Glass Walkers -- who understand the workings of science and spirits alike -- can mystically excite the molecules within metal. Metal heated in such a way can be forged, molded or used to sear flesh. A red-hot crowbar can be a very effective weapon, and heating the exterior of a gasoline tanker can have explosive results. Glass Walkers learn this Gift from fire, earth, or metal elementals.
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.
