You call forth a wave of molten heat that breaks down objects in its path. Choose one non-magical object within range that is no larger than a 3-foot cube. If it is small enough and would be melted by intense heat, such as a weapon, a lock, a shield, or piece of armor, this spell melts it to the point that it cannot be used for its original purpose. Otherwise, the object takes 10d6 fire damage.   If the object is being held or worn by a creature, the creature must make a Dexterity saving throw. On a success, the target item isn't melted nor does it take any fire damage. On a failure, the creature holding the object takes 6d6 fire damage.
