| Core Mechanic | Roll d100 equal to or below a skill or characteristic. Hard and Extreme tests use half and one-fifth of that rating. Bonus and penalty dice select a better or worse tens digit. Eligible failed skill rolls can be pushed by taking further action, risking a harsher consequence. | Roll 1d6 against the relevant Aspect (Beast, Omen or Trickster, rated 2 to 5): a roll below the Aspect succeeds, a roll equal to it succeeds and earns a Portent, and a roll above it fails. A helping Crow counts the Aspect as 1 higher, to a maximum of 5. When a Crow acts in accordance with its Augury, the player may roll two dice and use either; when it contradicts its Augury, or an Affliction affects the roll, the player rolls two dice and Fate (the GM) chooses which counts. A human may roll 1d6 to resist; if the human's roll matches or is lower than the Crow's, the Crow fails even on a success. |

| Best For | Groups who want clue-driven horror with ordinary investigators and lasting consequences. Suits focused mysteries and campaigns where survival matters more than defeating every threat. | Groups who want a darkly comic one-shot as a flock of crows plotting a human's death, with tables that set up the hunt at the table. |
| Highlights | Pushing a failed roll offers another chance at the goal with a more serious consequence if it fails. Learning Mythos lore reduces maximum Sanity, tying useful knowledge to lasting vulnerability. An Idea roll gets a stalled investigation moving again, with failure putting investigators into danger. | Rolling exactly the Aspect's value earns a Portent, letting the player ask Fate one question answered by a brief, obscure vision. Acting in accordance with a Crow's Augury lets the player pick between two dice, while contradicting it hands that choice to Fate. Fate rolls or chooses with the Crows from d6 tables to set the hunt's victim, motive and complications. |
| Considerations | A major wound can leave an investigator dying, making direct confrontation dangerous. Bouts of madness temporarily place investigator actions under Keeper control. Foot and vehicle chases track relative speed and movement actions, adding a separate procedure to pursuit scenes. | The premise is the flock plotting a human's death, which will not suit groups uncomfortable with murder as the goal. The rules include no death for Crows: a Crow that takes a fourth Affliction leaves the scene or goes unconscious instead. There are no experience, advancement or campaign rules. |
