Immunity to Iocane Powder

Don’t fall victim to one of the classic blunders.

Iocane Powder is a deadly Australian poison, odorless, tasteless and highly soluble, used in The Princess Bride by the hero Westley in his ‘battle of wits to the death’ with Vizzini. Is available in a powder form, which Westley used. Although it takes a few years, the human body is capable of building an immunity to the poison.
