The Hextech Dynamo is a medium-sized, intricate device with a steampunk-inspired design, featuring a central glowing blue crystal core encased in a brass and copper framework. The outer shell is adorned with finely engraved hextech patterns and has several rotating gears and pistons that suggest mechanical functionality. The surface is polished with a glossy finish, contrasting the rough, textured edges where the metal shows signs of wear from frequent use. The device emits a soft, pulsating blue light, indicating its magical energy source.
