Potbelly Plate

Armor (breastplate, half plate, or plate), uncommon (requires attunement)

This armor looks like a potbelly stove, complete with an oven door. While wearing the armor, you emit a gentle glow (as if from a bullseye lantern) and a magical warmth: you and other creatures within 10 feet of you ignore the effects of extreme cold. The armor is also immune to the heat metal spell. Inside the armor is a special demiplane that can only contain raw ingredients and prepared foods (and the cookware they're plated on; GM's discretion). Inside the demiplane, the food is cooked and kept at a perfectly warm temperature of your choice. You can use an action to open the oven door and either place or retrieve something inside the space. The demiplane is a 3-foot cube. Anything placed inside the demiplane that doesn't belong causes you to have an upset stomach for 1d4 hours and is singed and forcefully ejected from the oven.

The armor has 3 charges and regains 1d3 expended charges daily at dawn. While wearing the armor, you can use an action to expend 1 of its charges to cast the burning hands spell from the armor (save DC 13), even if you don't have any hands free (the spell erupts from the oven door). A beast or monstrosity slain by the spell is also cooked to perfection as a result of it. Alternatively, while you are grappling or grappled by another creature, you can use a bonus action to expend 1 charge to overheat the oven's space: the other creature must then make a DC 13 Constitution saving throw. On a failed save, the creature takes 2d8 fire damage and must release you if it can. On a successful save, it takes half as much damage and isn't forced to release you.

"Okay, okay, ha ha, I get it, very funny. Now, not another word about me having a bun in the oven, lest you want to find your own meal."
