This is a fantastic resource! It has everything I could ask for in a sourcebook on Acheron. I really hope the author continues this series, its been incredibly helpful.

I bought this book some time ago, and have completely forgottten to wrtie a review. It is excellent in detailing not only Acheron, but also monsters and deities that inhabit. This book made the plane much more dynamic and interesting than the short section given in the DMG, and I am not even mentioning the amazing artwork found inside. To any potential readers wondering if the hardback version is worth the extra price tage, I can say the cover and binding are excellent, and show no signs of deterioration thus far.

Let me just say I bought this book based on the excellent quality of their other products and my overall interest in the planes. The book did not fail to meet my expectations.

Most notably, this book is a tome on the plane of Acheron. It's a big book, but it's also just stuffed with useful information (unlike many books out there, particularly WoTC and Paizo). The descriptive story telling (much like what is found in their book on the plane of Shadows) succeeds in providing the feel of being in Acheron. The beastiary secion is huge but it doesn't overshadow the detailed descripions of each area in the plane. The planes mechanincs are presented nicely and includes variations to the rules where appropriate. This book is a "must have" if, like me, you collect books regarding the planes.

As for the book itself, it's well written and well organized. The quality of printing is very good and clear. The paper could be nicer but it does the job. The book was nicely packaged for shipping and arrived undamaged. Overall, a quality product in every way.

I have shadowfell, but just got acheron. I absolutely love it, and plan to run an acheron campaign. I'd recommend the domination domain cleric especially.

To me this books is exactly the reason that got me into DnD in the first place. It is a tome that not only gives statblocks and player options, but gives extremly detailed and well written lore that inspires me as a DM to try and incoperate it into my games. Along with the Shadowfell guide I say this a must buy for DM looking for more extraplanar information and really want to challange their players. This book is well worth it and I can't wait for more guides like it to come out.

An excellent resource, well detailed, with a lot of good locations, challenges, and a very extensive menagerie of new beasts. i would love a treamnt like this for more of the outer planes, tho i fret at how feasible that would be.there is deep push woven through the work extolling thier supplement about epic tier of play (21-30), but they take pains to point out it is optional. I also appreciate their asking for feedback, but the surveys themeselves are rather extensive.

If you've worn out your welcome in the Hells, come se how the somewhat more lawful side lives.

Reccomended

Overall, a great purchase. Although my group doesn't usually enjoy the challenging and horror side of DnD, I will probably keep this around for inspiration. This installment in UgttP is styled a bit differently from its companion, as it forcuses more on the deity stat blocks than lore bits, though most plot points of these are said in other WotC books. I especially enjoyed the bestiary at the end, as my PCs has just gotten to Lvl 10, and running out of high CR Orcs to slay on the Material Plane. Some of the monsters contained therein are a bit too powerful, as just a single Caedes can rival the power of Hruggek. And it states that "They are quite numerous" within the PDF. The spells were great to style the Cubes that I was creating, and a few had some incredibly fun moments. The Character classes were all solid additions, except for a few clunkers, (Looking at you, Domination Domain and Oath of Fulmination) I also thought the Eternal Blade was a bit similar to the Bladesinger, though I think I'll consider them a special kind of Bladesinger in Elven Society for differentiation. The Mythic Options were a big treat in case my PCs have enough determination to get to Lvl 30, with the exception of mass-command. I just thought it was underwhelming, with such little range. If it had a large increase in range, I think it would be much more deserving of the 1st level mythic spell slot. The Story was a nice touch, though it strayed a bit at times. Ill use it for an example of Roleplaying the events happening on Acheron. All in all, the PDF is certainly impressive, as the authors creatively produced Monsters, Subclasses, Deities, and Spells that can be used in almost any situation on the plane. And although some issues remain, I believe that the authors can fix them in due time, as the PDF doesn't rely on one good element, but sheer versitility of the entire product. Well done.

This book was GREAT. All the gods are fantastic and detailed in every way needed to rp them and this book has some of my favorite classes of all time.

Between the story telling elements, all new mechanics, and interesting lore I had a hard time deciding what was my favorite part of this book and I thought it would be cheating to say everything. Not a second you spend reading will be wasted. Almost every time I read something new not only did my knowledge of Acheron grow (you'd hope that would happen with a book like this) new ideas that had nothing to do with Acheron to drop into my setting. There is something in this book for everyone.

WotC if youre listening, canonize this book. Make all the new lore offficial because frankly, its higher quality than a lot of what has been put out in the stores .

There is not a lot to say that hasnt already been said in other reviews but I must say that when i got my copy in the mail I thought, "wow this is heavy."

I figured there was a ton of filler but there just wasn't. It is jam packed with lore and of all places now I want to run a campaign in Acheron! There are enough monsters in this book to be a full fledged new compendium of its own and they are really well statted. I recognize familiar creatures from decades of lore and I don't think a single Acheron creature from any edition has been skipoed

If this series is the closest we get to a Planescape update I'm kind of fine with that.

On a side note, and possibly my only complaint is that in the softcover print copy I am 99% sure there is a whole lot of art that didn't make it into print. There are a lot of blank spaces in the last pages that look like there is supposed to be art

This book is phenomenal! It's full of absolutely riveting lore, kickass subclasses, challenging opponents and an incredible swing at conceptualizing an Outer Plane (all of which are designed to be, to quote a very wise man, "inconcievable")! Every page of this book has new and awesome info that I'm more than ecstatic about throwing at my players to spice up our games! After all, who doesn't want to take on epic levels and go toe-to-toe with dieties of war on their home turf? Seriously Q&C, 100/100, 1,000/1,000, Natrual 20, whatever y'all wanna take. This deserves to get to the top of the charts for sure and I absolutely can't wait to see where Ulraunt and his wacky tag-alongs take us next!

I love it. The details of the characters and the new spells was the first thing I looked at. After a day reading: What I appriciate most is the amount of data and idea's that I get from the book, combined with my own twisted way of thinking, I know it will improve my GM skills.

As a fan of Planescape and other lost campaign settings I am a sucker for things like this. That being said I will never regret buying this tome in harback. I love it. Good work guys. Seeing that someone else stated the hecatoncheires sucks, but looking at it I know you did a far better job than I. Also I am a HUGE fan of having level 21+ content for those who need it. 5 Stars guys :) Oh and in closing, it pains me to see the Arcane turned into a Mercane ... but the picture is fantastic.

You know, I was having a really bad day until I saw this released. It was an instant purchase for me. I am astounded by the depth that went in to this. It feels like a fully fleshed out guide to the entire plane and I can't imagine the amount of research that went into this. The encompassing story behind it too is wonderful. I feel like I just bought an official WotC product. This is on par with Explorer's Guide to Wildemount in its design and construction to me. Bravo everyone who worked on this. I am so stoked for what you have next to show us. Arborea and Corellon? The Feywild? Limbo? Mechanus? The Elemental Planes? Each one would be a gift.
