Poison is perhaps the most common adverse effect that heroes fall victim to. A character who has been poisoned will gradually lose health, often causing death within twenty minutes of the poisoning. Even if the warrior survives the battle in which he is poisoned, the venom remains in his system and does damage with every step that he takes. Time does not cure poison, nor does staying at an Inn. The only remedies for this affliction are the Pure Potion item and the Pure spell.
