The Great Feather Mist Raven is a mystical prosthetic tool resembling a large, intricately designed raven feather with a semi-realistic feudal Japanese aesthetic. The feather is primarily black with subtle iridescent blue and purple hues that shimmer under light, giving it an ethereal quality. The shaft is crafted from dark, polished wood, while the vane features delicate, high-detail textures that mimic real feather barbs, with slight weathering to suggest age and use. The tip of the feather is slightly curved and sharp, hinting at its combat utility.
