Glowing Gauntlets

Wondrous item, rare, (requires attuntement)

These gauntlets can magically absorb a great deal of heat. The wearer of these gauntlets takes no fire damage from handling or using objects of incredible heat, such as a sword affected by a heat metal spell or burning log from a campfire. This protection extends up to 800 degrees celcius, about the temperature of molten brass; however, the gauntlets only cover up to the middle of the wearer's forearms.

Once per short rest as an action the wearer can extend a free hand wearing one of the gauntlets and let out a jet of hot blue fire. All creatures within a 20ft. cone must make a DC 14 dexterity saving throw or take 4d4 fire damage, taking half as much on a successful save. If the gauntlet has been exposed to extreme heat (hotter than 400 degrees celsius, such as open flames) within the last hour the damage die increases from d4 to d8.
