A new edition launch box wouldn’t be complete without a mighty tome full of rules, background lore, and spectacular art. The 360-page hardback Warhammer Age of Sigmar Core Book is a thing of beauty. It includes all of the information you need to get started in the new edition of Warhammer Age of Sigmar, complete with a monstrous background section that brings you right up to speed with all the latest developments in the aftermath of the Broken Realms saga.

The Core Book also includes rules for fighting open play battles, and a section dedicated to the detailed Path to Glory system that lets you grow your forces across progressive narrative campaigns. For competitive play, there’s a matched play Battlepack comprising a set of balanced battleplans.
