Crystal key detail.png

The crystal key is used to open one of two crystal chests; one is located inside Ivy Sophista's house in Taverley, the other in the Iorwerth Hall in Prifddinas which has an improved drop table in comparison to the chest in Taverley.

It is created by combining a tooth half of a key with a loop half of a key, displaying the message "You join the two halves of the key together." Doing so will grant you 10 Crafting experience. The crystal key can only be used on the chest once. After it is used, it disappears.

Tooth and loop halves can be obtained as rewards from Barrows, the Evil Tree event, the Gnome Restaurant activity, Managing Miscellania, as well as burning Vyrewatch corpses. Luck enhancers increase the chance for halves to be dropped by monsters who have access to the rare drop table.

Prifddinas crystal chest[edit | edit source]

Using the crystal key in Prifddinas with a ring of wealth can prove useful, as all drops either give a small negative, or larger positive trade, and that excludes any Corrupted ore, Crystal tree blossom or Crystal motherlode shard you may find. You may also be very lucky and get a piece of Dragonstone armour, easily making the effort worthwhile.
