As two actions, choose a manufactured metal object, such as a metal weapon or a suit of heavy or medium metal armor, that you can touch or see within 10 meters. You cause the object to glow red-hot, searing any creature in physical contact with the object. The creature must make a Fortitude saving throw.

On a failure, it takes 5d6 fire damage and must drop the object if it can. If it doesn’t drop the object, it has disadvantage on skill checks until it drops the object.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

If a creature is holding or wearing the object at the start of its turn or picks it up, it must repeat the saving throw.

Augment

You can increase the damage by 3d6 for each additional mana expended.
