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.

Weapon poison++ can be used on daggers, spears, throwing knives, arrows, darts and javelins. One vial will poison one melee weapon or up to 5 projectiles (arrows, throwing knives, darts or javelins) at a time. 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 6 points of poison damage initially; for projectiles, the initial damage is 4.

Production costs
The data in this table is based on the Grand Exchange prices of the Vial of coconut milk, and secondary ingredient(s). It is accurate assuming both items are bought at the Grand Exchange and the resulting potion is sold afterward. (Note: Nightshade is excluded from the calculations as it is untradeable.)
