Roll when the outcome is uncertain and matters. If it’s routine and no one at the table cares about failure, just succeed and move on.
Before rolling, say what success gives you and what failure costs (time, exposure, resources, harm).
- Mistake: Rolling without stakes. Fix: Say what success changes and what failure costs before rolling.
- Mistake: Treating failure as ‘nothing happens’. Fix: Fail forward: you still learn something, but pay a cost (time, exposure, resources, harm).
