The Phantom Dancer is a sleek, ethereal weapon with a flowing, ghostly blade that appears semi-transparent with a vibrant purple and blue energy glow. The hilt is intricately designed with ornate silver filigree, resembling swirling spirits, and the guard extends into sharp, angular points that enhance its menacing appearance. The blade's surface is smooth with a slight iridescent sheen, giving it a mystical and otherworldly quality, while the energy core at the base pulsates with a faint light, indicating its powerful enchantments.
