To fish using a karambwan vessel, players must first learn from Lubufu, an aged fisherman that lives near Brimhaven. Prior to finishing the quest, Karambwan can be caught only near Lubufu. After finishing it, however, this spot becomes inaccessible, and the vessel can be used only in eastern Karamja, near a fairy ring (combination ). For a vessel to work, a raw karambwanji must first be placed inside. There is a chance that the karambwan will steal the karambwanji without being caught.
