A creature that fails the saving throw by 5 or more gains a [[Freeze Injury]]. **Resting In Extreme Cold.** A creature that takes a [[Short Rest|Short]] or [[Long Rest]] while exposed to [[Extreme Cold]] cannot recover [[Hit Point Dice]] and cannot expend Hit Dice to restore their [[HP]]. # During Combat **Taking Cold Damage In Combat.** Whenever a creature takes Cold damage while exposed to Extreme Cold, it must make a saving throw against [[Extreme Cold]], this save can only happen once per turn. # Other Details **Remove Exhaustion Levels.** A creature can remove one Exhaustion level it gained from being exposed to [[Extreme Cold]] by finishing a [[Short Rest]] and succeeding on a DC 10 CON Saving Throw at the end of the [[Short Rest]]. A creature has [[Advantage]] on this saving throw if it spent the [[Short Rest]] near a source of heat. **Automatic Success.** Creatures with [[Resistance]] or [[Immunity]] to Cold damage automatically succeed on the save, as do creatures that are naturally adapted to living in the arctic.
