Army building in Legions Imperialis just got easier with Liber Strategia—a massive 240-page tome that brings together and updates content from the core rulebooks, The Great Slaughter, The Devastation of Tallarn, and The Rise of the Dark Mechanicum.
Inside you’ll find fully updated Detachments and Formations for every major faction, including the Legiones Astartes, Solar Auxilia, Mechanicum Taghmata, Dark Mechanicum, Collegia Titanica, and Knight Households—the latter now replacing the outdated Strategic Asset rules from the main rulebook. It’s the single most comprehensive reference yet, making it an essential resource for every Legions Imperialis commander.
