Storm is an emote unlockable by members using Loyalty points. It is bought from Xuan in Burthorpe for 4000 Loyalty points. When performing the emote, the player levitates upward raising their hands which summons a storm cloud causing a lightning storm above the player.
In certain high places, such as the top of Lumbridge Castle, using this emote will also cause rain to appear.
