A player must speak to various ghosts found throughout RuneScape. They must be spoken to in order. Each will tell you their story, direct you on to the next ghost, and give you a piece of the ghostly robes set. However, a player must have a ring of visibility, which can only be obtained during the Desert Treasure quest, and a ghostspeak amulet, which is obtained during The Restless Ghost quest. Obtaining the robes is necessary to get the full amount of kudos from the Varrock museum.
