An Inferno Chakram's design consists of a black outer wheel with four large spikes along the edge. The handle in the center is a black cross. The design in the middle consists of four red, vaguely teardrop-shaped loops of metal that connect to the handle by the tips and to the spikes on the outer edge by the wide end.
"Inferno" is a Latin name for the Christian Hell, and has come to be a synonym for an intense, raging fire.
The ground combo is very simple, starting out with a simple slash to the left. It ends by throwing the Chakrams while spinning.
The aerial combo is even simpler. It is simply throwing the Chakrams straight to the ground.
