Temperature

Often, temperature doesn't impose enough of a mechanical effect to worry about beyond describing the clothing the characters need to wear to be comfortable. Particularly hot and cold weather can make creatures fatigued more quickly during overland travel and can cause damage if harsh enough, as shown in the Temperature Effects table below. Appropriate cold-weather gear can negate the damage from severe cold or reduce the damage from extreme cold to that of particularly severe cold. ### Temperature Effects Category Temperature Fatigue Damage Incredible cold –80°F or colder 2 hours Moderate cold every minute Extreme cold –79°F to –20°F 4 hours Minor cold every 10 minutes Severe cold –21°F to 12°F 4 hours Minor cold every hour Mild cold 13°F to 32°F 4 hours None Normal 33°F to 94°F 8 hours None Mild heat 95°F to 104°F 4 hours None Severe heat 105°F to 114°F 4 hours Minor fire every hour Extreme heat 115°F to 139°F 4 hours Minor fire every 10 minutes Incredible heat 140°F or warmer 2 hours Moderate fire every minute Adjust temperatures down by 15° in areas of high humidity.
