Diablo: Book of Lorath (Diablo Character Tome, 4)

by Matthew J. Kirby
★★★☆☆

Book of Lorath leans heavily on illustration over lore, landing in an awkward middle ground that even fans have flagged, though the letters between Neyrelle and Lorath are a genuine highlight. Solid but unremarkable, worth it only if you're already invested in these characters

Matthew J. Kirby·February 2026

This is the fourth companion book for the Diablo franchise, set in the time between the end of Diablo 4 and the Vessel of Hatred expansion, focusing specifically on Lorath and Neyrelle. The book itself is heavy on the important artifacts of Sanctuary and their lore. When it comes to actual written content, this has the least of all the companion books, and it leans heavily on illustration, so be aware of that going in. Other readers seem to echo this same complaint, several have pointed out that the book tries to organize an overwhelming amount of relic and gear information, but ends up landing in an awkward middle ground, not quite lore-dense enough for people wanting deep story content, and not quite artwork-focused enough for people who just want the visuals. It's a fair criticism, and one I share.

The written letters between Neyrelle and Lorath are genuinely great, nicely written and feel realistic, and this seems to be the one part of the book that consistently gets praised, other readers have called this exchange one of the most enjoyable parts of the whole thing too. It's also worth noting the book quietly sets up the storyline for Vessel of Hatred before the expansion even released, which in hindsight makes it a nice little preview for anyone who wants to piece together hints ahead of time.

That said, this book is for you if you're invested in these characters from Diablo 4. If you're not, you're not missing much, you can get just as much information about these artifacts from a wiki. And obviously, this book isn't for you at all if you're not interested in the Diablo franchise in the first place, so keep that in mind. Out of the companion books so far, this one feels the most like a solid but unremarkable entry, enjoyable if you're already in deep, but not the one I'd point to as essential.
