Warmth

You recite words of a gentle prayer that is of celestial origin, invigorating yourself and those who can hear you with a warmth that radiates from within. Once the prayer is completed, each creature within 5ft of you (including yourself) gain one of the following effects:

• Each creature heals a number of hit points equal to your Proficiency Bonus.
• Each creature gains resistance to cold damage for 1 hour, or until the next time it takes cold damage.
• Each creature that would make its next Death Saving Throw within 1 hour, instead makes the roll with advantage.

Constructs and Undead can't be chosen by this spell, and a creature can't benefit more than once from Warmth per Short or Long Rest.
