Ulraunt's Guide to the Planes: Acheron

Quill & Cauldron presents to you a very special 300+ page tome, aimed at both players and dungeon masters.

It is narrated by none other than Ulraunt, the Keeper of Tomes at Candlekeep, and also supports epic level play (as introduced in Epic Characters).

Below is a short description of what you will find within each part of the book.


  • A narrative told from the perspective of Ulraunt, designed to inspire and create story hooks, as he descends through Acheron's four layers with his band of misfits.
  • Details on Acheron and each of its four layers, including environmentsfauna, and flora, how to get there, what hazards to avoid, and much more.
  • A detailed look at each cube face of many of the cubes that exist on the various layers, such as Nishrek, home of the orc pantheon, and Clangor, home of the goblinoid pantheon.
  • Tables to help you quickly create your own cubes.


  • We explore a total of 16 deities, including Bane, Laduguer, Deep Duerra, Urdlen, and the entire goblinoid and orc pantheons.
  • Each deity includes nifty tips for roleplaying them, mighty stat blocks, awe-inspiring lairs, and templates for creating versatile avatars.


  • One new playable race and one new subrace.
  • Eighteen new and unique subclasses, such as the exploration-focused surveyor artificer, the sinister blood hunter of the order of the warmonger, or the malleable druid of the circle of warshaping.  
  • Over 50 new spells of all levels, each inspired by the prevalent themes of Acheron such as atrophy, cold, magnetism, metals, psionics, and storm.


  • 138 new stat blocks, some based on existing lore, others seen here for the first time.
  • Four war mounts.
  • Three new war machines.
  • Seven unique characters from the Forgotten Realms, such as the fabled Obould Many-Arrows.

  • Print
    • The book is available in both hardcover and paperback.
    • The paperback is available in both standard and premium colors.
    • The hardcover is only available in premium colors for a truly premium experience.
  • PDF
    • The PDF is available as single pages and as spreads.
    • Both versions are hyperlinked throughout the table of contents and the appendices.
    • The page number is clickable on every page, allowing you to instantly return to the table of contents.
  • With the recent global pandemic affecting several lives and taxing medical resources, it is important that we each do our part.
  • We wish to help an organization that has worked against the spread of misinformation and consistently provided care around the globe.
  • For that reason, a portion of every sale will go to Doctors Without Borders.

How's the updating and corrections of this product going?

I'm interested in getting a physical copy, but I abstained to get it when it came out because it was inevitable that there might be some mistakes (as it's normal in products of such a scale).

There are some issues with the statblock for Yrrga on page 280:

- Its "Indoctrinate" ability mentions targeting creatures it can sense with its "Sense Nihilism" trait, but it has no such trait.
- It simultaneously has immunity and vulnerability to Pyschic damage
- Its ability "Mind Shatter" incorrectly calls itself "Aura of Madness" when describing a creature becoming immune to its effects at the end

I don't know if this is the right place to post this but I wanted to point out a few typos:

Page 146 in the Steel Warden Magic table, it says Spell Level but in the table it shows the Ranger Level instead.

Page 142 under the Ferrous Adept feature, when it says "the oxidization cantrip", the word cantrip is italicised.

Steel Warden is a ranger subclass, so I don't think it's a typo.

Feodor R September 12, 2020 3:13 pm UTC
It is a typo. The table says Spell Level as one of the headers but below it it doesn't show the Spell Level, it shows the Ranger Level in which you get them.

I love the book and I have a quick question about the avatars. Can we use any stat block we want or only the categories of creatures listed under each god
Customer avatar
Callum R June 14, 2020 10:44 am UTC
Not sure if this has been asked before, but what was the reasoning behind the decision to make some of the gods statted in the book not 30th level spellcasters? Iirc it was just Baghtru and Khurgorbaeyag.
Customer avatar
Marc A July 27, 2020 4:58 am UTC
Hi Callum,

Good question!
For Bahgtru, it was simply that he doesn't really concern himself with magic. He's not the cleverest of the bunch and he just likes to smash things.
For Khurgorbaeyag, we went with the Booyahg route laid out for goblin magic. We think it makes sense that their culture and beliefs are reflected in their patron deity.

So, I had more to my previous comment. However, I accidentally hit add comment before I finished, and I couldn’t get my edit in time, and the limit timed out. So here’s my second part of the review. I won’t rewrite everything, as it was a lot. However, I’ll write out the gist of it.

I loved the Character Options. The races seem fine. Didn’t really glance at them too much, but they seem fine. I loved the Artificer class, and seeing as it’s so new, it’s nice to have even more options. It was also nice to see the Blood Hunter get more love. I love the class. It was also nice to see a melee sorcerer. Warlock and wizard both got official melee subclasses, so I found it strange that the sorcerer didn’t. I also noticed that my feedback on the daggerspell wizard was taken into account, so that’s nice to see.

As for the bestiary. I remember testing some of these monsters, and it was nice to see them, especially the Hundred-Handed Ones. Though, I love CR 30+ monsters, so the...See more

Alright. I had a review written out, but it got deleted. So here’s my second go round.

I have finally read through the book. Not cover to cover. I don’t have the patience for that. However, I did read a good portion of it. The narrative, the deities, the characters options, things like that. If you want my general review. I love the book. Epic Characters got me interested. The one “complaint” I have is that just as I finished entering all of the Epic Classes into my Fight Club 5, you released the update. So now I have to go back and revise everything. But that’s not a real complaint against the book, just something that annoyed me. I was a little hesitant to buy the Shadowfell book, seeing as I didn’t want to spend $25 on a book that was subpar. However, I was thoroughly impressed when I did XXX the bullet (or I guess, XXX the spear), and even made Vecna the final villain of my campaign as I’ve said before. The quality of that book insured that I would, at the very least, buy the next...See more

What are the odds of getting an extended look at Sigil and the Outlands? They could probably be combined into one book, though honestly you could make so much content on either alone. I'd love to see them updated and expanded for 5e!
Customer avatar
Marc A April 24, 2020 6:02 pm UTC
Hi Alex,

Unfortunately, the Planescape setting isn't part of the community content agreement.
That said, we'd absolutely love to explore Sigil and the Outlands if it ever becomes possible for us to do so.

Sorry if this is a repost, as my thing kinda freaked out. Out of curiosity, do you guys plan to do the other Outer Planes, or are you guys sniping things as they interest you? I'm cool either way, as it's nice to see Acheron get some love, as it's normally pretty heavily overlooked. It'd be cool to see some other planes get this treatment that are less known as well, like Carceri, the Beastlands, Arcadia, Pandemonium, and etc. Another fun one could be the Quasi and Para Elemental Planes, as they tend to get even less love, though some of them would probably be hard to make a real book about, like Vacuum. Whatever you guys do, I've been loving the Ulraunt series so far, keep up the good work!
Customer avatar
Marc A April 21, 2020 3:32 pm UTC
Hi Jonathan,

Thank you for your kind words.
We agree entirely. Many of the planes could use with a lot more attention.
There are so many interesting locations beyond the Material Plane but it's spread across multiple sources across multiple editions of D&D.
We want to make those places accessible for 5e players. Hopefully, that's what the Ulraunt series does.

And yes, so long as there's a demand for them in the community, we want to keep making them.
Ideally, we'd love to get to every plane eventually.

We have a few other planes in the pipeline and at least a few of them are Outer Planes.
It's partly what we want to do and partly what we think needs to be brought into 5e.
After Shadowfell the obvious next plane would have been the Feywild.
However, each book takes us 1-1½ years to make from start to finish and sometimes we just need a change of pace. Something very, very different.
It's still too early to tell where we'll...See more

As someone playtesting, I for one certainly look forward to some of the future installments. I'm personally looking forward to your first foray into the upper planes. Things like the Shadowfell and Archeron are sometimes hard sells for parties. Little do they know that Mount Celestia or the Beastlands will be just as deadly...
Customer avatar
Liz M April 21, 2020 11:14 pm UTC
I look forward to the next installment as well. A foray into the upper planes is something that never crossed my mind, but I suppose they can also present fearsome foes of their own. Despite this, any plane could prove to be a hidden gem, whether it be a realm as big as Hades, or the simplistic confines of the many elemental planes. Every world has something unique to add to the mix. It just takes a little ingenuity on the DM’s part
Customer avatar
Jonathan F April 22, 2020 8:19 pm UTC
While they could be hard to expand on, The Quasi and Para elemental planes are also pretty cool places as well with some right world building. For example you have the Plane of Ooze situated between Earth and Water, where you could build and entire network of wooden bridges and villages over an endless murky swamp that is literally bottomless, with ancient prisons being locked untold miles beneath the surface. Or the Plane of Dust, when is modeled after the concept of disintegration and erosion, situated between the Plane of Earth and the Negative Energy Plane, where you can have an adventure in an ancient and forgotten city sliding across the sands of the plane toward its eventual and final destruction at the border of the Negative Energy Plane, slowly disintegrating the whole time. etc etc etc. As it stands though, I"m super happy with both the Shadowfell and the Acheron books as both places are very under explored even in old content, and I'm sure I'll love whatever comes next.

Heya, I’m a little bit confused about how Tanarukks are treated in Acheron. Page 36 says that they’re among those trained in the Barracks by Ilneval, but page 73 says that they’re blasphemous creatures that are barred from Nishrek in the afterlife.
Customer avatar
Marc A April 06, 2020 6:48 pm UTC
Hi again, Callum,

Tanarukks were originally intended to be treated like other orcs. The further we delved into the lore, however, the more it became clear that it just didn't fit.
So, naturally, we made revisions to make it cohesive but the mention on page 36 must have slipped past our radar.

Nice catch though and thanks for bringing it to our attention!
I'll be adding it to our errata.

What needs to happen before we can the Shadowfell as a Print on Demand book? Because I'd really like to have it in a hard copy as well.
Customer avatar
Marc A April 16, 2020 10:10 am UTC
Thanks for chiming in, Jonathon!

Shadowfell isn't eligible for PoD with the current rules and there's no set way to change that.
With some luck, the powers that be can be convinced to make an exception for Shadowfell if enough people express interest in it and Acheron sells well enough.
That's pure speculation though. Still, I think it's the only chance we've got.

Ah, I remember testing some of the things for this. Shame my group was so homebrewed that I couldn't get any meaningful data out of it! :P
I look forward to buying this next month. Skimming through the preview, it looks very fun.

Do you know how the POD handles different countries like the UK? I prefer physical books but have my concerns about surprise import fees... assuming the customs is even working right now. xD

Yea, for playtesting we really need a comparative baseline across the board.
But Hiten is the expert here :)

Regarding print copies, I believe European copies are printed in the UK and sent from there.

I'm really sorry I forgot to add your name to the list of folks receiving complementary .pdf copies! We had so many playtesters and for some reason your name slipped through the crack. You were extremely thorough in the feedback you did provide, so you absolutely deserve one.

We'll get rectify this ASAP! Email coming soon. Thank god you posted.

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
