A Poisoned Mithril Throwing Dart is a poisonous throwing dart. It is the third-strongest poisonous throwing dart in RuneScape Classic, can be equipped by players with level 20 ranged, and is made by adding weapon poison to a mithril throwing dart. Like all throwing darts, they provide no WeaponAim or WeaponPower, and when they are equipped, they are invisible to other players. However, they provide a significant invisible ranged bonus.
