Mjolnir is a legendary war hammer with a photorealistic design, featuring a large, block-shaped head made of dark, weathered metal with intricate Norse runes engraved along its surface. The handle is wrapped in aged leather, providing a firm grip, and the hammer's proportions are exaggerated to emphasize its mythical power, with the head being disproportionately large compared to the handle. The metal has a slightly reflective, hammered finish with visible scratches and dents from countless battles, and the runes glow faintly with a mystical blue light when wielded.
