Iocane

Iocane is one of the deadliest known poisons. It is usually found in a powdered form, and dissolves instantly in most liquids. It has no taste or smell, and is thus close to undetectable. It is also a very swift acting poison, killing in less than a minute.

Despite its deadliness, it is possible, by repeated application of the smallest doses, gradually increasing in size over a course of several years, to develop an immunity to it, although the limits of this immunity have rarely been tested, as only a single individual is known to have developed it.

Iocane originates in Australia, where it is a small but highly valuable part of that nation’s export trade, and a well-known tool of business in its criminal underworld.
