Weapon poison+

Weapon poison+ is made by mixing a cactus spine followed by red spiders' eggs in a vial of Coconut milk, giving 165 Herblore experience. This requires level 73 Herblore.

Weapon Poison+ can be applied by using the potion after which your character has a chance to poison an opponent. The effect will last 5 minutes and deals between 16% to 32% of your ability damage per hit.

Production costs
This table is based on the Grand Exchange prices of a vial of coconut milk, cactus spine and red spiders' eggs. It is accurate assuming all three items are bought from the Grand Exchange and the Weapon poison+ is sold afterwards.
