Varrock crossbow

The Varrock Crossbow requires 80 Ranged, and completion of Digsite quest to wield this weapon. The ammunition can be used up to Dragon arrows, and has a special attack: Weaking Arrow. It inflicts 40% more damage, and lowers the target's defence level by 70%. Uses up 30% of the special attack bar. You cannot lower other players attack level as Jagex changed it as many complaints from players, saying that their defence levels are lowered, so the ranger can have an advantage.
