Dice mechanics
Modifiers in Call of Cthulhu 7th Edition
Bonuses, penalties, and situational adjustments.
Explanation
CoC difficulty often changes the success threshold (Regular/Hard/Extreme). Use that lever before stacking many small modifiers.
Examples
Example: position over +1/-1
Instead of tiny modifiers, change position: better cover, better tools, better information.
Example: keep it consistent
Pick one primary difficulty lever for your table (DV/DC, threshold bands, required successes) and stick to it.
Common mistakes (smallest fix)
- Mistake: Stacking many small modifiers. Fix: Use one clear difficulty lever and keep the decision readable.
- Mistake: Applying modifiers without stakes. Fix: Define what success changes and what failure costs before rolling.
