Wildly unpredictable, savage, untamed and violent, Waaagh! magic cannot be controlled by anything with even a shred of sanity. The Weirdnob Shamans are the masters of this type of magic. Never truly in control of their own bodies, they twist and twitch and gibber as Waaagh! energy courses through them, staring at sights only can they see and talking things that are not there. The larger the gathering of Ironjawz around one of these strange orruks, the bigger the blast of Waaagh! energy will hammer into the enemy like a particularly smelly gust, or maybe a massive green foot the size of a mountain will kick the entire enemy army in the face.
