Fox Lichen

A variant of Letharia Vulpina (wolf lichen) which grows where a Kitsune's blood is spilled.

It has powerful magical properties, and is prized by Hunters, as it temporarily incapacitates canine shapeshifters such as Werewolves.

It is also toxic to Kitsune, and can be used to free someone who has been Possessed by a lower rank kitsune, although higher ranks can resist its effects.
