Rank 2 Planetary Gift (Hakahe)
This Gift makes the Garou as insubstantial as a shadow and as hard to see. The physical form of the Garou fades to a murky, dark shape that can slither and flow almost anywhere. Although others can use certain Gifts to spot the “shadow” werewolf, anyone wishing to do so must first have a reason to suspect the presence of the Gift’s user. This Gift does not function in bright daylight or in places where no shadows exists — such as a brightly lit room (or a room in total darkness, for that matter).
System: The player spends a point of Willpower and rolls Appearance + Occult (difficulty as assigned by the Storyteller depending on the surroundings). Each success allows the character to assume the shadow-form for one scene (or one combat round); even one success can give the character the advantage of surprise in a battle. No successes means that the Gift fails while a botch throws the characters across the Gauntlet momentarily and does not conceal the Garou upon her return.
