Horus Heresy: Liber Custodes

The army list for the Legio Custodes is incredibly detailed, with options that really let you build a unique force. I especially appreciate how the Sisters of Silence are integrated, making them feel essential rather than tacked on. This book has already changed how I approach my games.

The background sections on the Sisters of Silence alone justified the purchase for me, and the full army list is laid out clearly enough to build a list without cross-referencing five other books. Only gripe is that a few of the unit entries feel thin on tactics compared to the lore.

The rules section is comprehensive, but the army list feels a bit sparse for the price point. I wish there were more stratagems included to give the Custodes more tactical variety on the table.
