Create a stylized fantasy berserker armor made of cracked bone plates and dark obsidian shards with torn fur, frayed red cloth wraps, minimal bronze trims, jagged chunky shapes, and glowing magenta sakura-rune cracks following a 60% dark bone/obsidian, 30% red cloth, 10% magenta glow color balance, inspired by feral Oni demons in a painterly non-realistic style.
