Master of Fire (Level 1):
In ancient times, mankind tamed fire, and promised it sustenance in exchange for service. The garou invokes the ancient pact between fire and mankind, and the fire spirits withhold the worst of their damage.
Naturally occurring fire damage is converted to non-aggravated with use of the Gift, and there is some chance, at GM discretion, of supernatural damage (such as from a Charm or Gift) being reduced, for up to half the aggravated damage. It is not negated or changed to non-aggravated, however. It uses a Gnosis either way.
