Barbarians of the Path of the Totem Warrior follow codes made by Celtic Pagans or stolen from Native North Americans. For following the codes, they gain powers from a spirit in nature, usually in the form of an animal. They carry totems or fetishes, and though their rages weaken, they gain new powers in exchange.
Though they and the cultures they descend from are called barbarians by many, not many of them are barbaric. Another important note is that barbarians typically follow the codes of cultures they are descended from, so those descended from Mongols will follow the rulings of Mongol culture to gain their powers, and Celts follow their codes to gain their powers.
