Might of Thor (Rank 3) Edit
The Garou can increase his strength tremendously, the better to slay his foes. A wolf-spirit teaches this Gift.
The player spends one Gnosis and one Rage, then rolls Willpower (difficulty 8). The Garou's Strength doubles for one turn per success. After the Gift wears off, the Get is weakened considerably (Physical Attributes are considered 1, and Willpower is halved) until he can rest for at least one hour.
Other terms for this gift are: Might of the Kings, Strength of the Crashing Waves
