Crystal chest

The crystal 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 by using a loop half of a key with a tooth half of a key (or vice versa) or by clicking on one and 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 chests are included among the actions that can provide a money tree seed, regardless of the reward received from the chest.

Rewards possibilities[edit | edit source]

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. Unless otherwise specified, all possibilities give all of the listed rewards when obtained. Wearing a ring of wealth or luck of the dwarves will increase your chances of getting a better drop.

Probabilities[edit | edit source]

Taverley chest[edit | edit source]

The probabilities in this section are an estimation based on the data of 2000 crystal chest loots on the Taverley chest, while wearing a luck of the dwarves.
Possibility Percentage
Possibility 1: Fruit tree seed 5.9%[1]
Possibility 2: Lantadyme seeds 8.7%
Possibility 3: Grimy torstols 9.9%
Possibility 4: Runes 9.3%
Possibility 5: Iron stone spirits 9.5%
Possibility 6: Coal stone spirits 9.3%
Possibility 7: Runite stone spirits 7.9%
Possibility 8: Gems 8.4%
Possibility 9: Loop half of a key 7.6%
Possibility 10: Tooth half of a key 7.7%
Possibility 11: Huge plated rune salvage 6.2%
Possibility 12: Large plated rune salvage 9.9%
Possibility 13: Dragonstone armour < 0.01%
Secondary: Money tree seed 0.15%[2]
  1. ^ The official probability of receiving a calquat or papaya tree seed is 5:11 (45.45%) each and the probability of receiving a palm tree seed is 1:11 (9%). This data shows a probability of 52.14% for the calquat, 39.31% for the papaya, and 8.55% for the palm tree seed.
  2. ^ Requires 99 Farming. Secondary reward.

Using these probabilities, the expected average profit/loss, per crystal key, when looting the crystal chest is 13,737. This is excluding the possibility of receiving a dragonstone armour piece, as this possibility is much too rare to estimate with any acceptable accuracy. This also excludes the money tree seeds, as this is not a direct reward from the chest and does not replace any of the other rewards.

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%
Secondary: Money tree seed 0.15%[prif 1]
  1. ^ Requires 99 Farming. Secondary reward.

Using these probabilities, the expected average profit/loss, per crystal key, when looting the crystal chest is 9,616. Assuming the crystal key is bought at GE price and the luck of the dwarves ring is worn.

This excludes:

  • crystal tree blossom, corrupted ore and crystal motherlode shard, as they do not have an intrinsic value.
  • dragonstone armour piece, as this possibility is much too rare to estimate with any acceptable accuracy
  • money tree seed, as this is not a direct reward from the chest and does not replace any of the other rewards.


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.
