War Is Hell
This expansion for Contagion Second Edition adds optional rules for portraying the brutality and supernatural strangeness of its dark modern setting. It introduces rules for familiars and homunculi, three rituals—including Compel Celestial, Decode True Name, and Demon Summoning—and new creatures and supernatural forces. The book also includes seven combat maneuvers, such as curbstomp, coup de grace, and dismembering strike, along with ten new feats. Gamemasters can use the material to expand combat, rituals, and character options.
