The dragon knife is the most powerful throwing knife in the game. It requires 60 Ranged to use. The only place that sells this is the Ranging Guild for 900 coins each. The dragon knife has a special attack called Sociopath. The special attack uses 50% of the special attack bar. When used in PvP combat it reduces the target's magic level by the amount of damage done so if it does 80 damage it will take 8 levels off of the targets magic level. When used on a monster in combat it reduces the damage of any enemy that uses magic by 20%
