A player taking damage from poison

Poison hitpoints minimap

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 (Poison hitsplat) instead of a red or blue one, indicating the amount of damage the poison has dealt. Poison wears off over time, decreasing by a value of one for every five times it strikes.

For instance, if a player is hit by another player wielding a regular poisoned dagger, they would be hit for 4 damage every minute (four times), then 3 damage every minute (four times), then 2 damage every minute (four times), then 1 damage every minute (four times), and then the poison would be gone.

Some monsters must inflict damage in order to poison a player (snakes, spiders, etc.) while others will inflict poison regardless of damage (Cave slime). 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
  • Default poison and abyssal tentacle: 4, 2
  • Strong poison: 5, 3
  • Super and Karambwan poison: 6, 4
  • Converted venom to poison by drinking any antipoison potion once: 6
  • NPC poison: 8-20

Weapon poisoning Edit

Weapons can be poisoned by weapon poisons made through the Herblore skill. There are several types of weapon poisons which deal progressively more damage. Only spears, arrows, bolts, darts, throwing knives, javelins, daggers, and hastae could be poisoned. The abyssal tentacle can also poison.


  • A player must hit at least 1 or higher with the poisoned weapon to poison their enemy, Each hit 1 or higher with the poisoned weapon will reset the Poisons duration against the enemy you have already poisoned.
  • A weapon poison potion can only be used on 5 thrown objects before running out, e.g. 5 Arrows or 5 Darts.
  • If you poisoned a monster while fighting it, you will not receive experience from the poison damage. Some monsters, such as Wall beasts, Turoths, Waterfiends, and the God Wars Dungeon bosses, are immune to poison.
  • Poison can be removed from weapons with a cleaning cloth, obtained by using Karamja rum with Silk.

Curing poison Edit

Poison can be cured through antidotes in the form of anti-poison potions. Anti-poison potions come in various levels which provide progressively longer immunity to poisoning.

The serpentine helm while worn provides full immunity to poison, as well as venom.
