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

Weapon poison deals 4 damage every 15 seconds. If it is not reapplied to the target, the poison deals 1 less damage with each passing minute until the target is no longer poisoned when the damage would be 0.

Weapon poison can be removed from weapons with a cleaning cloth.
