Champions of Death gives players the opportunity to play as undead characters, such as vampires, ghouls, wraiths, and wights. Characters can play as servants of Nagash in his war against Sigmar or take on the role of unexpected allies of the Forces of Order — though those foolish enough to spurn the Undying King may face a fate far worse than undeath.

Champions of Death presents dozens of new Archetypes, including those for the Soulblight Vampires, Ossiarch Bonereapers, Nighthaunts, and Flesh-eater Courts. The book also includes new Species, factions and subfactions, new Talents, Miraclesof Nagash, and dozens of new spells. As well as that, Champions of Death provides GMs with advice and guidance on running Death-focused campaigns and how to handle undead characters that have allied with the forces of Order.
