Kiss of Helios (Rank 5) Edit
The Ahroun can invoke the sun's power to become completely immune to the damaging effects of fire. Additionally, the Ahroun may ignite any portion of his body and keep it burning for extended periods. Most commonly the Garou will light his mane during rituals, but he can also ignite his claws or mouth without ill effect. A fire elemental or a sun-spirit teaches this Gift.
The player spends one Gnosis. For the rest of the scene, the Ahroun cannot be harmed by any natural forms of fire, up to and including molten lava. Artificial fires (napalm, gas fires, etc.) do one-quarter damage, and they are treated as bashing damage. The Garou does two additional dice of aggravated damage if he attacks with blazing fists, claws or fangs. The effects last for one scene.
