Poisons can be delivered many ways. If ingested, its effects occur automatically. If a victim is Shaken or wounded by a bite or weapon coated in poison, he must make an immediate Vigor roll against the type of poison listed on the Poison Effects Table below. If the poison has a modifier associated with it (such as Venomous [-2]), the victim's Vigor roll is modified appropriately.
The Game Master must decide which category is appropriate based on the poison. Most real-world animals are Venomous with only a few falling in the Lethal category. Ghouls might have paralyzing poison in their claws, while spies might use Knockout poison in drinks or gases.
Characters who suffer Paralysis or a Knockout are Incapacitated until they recover.
Treatment: To treat a poisoned victim, the healer can try a Healing roll minus the strength of the poison itself (found in the poison's description). If successful, the victim's life is saved and the poison no longer has any effect–paralyzed victims can move and those rendered unconscious wake.
Each character may only attempt one Healing roll per incident to cure the poison, but another character with Healing may make a second attempt, and so on.
