The Frozen Heart is a medium-sized, ornate armor piece with a crystalline blue appearance, resembling ice formations. Its surface is smooth and slightly reflective, with intricate frost patterns etched into the metal, giving it a magical, frozen aesthetic. The center features a glowing blue gem that pulses faintly, symbolizing its chilling power. The edges are sharp and angular, with icicle-like protrusions that enhance its defensive and intimidating look.
