Poisons come in a wide variety of effects as noted in the Traps section (p.226). Different poisons are administered in different ways—by skin contact, blood injury, inhalation, and/or ingestion (GM’s call). Applying poison to a weapon takes an action and remains until a strike is delivered or one minute passes (at which time the poison has either run off the blade or become inert after exposure to air). The GM decides which poisons (if any) are available for sale on a case-by-case basis.
