Dice mechanics

Percentile (d100) checks in Cyberpunk RED

Roll under skill mechanics and difficulty bands.

Explanation

Percentile checks resolve by rolling d100 and succeeding at/under a target value. This mechanic is most directly associated with Call of Cthulhu-style play loops.

At the table (quick loop)
  • Pick Stat + Skill that matches what you’re doing.
  • Roll 1d10, add Stat + Skill, and compare to the DV.
  • Resolve success/failure with concrete changes in the scene (access gained, alarm triggered, target down, etc.).
Example: REF 7 + Handgun 6 + 1d10 vs DV 15: you need 2+ on the d10 to hit.
Examples
Example: skill target

If a system uses percentile checks, roll d100 and succeed at/under the target value.

Example: fail forward

If the clue matters, don't block progress on failure. Trade success for time, noise, or a new complication.

Common mistakes (smallest fix)
  • Mistake: Forgetting difficulty bands. Fix: Use Regular/Hard/Extreme (or your table’s bands) to express stakes quickly.
  • Mistake: Failure stops the investigation. Fix: Fail forward: you still get something, but pay a cost.
