# Weapon poison(++)

Weapon poison(++), also known as super weapon poison, is made by mixing cave nightshade and poison ivy berries in a vial of coconut milk, giving 190 Herblore experience. It requires level 82 Herblore and is currently the strongest standard weapon poison in Old School Runescape.

Melee attacks apply poison at 25% chance, where Ranged attacks apply poison at 12.5% chance. Weapon poison(++) deals 6 damage (4 damage with ranged weapons) every 18 seconds. If it is not reapplied to the target, the poison deals 1 less damage every 5 hits until the target is no longer poisoned. Ranged weapons with Weapon poison(++) applied, however, will only hit 4 once before starting to hit 3s. For melee weapons this means a total of 105 damage will be dealt from the poison, whilst for range weapons this will only be 34.

A single vial of weapon poison can poison only 5 bolts, javelins, darts, or throwing knives. This makes poisoning a substantial amount of ammo quite costly.

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

## Total Poison damage

Total Poison damage (Melee: DM and Ranged: DR) is calculated by the sum of all numbers (n) up to the max hit (M), times the amount of hits per number (H=5).

{\displaystyle {\begin{aligned}D_{M}(M)&=H\cdot \sum _{n=1}^{M}n=H\cdot {\frac {1}{2}}M(M+1)=2.5\cdot 6(6+1)=105\\D_{R}(M)&=H\cdot \sum _{n=1}^{M-1}n+M=H\cdot {\frac {1}{2}}M(M-1)+M=2.5\cdot 4(4-1)+4=34\end{aligned}}}

In conclusion: To defeat something with only poison, melee provides just over double the amount of poison damage compared to ranged poison damage and additionally has double the chance to be applied (1/4 vs 1/8).
