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 owl prowler, a prestige class ideal for rangers, but also suitable for other martial and roguish characters. Owl prowlers hide in the shadows and rely on their acute senses to strike fatal blows at unsuspecting foes. They understand that brute force is useless and that intuition is the key to survival.
