Frostbite (Patreon)

Wondrous item, legendary (requires attunement)

A pair of gauntlets adorned with the twin skulls of white dragons that constantly emit a cold rolling fog from jagged shards of ice. While wearing these gauntlets your unarmed strikes deal an additional 1d6 cold damage and gain a +3 bonus to attack and damage rolls. While attuned to these gauntlets you are immune to cold damage and are vulnerable to fire damage.

Heat Death. If you damage a living creature 3 times in one round of combat with unarmed strikes while wearing these gauntlets, the target must make a DC 18 Constitution saving throw. On a failed save the creature takes an additional 3d6 necrotic damage and you heal for the amount of damage dealt. On a successful save the creature takes half as much damage and you heal for the amount of damage dealt.

Permafrost. You can use your action to blast the battlefield with sub-zero temperatures as a 40-foot cone of ice and sleet erupts from your hands. Each creature in the area must make a DC 18 Constitution saving throw. On a failed save, the target takes 6d8 cold damage and its speed is halved, it takes a −2 penalty to AC and Dexterity saving throws, and it can’t use reactions. On its turn, it can use either an action or a bonus action, not both. Regardless of the creature’s abilities or magic items, it can’t make more than one melee or ranged attack during its turn. On a successful save the target only takes half as much damage and does not suffer the additional effects. A creature that failed may attempt another saving throw at the end of each of its turns to end the effect. Once you use this feature you can't use it again until you finish a long rest.

Curse. While attuned to these gauntlets you appear undead to all outward inspection and to spells used to determine the target's status as your body temperature is always below freezing. If you die while attuned to these gauntlets your body shatters into icy dust. You can only be brought back to life by a True Resurrection spell.

Cold to the touch and frightening to behold, few have ever laid eyes or hands upon these frigid gauntlets. To bear them is to accept the harshness of biting cold and frosty death with every step you take, to become an avatar of sheer nature. Mercilessly stealing warmth from those who seek it, taking life from those who hold tight, robbing any sense of comfort and hope from its foes, Frostbite will snatch all from those it touches.
