Shadow of the Rat (Rank 4) Edit
Rats are known for their resilience, persistence, and ruthlessness. Since Rat serves as the Bone Gnawers' tribal totem, Garou of this tribe may learn a great deal about survival under the tutelage of rat-spirits.
The Garou can spend one Gnosis to lower the difficulty of all Stamina rolls (including soak rolls) by 1 for the duration of one scene.
