Blue dragonhide

Blue dragonhide (aka blue d'hide by tanners) is dropped 100% of the time when a Blue Dragon dies. Players can take it to a tanner and turn it into blue dragon leather for a fee of 20 coins per hide. Players can make blue d'hide armour from the leather using the required level from the Crafting skill. A tanner can be found in Lumbridge just south of the yaks.
