Dark geometric chestplate crafted from deep black iron mixed with obsidian shards. Angular armor panels reflect faint purple highlights and subtle cracks glowing with dim light. The design is rugged with layered square plating and thick shoulder guards shaped like beveled blocks. Chest center slightly recessed with embedded obsidian core. Brown leather straps cross the back with silver fasteners. Edges chipped and weathered, showing faint wear. Realistic PBR metal-stone-leather texture blend, moody cool lighting, Roblox-style chunky structure, detailed depth and surface roughness.
