Book of Demons

The Archmage BANISHES them.

The Crusader CONQUERS them.

The Great Gold Wyrm DEFIES them.

The Diabolist SUMMONS them.

When the world cracks open and the demons attack, what will YOU do?

The Book of Demons takes an in-depth look at the Abyssal enemies of the 13th Age – the demonic hordes whose eternal struggle to shatter reality causes hellholes, dimensional breaches, and other, even weirder assaults on the world.

For Players:

  • Master the three paths of the demonologist class: the path of corruption, path of flame, and path of slaughter.
  • Discover how to seal a hellhole and save the world

For Game Masters:

  • Six detailed hellholes, and advice on making your own
  • Secrets of the Crusader and the Diabolist
  • Demons! Demons! Demons!

    When will this book be released? Is there a way to sign up for email alerts? I just recently learned about this game and I am in the process of collecting all of the books and will be starting a campaign in my area soon.

    Now that 13th Age Bestiary 2 has been released. Is there any update on a rough estimate of releasing this Book of Demons?

    Really need to find out the secrets of sealing hellholes.

    • Alex Roberts says:

      The Book of Demons is slated for release in late 2017. We understand that the sealing of hellholes is a matter of some urgency.

      • antema says:

        Well, it’s now more than a month later. Has there been progress made on the book, or a more specific release schedule?

        • Cat Tobin says:

          All of the art is now finished, and Rob is just putting the finishing touches to the development. He’s been battling illness recently, which has delayed it. We’re hoping to release it on pre-order at the end of December 2017.

    How many pages is this?

  4. FCM says:

    Errata? In glancing at the text of the pre-order PDF, specifically the sidebar on Page 34 regarding Flare Up and Keep Burning Please, I think it means to say that because the use of Keep Burning changes a successful save to a failure, Flare Up cannot trigger? Flare Up is triggered by a successful save, not a failed one.

    Just noticed something with tiefling demonologists and multiclassing: Since the Charisma->Intelligence swap is a class feature for tiefling demonologists, not a talent, it gets around this from page 106 of 13 True Ways: “The important reminders to keep things sorted out are that a) the key modifier table itself is not affected by any ability score swaps pulled off within class talents, and b) the talents are class elements that are affected by the key ability modifiers.”

    This doesn’t affect much of the more obvious INT-using multiclass combos for wizards, necromancers, and the occultist since the key ability modifier for that side of the multiclass is still INT/CHA. However, any class a tiefling demonologist multiclasses with a talent that lets you swap out the key modifier with Intelligence would let you use just Intelligence for both classes: the bard’s Loremaster, rogue’s Cunning, and commander’s Strategist.

    There are probably some slightly intuitive-ish exceptions/clarifications to force dual-ability-score usage, but I figure it’s good to point this out!

  6. Sam says:

    Ooo, one other thing for me to bring up: Is the Contagion talent meant to apply to spell effects, or *conditions* caused by one of your demonologist spells? While it mentions the word “condition”, every other sentence refers to the spell effects. Does this apply only to actual conditions inflicted by your spells (vulnerable, confused, dazed, etc.), or does it apply to ongoing damage and the like as well?

    This is cool but I sure would like a book that had all the monthly stuff in it instead, including the races that for some reason you removed the playability option for in Bestiary 2. I hate being a negative nancy but the year IS almost over and the stuff put has been…lacking for me. I was a subscriber before when the monthly was around and I liked this game even though getting a group together that doesn’t want to kill the Icons is next to impossible, and I would love more player options to entice people with. Cause that IS what this game is lacking most…options.

    How much content from the full version is in the currently available pre-order preview? And are the method(s) for sealing a hell hole in the pre-order preview?
