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.
Skills describe trained competence. Use this page to quickly understand what the skill list covers and how to pick priorities.
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.
