Venom

Venom is a stronger form of poison that players and monsters suffer after they are successfully envenomed. When a target is envenomed, a number appears with a dark green hitsplat () instead of a bright green one ( which indicates poison), indicating the amount of damage the venom has dealt.

Zulrah and its snakelings, Vorkath, araxytes, Cursed Baboons, manticores and spiders in the Ungael laboratory are the only monsters able to inflict venom. Manticores only inflict venom when the Mantimayhem tier 2 or 3 handicap is active. Players are able to inflict venom upon their enemies by using certain weaponry.

Venom damage

Venom damage increases over time, increasing by a value of two for every time it strikes. Damage starts at one hit of 6 per 18 seconds and increases by 2 each time it hits, capping at 20 damage per hit after a little over 2 minutes.

Total venom damage (D₁ or D₂) over time in seconds (T) can be calculated as:

${\begin{aligned}t&=\left\lfloor {\frac {T}{18}}\right\rfloor \\D_{1}(t)&=(t+1)(t+6)&t\in [0,7]\\D_{2}(t)&=20t-36&t\in (7,\infty )\end{aligned}}$

Curing venom

Drinking a dose of any strength of antipoison or using another method of curing poison will convert the venom to regular poison, which starts at the same damage the venom had. To fully cure venom, players can drink another dose of antipoison. If the player is not currently envenomed, one dose of antidote++ will provide immunity to venom for 18-36 seconds.

One dose of anti-venom will completely cure venom and provide immunity for 36-54 seconds. Anti-venom+ provides immunity to venom for three minutes.

Eating a strange fruit will completely cure venom and provide immunity for about 6 seconds. Drinking Guthix rest or eating cooked moonlight antelope reduces venom to poison. Another way to cure venom (or poison) is by leaving your POH.

Like with poison, clicking the hitpoints orb will automatically cure or reduce venom if the player has anything to counter it.

The Serpentine helm, while worn, provides full immunity to being envenomed and poisoned.

The Noxious halberd special attack completely cures venom, at the cost of 50% special attack energy.

Weaponry that can inflict venom

Each of the following weapons have a 1 in 4 chance (25%) to inflict venom on the opponent for every successful attack:

When combined with the Serpentine helmet, all of the above weapons have a 100% chance to inflict venom if the target is a monster.

The Noxious halberd has a 1 in 3 chance (33%) to inflict venom, increased to 50% when combined with the Serpentine helmet.

Notes

When an envenomed monster goes out of combat, the venom timer is paused and the monster becomes immune to venom until it is killed.^[1]
Venom and Poison make use of the same timer mechanic. As such, monsters can not simultaneously be envenomed and poisoned.
Certain monsters have specific mechanics that make use of their venom/poison timers. Monsters such as chickens and cows cannot be poisoned or envenomed as they use the timer mechanic to determine when to lay eggs and moo respectively. This immunity is not shown in their Monster Examine information.^[2]
