Best ForInvestigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots.Groups who want fast, brutal pirate adventures with a doom-metal aesthetic — ship combat, cursed treasure, and a world spiraling toward annihilation.
HighlightsSanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby.Simple rules, ship combat is fast-paced, Devil's Luck creates drama, fully Mörk Borg compatible, extensive random tables for pirate adventures
ConsiderationsChase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaignsClass balance varies significantly, core book layout prioritizes style over reference usability, ship combat rules are lighter than expected, random character generation limits player investment
