Stardust can be mined during the Shooting Stars activity. Shooting stars randomly land anywhere on Gielinor approximately once every two hours.
Players can identify the general area where it will land (Asgarnia, Great Kourend, etc.) by using a telescope in a player-owned house study. Once they have mined a crashed star down to its core, they can exchange the stardust at Dusuri's Star Shop.
The amount of experience per stardust mined varies by the current level of the crashed star.
Free players may acquire stardust, but will not be able to use them as Dusuri's Star Shop is only available to members.
