Endurance of Heimdall (Rank 5)Edit
This powerful Gift grants the Garou great endurance and hardiness for a time. This Gift is taught by a Boar-spirit.
The Garou spends one Gnosis point and rolls Willpower (difficulty 6). If successful, the Garou's Stamina rating is doubled for the duration of the scene. This will aid Stamina and Soak rolls.
