Long bone

A Long bone is an item dropped by monsters, which drop big bones 100% of the time, such as Hill giants, Moss giants, Mogres, Fire giants, Trolls, Ogres, etc.

Long bones give 15 experience points when buried, though this course of action is not recommended.

Alternatively, long bones may be sold to Barlak, a cave goblin found in Dorgesh-Kaan for 1000 coins. You will also receive 1500 Construction experience, if your Construction level is 30 or above.
