Extreme Heat
Moderate heat: Fortitude DC 12 each 10 minutes or 1d4 non-lethal and fatigue.
Chapter 13: moderate heat (40 to 60 C) requires Fortitude DC 12 each 10 minutes; failure deals 1d4 non-lethal heat damage and fatigue until cooled. Extreme heat (60 to 100 C) requires Fortitude DC 18 each round; failure deals 1d6 lethal fire damage. Metal armour adds +1 damage per die. Inferno (above 100 C) requires Fortitude DC 22 each round and deals 3d6 lethal fire damage, halved on success. Even powered frames cook occupants after 1d4+2 rounds. Heat-resistant gear halves heat save DCs.
