Way of the Open Hand
A dual-system supplement for Legend of the Five Rings and Rokugan d20, focused on unarmed combat and the martial traditions of Rokugan. It details the history, practices, and paths to enlightenment of the Brotherhood of Shinsei, along with more than twenty martial arts styles associated with the Great Clans and other schools. New rules, feats, abilities, and fighting techniques support campaigns with a stronger martial arts focus and can be adapted to other d20 fantasy settings. The material draws on real-world traditions, Asian mythology, and Rokugani history.
