Weapon Poison

Weapon poison requires level 60 Herblore to make. It is made by mixing clean kwuarm and Dragon scale dust in a vial of water, giving 137.5 Herblore experience. It is dropped by ankous and shadow warriors. It also can be a reward from Observatory Quest.

Weapon Poison can be used, after which the player will gain the ability to poison an opponent. The poison effect lasts for 1 minute before another dose is applied for the poisoning effect to continue. This potion has the same accuracy as + and ++.
