Agathys’ Armor

This armor has a dense layer of frost covering it, is cold to the touch, and always seems to have an air of cold that can be seen flowing off it. While wearing this armor it grants you a number of temporary hit points daily at dawn depending on its rarity. While you have these hit points, if a creature hits you with a melee attack the creature takes cold damage depending on the rarity of the armor. When the temporary hit points are gone the ice surrounding the armor seems to melt away.
