Blue dragon masks are a reward from a level 3 (hard) clue scroll. Upon release the value was 20,000,000 coins. This can be worn in the head slot.
Blue Dragon masks came as part of the 4 August2010Update: Elite Treasure Trails and New Rewards, together with other Rewards.
This mask gives no stat bonuses; players wear it to show off they have it or because they like the appearance. If a player used an Orb of oculus and got really close to the Dragon Mask, the orb's view will pass through the mask and would reveal the new facial model for characters.
It was recently revealed that the odds of getting a dragon mask from a treasure trail are lower than 1 in 1,000.
Due to its major popularity, there have been speculations that this will in-turn end up becoming like similar items such as the Party Hat or Santa Hat. This however is not true as Jagex is not ready to discontinue the mask from the scrolls. .
