|A curved Construction bone.|
A curved bone is an item dropped by any monster that drop big bones, such as fire giants, Hill Giants, ice giants, Ogres, lizardman shamans, moss giants, Cave Horrors, Suqahs, Cyclops and mogres. The curved bone is dropped at a rate of 1/5,000.
Curved bones can be buried, and doing so grants 15 Prayer experience. However, burying curved bones is not recommended as they can 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. Completion of the Death to the Dorgeshuun quest is required to enter Dorgesh-Kaan.
