Tomb Herald

From PathfinderWiki

Tomb Herald is a unique sort of Bramble that grows in most of Avistan's temperate forests and can only be found growing nears burial grounds of some description, it also has a unique property. It is unique in the effect it has on bugbears, when eaten (an unpleasant experience to say the least) it enhances their sense of smell somewhat, when the brambles are fermented into a spirit known as Bramble-Sick Brandy the effect is increased many time over giving them a far more acute sense of smell and thus making them more ferocious hunters.1
