From publisher blurb:
Warriors of the Wild is a fantasy d20 product line designed for both players and game masters. It offers well-balanced and thoroughly play-tested classes constructed around various animal, natural, and tribal themes. These classes are perfect for any combat-heavy game, be it in dungeons, cities, the wilderness, or other planes.
This product features the juggernaut, a prestige class ideal for barbarians and fighters, but also suitable for other martial characters. Juggernauts are warriors with a visceral need to plow through opponents. Their sheer physical strength allows them to charge or overrun their foes in any situation, and their great resolve makes them unstoppable.
