The Orruk Warclans love to fight – in fact, it’s no lie to say that their entire culture revolves around conflict. The swamp-dwelling Kruleboyz are an unusual breed of orruk, for they prize deviousness over brute strength. To the Kruleboyz, winning by underhanded means is worth more than claiming victory in a straight fight – and they're very underhanded indeed...

Ardboy Big Bosses are veteran Ironjawz with an eye for the battlefield and enough bellowing presence to browbeat their lads into line. Only the toughest of Ardboys survive long enough to become a Big Boss – these formidable warriors can turn a boisterous orruk horde into a disciplined killing machine that advances in a semblance of formation before crashing into the enemy like an armoured fist.

Zoggrok Anvilsmasha is a legend amongst the Ironjawz, for he has mastered the art of hammering the destructive force of the Waaagh! into iron, stone, and bone. Accompanied by Klonk, his rockbrow squig, Zoggrok uses his 'bashin' tools' to channel Gorkamorka's power into the weapons of orruks gathered around him. These green-hot blades thrum with wrath, eager to unleash their raging energy in combat.

To be a Tuskboss, an orruk must claim mastery over a particularly ferocious Maw-grunta – an utterly monstrous hog, with enough brute strength and dim-witted determination to batter through anything in its path. These mounted warlords lead the charge by steering their stampeding behemoths straight into the enemy lines, striking down foes left and right as the beast barrels forward with explosive impact.

Brute Ragerz hurl themselves at the biggest and meanest foes, swinging huge two-handed weapons with brutal force. They're driven by frenzied arrogance, desperate to overcome the humiliation of a previous defeat – few things are more dangerous than an orruk determined to prove just how ’ard they really are.

Roll your way to victory under the light of the Bad Moon with this awesome dice set for Warhammer Age of Sigmar.
