Fatigue from Environments

Hot, cold, humid, dry, polluted, or irradiated environments can cause fatigue damage, depending on the severity of the surroundings. As with running fatigue, the DV from a harsh environment starts at 1S and increases over time. Unlike running fatigue, if you keel over in a hostile environment the damage doesn’t stop rolling in.  
ENVIRONMENT SEVERITY FATIGUE DAMAGE INTERVAL
Mild 6 hours
Moderate 3 hours
Harsh 60 minutes
Extreme 1 minute (10 Combat Turns)
Deadly 6 seconds (2 Combat Turns)
