Hajime creates ores for his arm

The arm was fitted with all sorts of interesting gimmicks. Some of them had originally been part of the arm when he’d found it in Oscar’s workshop, while others were new additions of Hajime’s own design. He had used his creation magic to materialize all kinds of specialized ores and added them to his arm. As it was now, his artificial limb was an artifact that rivaled the greatest national treasure of any kingdom.
