Rank 1 Philodox Gift
The Philodox is able to scent the truth of those she meets, literally sniffing out an individual’s true form. A vulture-spirit teaches this Gift.
System: The Garou can smell Kinfolk or a fellow werewolf automatically; pre-Change werewolves smell like Kin. In all other cases, the player must roll Perception + Primal-Urge (difficulty 6). One success will identify a normal human or animal; two successes will detect a vampire, changeling, demon, mummy, or Fera; four successes are needed to sniff out a mage, ghoul, or fomor. The Imbued register as normal humans to this Gift. Unfamiliar scents aren’t automatically recognized: A Philodox that has never encountered any Rokea might not immediately recognize the scent she detects as “wereshark.”
