Core Mechanic

Roll 1d20 and meet or exceed the target supplied by the attack or saving-throw table. Exploration, reactions, thief abilities, doors, and treasure use separate d6 or percentile procedures rather than one universal action rule.

Best For

Groups who want a referee-led, map-and-torch dungeon campaign with low-level adventurers, treasure-driven advancement, tactical table-based combat, and room for improvised rulings.

Highlights

Ten-minute turns make mapping, searching, light, rest, and wandering monsters central expedition pressures. Worked melee and referee-player examples demonstrate combat, formation, secret-door searches, and encounter pacing in context. The included Zenopus dungeon and removable reference tables provide a ready starting site and consolidated table aid.

Considerations

The rulebook covers only the first three character levels and points longer campaigns toward Advanced Dungeons & Dragons. Combat, saving throws, thief abilities, doors, traps, and reactions each use separate procedures instead of one task mechanic. Low hit points, poison, paralysis, and other severe effects can remove characters abruptly, and no current legal complete-core storefront was located.
