Best For

Groups who want gritty, tactical, and realistic combat in a skill-based percentile system, particularly for historical, mythic, or low-fantasy settings.

Core Mechanic

Roll d100 under your skill percentage. In combat, degree of success vs. opponent determines Special Effects: tactical maneuvers like Disarm, Trip, Bypass Armor, and Bleed. Action Points govern actions per round, damage applies to hit locations.

High

The d100 core rolls under a skill, but combat is where it opens up. Degree of success buys tactical Special Effects like disarm, trip, or bypass armor, tracked against an action-point economy. Magic comes in several full systems, and Passions and Cults add social and devotional rules. It is a deep, interlocking game that rewards study.
