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 sides. The handle is wrapped in aged leather, providing a secure grip, and the hammer's proportions are exaggerated to emphasize its mythical power, with the head being disproportionately large compared to the handle. The surface shows signs of battle, including scratches and dents, while the runes occasionally glow with a faint blue light, hinting at its divine origin.
