Moon Lore (Rank 1)Edit
Using this Gift, the werewolf can learn the phase of the moon that heralded the birth of another. Although it can determine auspice, Moon Lore gives no clue to whether the subject is a werewolf or even if it is supernatural in any way; being born under a waxing gibbous moon means much more to a Garou than it does to a normal human. Any moon-spirit can teach this Gift.
A single success on a Perception + Primal-Urge roll (difficulty 6) is required to determine the moon's phase at the time of the subject's birth; two successes determine whether it was waxing or waning.
