Extreme Cold
Moderate cold: Fortitude DC 12 hourly or 1d4 non-lethal.
Chapter 13: moderate cold (0 to -20 C) requires Fortitude DC 12 each hour; failure deals 1d4 non-lethal cold damage. A character unconscious from non-lethal cold instead takes 1d4 lethal cold damage per hour. Extreme cold (-20 to -50 C) requires Fortitude DC 18 each 10 minutes; failure deals 1d6 lethal cold damage and 1d4 Dexterity damage. Arctic-rated gear halves cold save DCs. Dynar gain +2 to cold Fortitude saves. Environmental cold damage does not heal naturally until the character reaches warmth; a field medkit restores 1d4 points.
