| 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 an attribute die and usually a skill die, each sized from d4 to d20 by the character's rating. Read each die separately: 5–9 gives one success, 10–14 two, 15–19 three, and 20 four. A 1 adds a complication even when the other die succeeds. Meet the Referee's required success count or beat an opponent's successes, with extra successes adding Harm or other effects. Each player gets one Nudge per session to shift a single die by one point after the roll. |

| 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 modern occult horror where hunting haunted objects risks eroding their characters' identities. |
| 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. | Harm steps attribute dice down directly, so damage weakens the dice used for later actions. The otherworld called the Gloom drains an attribute step at each scene's start and end unless resisted through sacrifice, weakening the dice needed to escape. Haunted objects called Residues have destruction conditions tied to their emotional origins, turning hunts toward memorials or exposing abuse rather than combat alone. |
| 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 core provides no advancement procedure, leaving the group to decide how skills or abilities improve over a campaign. The colossal beings called Infadha take no Harm from attacks, so ordinary combat cannot defeat them. Several sample Residues are built on suicide, child abuse, and domestic abuse, with safety guidance limited to brief advice during character creation. |
