Some warriors of the Warhammer world use lethal toxins to envenom their weaponry. The Dark Elf Adepts of Khaine and the Skinks of the steaming jungles of Lustria are the most noted exponents in the use of poisoned weapons.

A warrior with poisoned attacks will wound his target automatically if he scores a 6 when determining whether he hits his opponent in the Shooting or Close Combat phases. Armour saves are taken as normal. Unliving targets (such as war machines) are immune to poison as are some troop types. These are clearly defined in their description.
