From publisher blurb: The Flowing Water Style allows the warrior to use a wide variety of weapon ranging from the bo staff to the Yueng Yang Blade in a style that allows the wielder to effectively make two weapon attacks, disarm foes, feint opponents, and even sunder weapons and armor. This feat style path allows characters to emmulate the effects of other feats that may have limitations based on ability scores or class requirements. The supplement also introduces several new oriental weapons for the Pathfinder game including the Gunbai (war fan), Chin Zi Dao (double weapon), and Sun & Moon Ring.
