Temperature

Source GM Core pg. 95 2.0
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.
