Survivor (Rank 5) Edit
This Gift confers temporary immunity to many environmental factors. The Garou has no need of food, water or sleep, and she does not suffer from temperature extremes. She is also immune to natural diseases and poisons. Wyrm toxins will still affect her, but at half their normal potency.
The player spends one Gnosis and rolls Stamina + Survival (difficulty 7). The effects last for one day per success. By spending a second Gnosis point, the Bone Gnawer can gain three extra points of Stamina, and he suffers no wound penalties, but the Gift will expire prematurely after 10 rounds of full combat. The Garou must sleep for at least eight hours when the Gift wears off, and he awakens ravenously hungry.
