Water’s Gift

Weapon (any), uncommon (requires attunement)

This magic weapon protects you in the harshest of environments. While you have this weapon on your person, you have advantage on any saving throw against exhaustion due to the extreme cold or high altitude. You also deal an extra 1d6 weapon damage with this weapon when attempting to break the ice of non-living icy surfaces. In addition, you and any of your companions within 30 feet of you have advantage on Dexterity (Acrobatics) and Strength (Athletics) skill checks to navigate icy environments. The weapon magically prevents you and any companions within range from freezing to death or being damaged from frostbite.
