# Poison

Not to be confused with Venom.
A player taking damage from poison

Poison is a detriment that players and monsters suffer when they are attacked by a poisonous weapon. Many NPCs are able to inflict poison. Players can use poisonous weapons or the smoke set of spells from the Ancient Magicks to cause their target(s) to become poisoned. The maximum damage from this can range from 1 to over 20 depending on the type of poison.

When a player or monster is poisoned, a number appears with a green hitsplat () instead of a red or blue one, indicating the amount of damage the poison has dealt. The victim is then damaged by this poison once every 18 seconds unless it is cured or it wears off. Poison wears off over time, decreasing by a value of one after every 5 hits. Poison doesn't do damage (or wear off) when a player has an interface open. It will hit once immediately after the interface is closed, and continue damaging the player every 18 seconds after that (30 game ticks).

Monsters that can inflict poison may do so regardless of whether or not they inflict any damage, even if protection prayers are used. Player inflicted poison does need to deal damage to apply.

The list of poisons in terms of deadliness are as such:

• Weak thieving poison by opening some thieving chests: 1-2
• Smoke spells: 2, 4 (Rush/Burst and Blitz/Barrage respectively)
• Various weapon poisoning (see below section): 2-6
• Converted venom to poison by drinking any antipoison potion once: 6-20 (the same amount of damage the venom did)
• NPC poison: (varies) 6-20. The aggressive Tribesmen of Karamja, for example, have poison starting at 11.

## Curing poison

Poison can be cured through antidotes in the form of anti-poison potions. Anti-poison potions come in various levels, providing progressively longer immunity to becoming poisoned in addition to curing it. Players who are poisoned can use one of the following remedies or simply left-click their Hitpoints orb on the minimap and their character will automatically use a remedy that they have. Just like how poison does not damage the player with an interface opened, the antipoison timer will not go down until the interface is closed.

## Weapon poisoning (members only)

Members can inflict poison by using weapon poisons made through the Herblore skill on certain weapons. There are several types of weapon poisons, which deal progressively more damage. Only spears, hastae, daggers, arrows, bolts, darts, throwing knives, and javelins can be poisoned. The abyssal tentacle and Emerald bolts (e) are also capable of poisoning players. A weapon poison potion can only be used on five thrown objects before running out (e.g. 5 arrows or 5 darts). Poison can be removed from weapons with a cleaning cloth, obtained by using Karamja rum with silk or by purchasing it directly from Tamayu after completing Tai Bwo Wannai Trio.

A player must deal non-zero damage with the poisoned weapon to have a chance at poisoning their enemy. The chances of inflicting poison are 1/4 for melee and 1/8 for ranged.[1]

1. Jagex. Mod Ash's Twitter account. 5 July 2017. Mod Ash: "1/4 for melee, 1/8 for ranged. [Poison chance is] not material-dependent. Damage must be non-zero."
2. Can only be applied to spears and hastae.

The total poison damage can be calculated by the sum of all numbers up to the max hit, times the amount of hits per number (4, per minute).

${\displaystyle Total=4*\sum _{n=1}^{max}n}$

## Notes

• The poison's duration can be reset while the enemy is poisoned with the same (if not lower) chance as on an unpoisoned enemy.
• If you poisoned a monster while fighting it, you will not receive experience from the poison damage (you will receive full Slayer experience, however, even if the poison applied wasn't yours).
• Some monsters, such as wall beasts, turoths, waterfiends, and the God Wars Dungeon bosses, are immune to poison.
• Poison interrupts some actions, including most skilling actions (but not Woodcutting or Fishing) and the home and minigame teleports. Poison does not interrupt combat in any way.
• If a monster that is poisoned by a player loses sight of the player (ie. the player walks outside its aggression zone), or the player is attacked by another monster in single-way combat, the effect of poison is immediately removed from the monster.
