Venom is a detriment and stronger form of poison that players and monsters suffer after they are successfully envenomed. Zulrah and his snakelings, as well as Vorkath and the spiders in the Ungael laboratory are the only monsters able to inflict venom, whilst players are able to inflict venom upon an enemy by using certain weaponry.
When a player or monster is envenomed, a number appears with a dark green hitsplat () instead of a green one (which indicates poison), indicating the amount of damage the venom has dealt. 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.
Drinking a dose of any strength of antipoison will convert the venom to regular poison, which starts at 6 damage. To fully cure it, players can drink another dose of antipoison. One dose of anti-venom will also completely cure venom. However, players will not gain immunity to venom, unless a dose of anti-venom+ is taken, which provides immunity to venom for three minutes.
The Serpentine helm while worn provides full immunity to venom, as well as poison.
