On the eve of battle the Greenskin shamans invoke the spirit of the great god Gork before the tribe's mighty Waaagh! banner. The banner is liberally daubed with vast quantities of Orc dung, blood and spittle which will serve to absorb the battle-thirst of Gork. The shamans whirl and dance insanely; howling and gabbling in spirit-talk all night long as the Waaagh! banner slowly grows in power. It also acquires a unique odour which is an unmistakable mark of tribal recognition. As the ladz stride beneath Gork's own war banner their hearts swell with pride. When they charge they launch themselves upon the foe with deadly vigour, tearing and rending at their helpless enemy.
