Curved bone

A curved bone is an item dropped by monsters that drop big bones, such as ice giants, mogres, and warped tortoises. Additionally, these bones may be obtained when looting a zombie impling jar.

Although curved bones can be buried, giving 15 prayer experience, they are not auto-buried when a player has a bonecrusher in their inventory.

Curved bones may be sold to Barlak, a cave goblin found in Dorgesh-Kaan, for 2,000 coins. Players will also receive 2,250 Construction experience if their Construction level is 30 or above. Death to the Dorgeshuun is required to enter Dorgesh-Kaan.
