Keeping campaign notes in Call of Cthulhu 7th Edition
Keep sessions, characters, and notes in one place so your table stays aligned. Use the links below to apply the workflow in Call of Cthulhu 7th Edition and keep it consistent across sessions.
Workflow (do this first)
- Create the campaign in one tool, single source of truth for the table.
- After each session: one-paragraph recap plus any rules calls the GM made.
- NPC log: name, faction, motivation, one line each is enough to keep continuity.
- Tag scenes with the characters present so you can search by player or PC later.
Call of Cthulhu uses percentile skills: roll d100 and succeed if you roll at or under your skill. Difficulty often shifts the threshold (Regular/Hard/Extreme) and Sanity loss is a core pressure loop.
Key facts
- Percentile skill system: Roll d100, succeed if equal to or below skill rating
- 8 Characteristics: STR, CON, POW, DEX, APP, SIZ, INT, EDU (plus Luck)
- Occupation system: Each occupation grants skill bonuses and Credit Rating range
- Sanity mechanics: Starts at POW, maximum reduced by Cthulhu Mythos exposure
- Skill improvement: Mark skills during play, improve after sessions
- Luck: Spend after a roll, point for point, to turn a failure into a success; can't be used on Sanity, damage, Luck rolls, or pushed rolls
Common mistakes
- Mistake: Notes in a Discord chat nobody can find next week. Fix: Persistent campaign space, searchable, ordered by session, linked to characters.
- Mistake: Per-player notes that don’t share. Fix: One shared timeline; private side-notes are fine, but the canonical recap is communal.
Context (system overview)
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.
