The Grazer Heart is a vital component harvested from the robotic Grazer creatures, resembling a high-tech organic heart with a blend of mechanical and biological elements. It features a central core encased in a translucent, slightly glowing membrane, surrounded by intricate metallic veins and synthetic muscle fibers. The surface is smooth yet detailed, with a pulsating light effect that suggests its energy-rich nature, colored in deep blues and purples with hints of orange where energy concentrates.
