Endure Elements

Protection from normal environmental hazards.

You can target up to 6 willing creatures. A creature protected by endure elements suffers no harm from being in a hot or cold environment. It automatically succeeds on all saving throws made to resist the effects of Extreme Cold and Extreme Heat weather conditions.* The creature’s equipment is likewise protected. This spell doesn’t provide any protection from fire or cold damage, nor does it protect against other environmental hazards such as smoke, lack of air, and so forth.

*See weather conditions in chapter 5 of the Dungeon Master's Guide (pages 109 to 110).
