Poison (effect)

Poison affects players (not monsters) by dealing damage over time, even outside of combat. A player becomes poisoned through contact with a poisoned weapon, a trapped object, or a poisonous monster, such as a Poison Spider. Note that it is possible to be poisoned by ranging a poisonous monster. Additionally, the Paralyze Monster prayer does not protect you from getting poisoned. Poison can be cured by dying, or with a cure poison potion or  poison antidote. Although both potions provide protection from poison, antidotes have the benefit of resistance from poison for a longer amount of time.

Weapon poison
Weapons may be turned into a poisoned equivalent by a player with the weapon poison potion. Only certain categories of weapons can be poisoned: daggers, arrows, spears, throwing knives, and darts turning them into the poisoned equivalent. The poisoned weapon is capable of doing additional damage to an enemy slowly over a period of time.

Mechanics of being poisoned
Poison from monsters causes damage around once every 20 seconds (~34 game ticks). It can be stalled by logging out before the 20th second passes. The player will be damaged five times with one value, which then decreases by one, hitting five times with the lower value, and so on. This process can be reset by getting poisoned again.

The chance to be poisoned by a monster is considered to be random, and is not fully understood. There is no specific graphical variation for a poisonous hit splat, and it is shown as the same red hit splat displayed when receiving any other damage. The hit splat displayed when a player receives poison damage is the same color red as any other ordinary damage, however, has graphical variations for types of damage received.

PVP
Players are unable to poison one another via PKing or Duelling.
