Martial Arts Mayhem, Volume Two
A modern d20 System martial arts supplement that can be used on its own or alongside a first volume. It adds new martial arts schools, feats, secret techniques, and rules for martial arts weapons, including styles that incorporate psionics or magic. Three campaign models with nonplayer characters provide additional material for running martial arts-focused campaigns. Optional rules expand character and combat choices while maintaining the balance between firearms and martial arts in d20 Modern.
