The animation of a crystal of power once constructed.
A crystal of power can be built in the Crystal ball space of the Study in a player-owned house. It requires 66 Construction to build and when built, it gives 890 experience. The player must have a hammer and a saw in their inventory to build it.
Crystals of power can change the element of a basic elemental staff for free, an elemental battlestaff for the price of 100 runes of the new element (air, water, fire, earth), or a mystic staff for the price of 1000 runes of the new element. Players cannot create combination elemental staves this way, nor can they change combination elemental staves into single-element staves.
- Even though this piece of furniture cannot be made into a flatpack, the Grand Exchange reveals a flatpackable version of it (). This may be the result of Jagex deciding that these items should not be made flatpackable for unknown reasons, but did not remove the code for the items before launch.
