Opening Vibe / First Impressions

I’m really thrilled and excited that someone made a Game Master book almost right out of the gate so to speak. For those who might not know, Deux is the term for GM in Gates of Krystalia. It’s also a term to describe the gods of the in-game world as well. This will come into play further on in the book.

What Makes Last Deux Stand Out?

Every good TTRPG needs a solid Game Master section, a whole book being preferable. Last Deux delivers in spades along with great art, monster creation guidelines, and lots of setting lore. Gates of Krystalia is a very rich setting that covers a lot of subgenres in anime/manga. As a bonus, they included solo rules in this tome as well.

Features That Hit Me Right Away:

There are a lot of really nice sections of Last Deux. I think the two that jump out the most are the various worlds because they had me at “Mecha.” The other thing I really liked is the basic how-to-run-the-game section in the first chapter. The setting is rich and the whole book is perfect for TTJRPG Game Masters just starting out. Also, did I mention Mecha?

Who This Supplement Is For:

Obviously, this one is aimed at players in the Deux role for Gates of Krystalia Honestly, I’d recommend this for fantasy GMs, TTRPG GMs, and anyone new to Game Mastering regardless of the system. GMs with a strong anime/manga background would really benefit from this book. Also, someone coming from RIFTS would benefit from giving this book a look.

Closing Thoughts:

I really love this supplement. Much like the rest of GoK, even if I don’t use it for the game it’s written for. Great advice. Lots of good setting construction. I’ll have more on this book at a later date. Please give Gates of Krystalia: Last Deux a look if you get a chance. My DTRPG Affiliate Link for this book.

I say it every year, but I think 2026 bears repeating it. This year I intend to write more, read more, and discuss cool TTRPGs as well as supplements. Most of all, let’s just have more fun. Let’s explore. Let’s save the kingdom from the evil warlord. Let’s discuss all the fun stuff in gaming that we love.

With the world in the state it finds itself in today, please be kind. Please be considerate to one another even if we don’t agree. Lastly, please pursue the thing that brings you the most joy without harm to others. Thank you!
