Characters who suffer minor but troubling injuries, such as stumbling down a slope or running through a cavern in the dark, can suffer from Fatigue rather than suffering actual wounds. This is the hazard to use when characters should be beat up a bit but not truly wounded.
When a character suffers injuries like these he must make a Vigor roll. Those who fail gain a Fatigue level from bumps, bruises, cuts, and scrapes. The Game Master may occasionally allow sure-footed characters to make Agility rolls to avoid this damage instead. Fatigue gained in this way can lead to Exhaustion, but not to being Incapacitated.
Example: Two heroes race down a steep slope to escape the clutches of some angry crocodile cultists. The Game Master decides they trip and suffer Bumps and Bruises if they don’t make Agility rolls. The first succeeds but the second fails and suffers Fatigue for the next 24 hours.
