Skills in Call of Cthulhu 7th Edition
Skills overview and how checks typically work. Call of Cthulhu 7th Edition is a horror investigation roleplaying game based on H.P. Lovecraft's Cthulhu Mythos. Players take on the roles of Investigators, ordinary people who uncover cosmic horrors beyond human comprehension. As you investigate mysteries, your character's Sanity slowly erodes, skills improve through use, and the line between reality and madness blurs.

If the clue matters, the Keeper can make failure cost time or safety instead of blocking progress. Use Regular/Hard/Extreme to express stakes.
Pick a few skills that match your investigator concept, then rely on teamwork and preparation for the rest.
- Mistake: Rolling without stakes. Fix: Say what success changes and what failure costs before rolling.
- Mistake: Treating failure as ‘nothing happens’. Fix: Fail forward: you still learn something, but pay a cost (time, exposure, resources, harm).
