High pressure zones cause Fortitude saves (DC 15 moderate to 20 crushing) each hour or take 1d6 damage and gain Fatigued/Exhausted.
High pressure zones are areas with extreme pressure -- a deep-sea planet, a crushing chamber, or a ship under high-G. The zone is divided into tiers based on pressure: moderate (DC 15), severe (DC 18), and crushing (DC 20). At each interval (1 hour for ambient zones, 10 minutes for direct exposure), characters inside must make a Fortitude save against the zone's DC. A failed save deals 1d6 damage; moderate zones impose Fatigued, while severe and crushing zones impose Exhausted. Characters wearing pressure suits gain +4 resistance to these saves.
