Weapon poison is a potion made by using dragon scale dust on a kwuarm potion (unf), requiring 60 Herblore, yielding a weapon poison and 137.5 Herblore experience. It can be applied to all metal arrows (including amethyst), normal metal bolts, javelins, darts, and throwing knives, most daggers, spears and hastae as well. Weapon poison can be removed from a weapon with a cleaning cloth.

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

Melee attacks apply poison at 25% chance, where Ranged attacks apply poison at 12.5% chance. Weapon poison initially deals 4 damage when applied using melee attacks, or 2 damage with Ranged attacks. The poison hits every 18 seconds, and if not reapplied to the target, the poison damage will deal 1 less damage every 5 hits until the target is no longer poisoned. Ranged weapons with Weapon poison applied, however, will only hit 2 once before starting to hit 1s. For melee weapons this means a total of 50 damage will be dealt from the poison, whilst for ranged weapons this will only be 7.

You can remove weapon poison from a weapon with a cleaning cloth.

It is a possible reward from the Observatory Quest if the player identifies the Scorpio constellation.

Total poison damage

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

${\begin{aligned}D_{M}(M)&=H\cdot \sum _{n=1}^{M}n=H\cdot {\frac {1}{2}}M(M+1)=2.5\cdot 4(4+1)=50\\D_{R}(M)&=H\cdot \sum _{n=1}^{M-1}n+M=H\cdot {\frac {1}{2}}M(M-1)+M=2.5\cdot 2(2-1)+2=7\end{aligned}}$
