A Heavy Arc Rifle is an electromagnetic Arc Weapon devised by the military forces of the Adeptus Mechanicus to slay the daemon machines of the Dark Mechanicum. The Heavy Arc Rifle is powered by ancient Martian electrotech. It sends out shallow parabolas of crackling electromagnetic energy that revolve around each other, forming triple helixes as they blast forth. Should these ground upon a metallic target they will swiftly overload its circuits and banish its animating spirit to the ether.
