Weapon poison++

Weapon Poison++ (or Super strong weapon poison) is made by mixing nightshade and poison ivy berries in a vial of coconut milk, giving 190 Herblore experience. It requires level 82 Herblore. Note that a herblore level is not required to apply weapon poison to weapons.

Weapon poison++ can be used on daggers, spears, throwing knives, arrows, bolts, hastae, darts and javelins. One vial will poison one melee weapon or up to 5 projectiles (arrows, throwing knives, darts or javelins) at a time. It can also be used on the Keris dagger. Once a weapon has been poisoned by Weapon poison++, (p++) will be suffixed after its name. Players poisoned by a dagger or spear poisoned with Weapon poison++ are dealt 68 points of poison damage initially; for projectiles, the initial damage is 58. The poison damage decreases by two with each hit, until it hits for 10 life points, at which point it wears off.


 * Poison on the weapon can be removed by using Karamjan rum on a piece of silk to make a cleaning cloth. Then the cleaning cloth can be used on the weapon to remove the poison.

Production costs
This table is based on the Grand Exchange prices of a vial of coconut milk and poison ivy berries (cave nightshade cannot be traded or sold on the Grand Exchange). It is accurate assuming the two items are bought from the Grand Exchange and the Weapon poison++ is sold afterwards.

Trivia
