Cyberpunk RED checks are Stat + Skill + 1d10 vs a Difficulty Value (DV). Your Role Ability defines your specialty, and cyberware adds power at a Humanity cost.
At-the-table steps
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.
