Battletome: Orruk Warclans is 128 pages of might makes right, with a hefty background section covering these belligerents, as well as rules split between the brutal Ironjawz and the cunning Kruleboys. Both halves of da Waaagh! get their own Battle Traits, Battle Formations, Heroic Traits, Artefacts of Power, Spell Lores, and Manifestation Lores, while the Ironjawz also get a Prayer Lore. There are a total of 16 warscrolls for the Ironjawz and 17 for the Kruleboyz, as well as a brand new Spearhead – the Ironjawz Big Mob.
If you want to combine sheer force and circuitous scheming then the Big Waaagh! Army of Renown gives you a chance to bring both halves together, while each side also gets its own bespoke Army of Renown and Regiment of Renown. On top of that, you can build your own ferocious hero with a new Anvil of Apotheosis, and conquer the lands with additional Path to Glory rules.
