A blue dragon scale is used to make weapon poison, a great thing to put on daggers or arrows for pvp combat. To make it, first get a blue scale from the Blue dragons in Taverley dungeon. Next, take a pestle and mortar and use it on a blue dragon scale to make a ground blue dragon scale. Put it in a vial with water mixed with a kwuarm. Then take the weapon poison and apply it to a dagger/arrows to make a poisoned dagger or 5 poisoned arrows.
