Gnomesbane

Gnomesbane is a black flower that grows in southern Midland and the outer Oclus islands.

Properties
Gnomesbane is a slow-acting poison when consumed by Sylvian races. It is easy to detect its effects and any skilled cleric or clinician can easily cure them, but without them one will suffer a week long fever and perish at its end. It is often used in poisons.

A DC 12 medicine or nature check will allow a player to create a poison out of gnomesbane that will affect Sylvian races. It can be obtained in any black market situation for ~25 gold a unit. It can also be found in the forest north of Ang'hor Wat.
