The Jellyfish Shield is a medium-sized, translucent shield with a semi-circular shape, resembling the bell of a jellyfish. Its surface is smooth and slightly iridescent, with subtle, flowing patterns that mimic the natural movements of jellyfish tentacles. The edges are lined with a delicate, glowing blue bioluminescent rim, enhancing its mystical appearance. The shield's handle is wrapped in dark, weathered leather, providing a stark contrast to its ethereal body.
