Dragonmaw Shield

A shield is made from wood or metal and is carried in one hand. Wielding a shield increases your Armor Class by 2. You can benefit from only one shield at a time.

With a hinged lower portion, this shield has the appearance of a dragon's roaring mouth, complete with fiery interior. The dragonmaw shield's opening is, in fact, a portal to a pocket dimension. This pocket dimension is a 10-foot cube containing a forge that, due to the insulating properties of pocket dimensions, never cools. It's perfect for getting rid of trash, destroying incriminating evidence, or smelting down looted weapons.

Gnash: When a creature misses you with a melee weapon attack, you can use your reaction to force the creature to make a DC 15 Dexterity saving throw as the shield chomps at their weapon with its fiery maw. On a failed save, the creature takes 1d10 fire damage as the shield breathes a plume of scalding air at them. In addition, if the creature's weapon is nonmagical, then any flammable components, such as those made of wood, are destroyed.
