The Hextech Power Cell is a medium-sized, cylindrical energy source with a glowing blue core encased in a metallic shell. The outer casing features intricate hexagon-patterned engravings, symbolizing its hextech origin, and is made of a polished, reflective metal with a slight blue tint. The core emits a pulsating light, suggesting contained energy, and the entire unit is surrounded by a faint, electric aura. Small vents and grooves are strategically placed around the casing for heat dissipation, adding to its functional yet ornate design.
