Venom is a detriment and stronger form of poison that players and monsters suffer after they are successfully envenomed. Zulrah and his snakelings are the only monsters able to inflict venom, whilst players are able to inflict venom upon an enemy by using certain equipment.
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 increases over time, increasing by a value of two for every time it strikes.
Damage starts at one hit of 6 per 20 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 five minutes.
The serpentine helm while worn provides full immunity to venom, as well as poison.
Equipment that can inflict venomEdit
Each weapon has a 1 in 4 chance (25%) to envenom the opponent for each a successful attack. The helm has a 1 in 6 chance (16.7%) of envenoming any opponent attacking the wearer, regardless of whether damage is dealt.
