From publisher blurb:
Let slip the hounds of war!
A tireless warrior, using an almost precognitive understanding of battles, the stalker hunts his prey with the help of advanced martial disciplines and deadly maneuvers. Included in this book is the complete maneuver combat system, the stalker base class, five martial disciplines with hundreds of strikes, counters, boosts and stances, and new feats!
Path of War is a series of releases focused on a maneuver-based combat system, with the stalker being the first class to be released.
