Crystal of power

A Crystal of power is built in the Study of a player-owned house. 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 an elemental mystic staff for the price of 1000 runes of the new element. It is not possible to create combination elemental staves this way.
