The Hextech Battery is a medium-sized, cylindrical device with a sleek, metallic blue casing adorned with intricate golden Hextech engravings. Its surface is smooth and slightly reflective, with glowing blue energy lines pulsating through transparent sections, indicating stored power. The top features a circular interface with a bright, central core that emits a soft, luminous glow, surrounded by smaller, symmetrically placed vents for energy dispersion.
