a key | 9.045% |
Possibility 11: Large plated rune salvage and Medium plated rune salvage | 8.81% |
Possibility 12: Large plated rune salvage | 10.34% |
Possibility 13: Dragonstone armour | < 0.01% |
Using these probabilities, the expected average profit/loss, per crystal key, when looting the crystal chest is 8,504. Assuming the crystal key is bought at GE price and the luck of the dwarves ring is worn. This is excluding the possibility of receiving a dragonstone armour piece, as this possibility is much too rare to estimate with any acceptable accuracy.
Estimate probabilities for non-guaranteed loot are:
- 17.785% chance of crystal motherlode shard when rolling possibility 9 or 10. This assumes that possibility 9 and 10 yield the same chance for crystal motherlode shards.
- 8.675% chance of receiving elder seed when rolling possibility 1.
- 63.385% chance of receiving papaya tree seed when rolling possibility 1.
- 27.94% chance of receiving yew seed when rolling possibility 1.
- 20.39% chance of receiving dwarf weed seed when rolling possibility 2.
- 79.61% chance of receiving torstol seed when rolling possibility 2.
Trivia[edit | edit source]
- The crystal key chest was reworked on 11 June 2013 with the release of the Triskelion Treasures. Previous old drops, such as receiving 2,000 coins and a Spinach roll along with an Uncut dragonstone, were removed, and new ones were added, such as the Dragonstone armour.
- The estimated dragonstone armour possibility chance is about 0.0147%.
