Lords of Madness: The Book of Aberrations (3.5)

Unnatural Creatures of Unspeakable Evil
Trembling hands have recorded horrifying stories of encounters with aboleths, beholders, mind flayers, and other aberrations. The victims of these alien creatures are quickly overwhelmed by mind-numbing terror - their only comfort is the hope for a quick death.
This supplement for the D&D game presents a comprehensive look at some of the most bizarre creatures ever to invade the world of fantasy roleplaying. Along with information about the physiology, psychology, society, and schemes of these strange beings, you’ll find spells, feats, tactics, and tools commonly employed by those who hunt them.
Lords of Madness: The Book of Aberrations also provides new rules, prestige classes, monsters, sample encounters, and fully developed NPCs ready to instill fear in any hero.
Product History

Lords of Madness: The Book of Aberrations (2005) is a 3.5 edition sourcebook about everyone's favorite monster type, designed by Richard Baker, James Jacobs, and Steve Winter. This is one case when you can tell a book by the (gorgeous) cover: the demonic mindflayer, tentacles wriggling as it contemplates its cerebellum dinner, perfectly captures the look and feel of this book. It's a gorgeous and eminently useful look at aboleths, beholders, and all of the other aberrations that make adventuring so darn dangerous for fledgling and experienced heroes alike.

The Monstrosities. After a brief chapter exploring "what is an aberration?" and laying out the structure and advice for an aberration-focused campaign, Lords of Madness jumps right into the monsters. One entire chapter is dedicated to each of the major types of aberrations:
  • The Deep Masters: Aboleths
  • The Eye Tyrants: Beholders
  • The Mind Flayers: Illithids
  • The Slave Takers: Neogi 
  • The Eaters: Grell
  • The Wearers of Flesh: Tsochar
Each chapter exhausively examines that monstrous race's anatomy, life, death, monstrous variants, prestige classes, regular classes, feats, unique magic, society, religion, languages, and goals. Each chapter also focuses on an encounter area or sample lair to use in an adventure. Whether that's the neogi wreck of the Mindspider or an illithid sept, beautiful maps and well-designed encounters provide useful adventure hooks.

Wait, the Who? Most longtime D&D fans know the neogi, a slave-taking race of spider-eels originally from Spelljammer. The tsochar are less well known. They are utterly inhuman, shapechanging infiltrators who come from a cold and distant world to our own in order to steal magic. They rarely pass through their world-spanning black gates, and that's a good thing, as they're difficult to detect and utterly revolting to behold. If you're looking for tentacular infiltrators who remind you of crossing a doppelganger with a Lovecraftian elder god, these are a good choice.

New Monsters from the Old World. Want more? The new monster chapter gives us beholderkin, cloakers, elder brains, gas spores, gibbering mouthers, half-farspawn, new illithids, psurlons, pseudonatural creatures, and more. In fact, there are 20 new monsters (or converted old monsters) detailed here. And the art is fantastic throughout.

Fight Back. The "aberration hunter" role is introduced here, with six new prestige classes, new feats, new magic items, and plenty of unique spells. The chapter on aberration hunters also gives the details and descriptions for a number of new secret societies and guilds that band together to fight their mutable, unnatural foes. If your campaign focuses or even leans heavily on aberrations, your players are going to want to read this chapter.

Lords of Madness remains one of the best and most fun books in Wizards' series of prestige monster supplements. The examination of its topic is intelligent and interesting, the monsters and plot hooks are horrifying, and the new rules are well-balanced and make the game more fun. Picking up this book is a no-brainer - especially if you ask an illithid.

We need this item to be Print on Demand. Ebay and Amazon prices are insulting.

Wizards of the Coast is not in the business of providing PoD options on out of print items. These will never become PoD; therefore, you are wasting your time in waiting. You must find and purchase any and all out of print items such as these through Amazon, eBay, and etc. That is just the way it is.

"Wizards of the Coast is not in the business of providing PoD options on out of print items" - uhhh bruh you know there's an entire subsection of this site dedicated to pod options of 'out of print' books from TSR/Wizards, right? I mean, that's objectively a fact. They add new stuff all the time. What we have no assurance of is that they ever read these comments sections. That *might* be a waste of time.

I would like to have a POD option as well. Does anyone know how we can push this forward? Do we just continually ask for it? Or do we have to petition WOD (fat chance in hell) for it.

This is a great book. I play 5e but still use this book as a reference. Hopefully they will make it POD for those that do not own an original copy.

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.
