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 adaptive hunter, a prestige class ideal for rangers, but also suitable for other martial or roguish characters. Adaptive hunters are able to tap into their species’ biological memory, making them cunning survivors and dangerous predators. Armed with flexible abilities and skills, they are masters at adapting to every situation.
