Shinnok's Amulet is a sinister, ornate piece of jewelry with a dark, mystical aura. It features a large, central gemstone that emits a faint, eerie glow, encased in intricate metalwork resembling skeletal fingers clutching the stone. The amulet's design is asymmetrical, with sharp, angular details and engraved runes that hint at its ancient and malevolent power. The materials appear to be a combination of dark, tarnished metal and a smooth, polished gemstone, giving it a foreboding yet luxurious appearance.
