Editing All Exiles Say They Were Kings (section)

===Weather===
Heat:
Whenever the temperature is 80-99 degrees F, PCs exposed to the heat must drink double the normal amount of water per day (two gallons instead of one). After one hour of not drinking water, PCs must make Con saving throws as per the Extreme Heat rule (see below).

Extreme Heat:
When the temperature is at or above 100 degrees Fahrenheit, PCs exposed to the heat, even if drinking double rations of water, must succeed on a Con saving throw at the end of each hour or gain one level of exhaustion. The DC is 5 for the first hour and increases by 1 for each additional hour. PCs wearing medium or heavy armor, or who are clad in heavy clothing, have disadvantage on the saving throw. Not drinking double rations of water in Extreme Heat causes an automatic gain of one level of Exhaustion every four hours.

Cold:
Whenever the temperature is 33-59 degrees F, PCs exposed to the cold must succeed on a DC 10 Con saving throw at the end of each hour or gain one level of exhaustion. PCs wearing cold weather gear (thick coats, gloves, and the like) or sleeping in bedrolls automatically succeed on the saving throw.

Extreme Cold:
Whenever the temperature is at or below 32 degrees F, a creature exposed to the cold must succeed on a DC 20 Con saving throw at the end of each hour or gain one level of exhaustion. PCs wearing cold weather gear or sleeping in bedrolls must succeed on a DC 10 Con saving throw at the end of each hour. PCs in a bedroll and in a tent/shelter automatically succeed on the saving throw.

Precipitation:
If the weather is Cold and it’s raining or snowing, PCs must succeed on a DC 5 Con saving throw at the end of each four hour period or gain one level of Exhaustion. If the PC is not wearing cold weather gear, they have disadvantage on the saving throw.

If a PC attempts a Long Rest in the rain without a tent/shelter, they regain only one quarter of their spent Hit Dice (minimum of one die). If they have any levels of Exhaustion, the rest doesn’t reduce their Exhaustion level.
