Long bone

A long bone is a non-tradeable bone dropped by monsters that drop big bones, such as giants, ogres, and trolls.

Uses
The long bone's primary use is to be sold to Barlak, a Dorgesh-Kaan cave goblin, for 1,000 coins and 1,500 Construction experience. This requires completion of the quest Death to the Dorgeshuun, level 30 Construction, and the purchase of a player-owned house. Note that during some parts of the quest, The Chosen Commander, players will not be able to sell long bones to Barlak. After the quest is completed, Barlak will be interested in purchasing items again.

Long bones can also be buried and give the player 15 Prayer experience, the same as big bones. This is not recommended, and when a player attempts to bury them, a warning tells the player that "someone" might be willing to buy it; this does not appear if used in prayer via other means. Long bones can also be used on an altar in a player-owned house, used at the Ectofuntus or cremated. In any case, the Prayer experience bonuses apply as if the player had used big bones.

Obtaining long bones
Although there are many monsters that drop long bones, they are fairly rare. There are a few common ways that players obtain long bones. Hill giants and moss giants are the most commonly killed monsters because they are abundant, have a low combat level, and have a decent drop table for profit on the side. Desert Lizards can also be efficiently killed because of their low combat level, especially when using a stab weapon. Some players find long bones by killing river trolls and rock golems in the Enchanted Valley. This requires partial completion of the quest Fairy Tale II - Cure a Queen.
