First look at 13 Omens, a rules-light horror game

Designed as a study in contrast to Pathfinder, 13 Omens is a rules-light, atmospheric horror game built for one-shot sessions. The designers aimed for character creation and play to be quick, keeping mechanics low so tension stays focused on the story. The game uses a communal bag that begins with eight six-sided dice.

Players draw two dice to resolve challenging actions, and those initial rolls are relatively safe. As play progresses the Host adds 13 Omen dice to the bag; rolling poorly on one of those can mean failed checks, injury, or death. Characters are ordinary people confronting supernatural threats, and the rulebook includes 13 scenarios that follow a three-act structure from prologue to escalating horror.

Each character has ten aspects—five general and five tied to the scenario—many set by Archetype such as a Jock or Band Geek. Players rank aspects, choose gear and perks or flaws that change how many dice they draw, and move through scenes rather than a tactical map.
