What are the RAW rules for cold weather exposure?
The rules for cold weather in the PHB (p110) indicates that someone with winter gear could basically travel in extremely cold temperatures (anything below 0 degrees Fahrenheit) for weeks, or even months without adverse effects. According to these rules, someone could even sleep right outside in the snow, and, as long as they have food and water, suffer no adverse effects.
Am I missing something?
RAW rulings only, no RAI or DM adjucations please. There are already posts with many opinions on this subject. I am looking for RAW interpretations here.
