A charging Necrolith Colossus is nigh impossible to stop, its huge arms raining blow upon blow down on the foe, each sending dead and broken bodies flying in all directions.
During the Combat phase of any turn in which this model charged, every attack it makes that causes an unsaved wound allows it to immediately make one additional attack. These additional attacks also benefit from this special rule.
Note that any unsaved wounds caused by the Stomp Attacks (D3) special rule do not benefit from this special rule.
