Scent of Running Water (Rank 1) Edit
The Garou can mask her scent completely, making herself virtually impossible to track. A fox-spirit teaches this Gift.
The difficulties of all rolls to track the Garou increase by two. This Gift becomes an innate ability to the Garou who learns it. She need not expend any points or make any rolls. However, the Ragabash may still leave a scent behind if she decides to do so voluntarily (which may be necessary to blend in with wolf packs).
