Scent of the True Form (Rank 1)[]
This Gift allows the Garou to determine the true nature of a person. This information is conveyed as an olfactory sensation - it is actually a scent of the target's natural form. Any spirit servant of Gaia can teach this Gift.
System[]
The Garou can tell automatically when someone is a werewolf; anything else requires a Perception + Primal-Urge roll. It takes two successes to detect Vampires, faeries or other shapeshifters as such, and it takes four to detect fomori or Mages.
Other terms for this gift are: Eyes of the Soul, Sight of the True Form
