A Poisoned Mithril Throwing Dart is a poisonous throwing dart. It is the third-strongest poisonous throwing dart in RuneScape Classic, and is made by adding weapon poison to a mithril throwing dart. It has no requirements to equip it, which may be a glitch, as the non-poisoned version requires level 15 Ranged to equip.
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.
