From publisher blurb:
HARP Martial Law - the new road to High Adventure
How do monsters and magic affect weapons, armor, and fighting styles?
Martial Law breaks new ground in the field of fantasy role playing combat rules. Martial Law expands the fast, dramatic combat of HARP (High Adventure Role Playing) Fantasy to include detailed hit location criticals.
Martial Law also includes a section on creating and playing warriors in fantasy settings and cool new moves and equipment for fighters.
Drawing upon years of actual play from the fan base, HARP Martial Law is an enhanced version of the original HARP supplement published in 2004.
