500+ Combat and Social Weaknesses. This book provides combat weaknesses for every monster in the Monsters of the Multiverse and social weaknesses for every monster that speaks a language available to player characters. The inspiration for these weaknesses comes from a creature’s anatomy, description in the Monster of the Multiverse, or well-known legends. Each weakness presented in this book is meant to be a trait that can be appended to a creature’s stat block.

14 Custom Illustrated Experts. This book contains characters knowledgeable in each of the different monster types to walk you through these monster weaknesses. These characters can be used in a campaign as NPCs or potentially be the authors of tomes or notes found in a library. 

Advice and Mechanics. This book contains advice and mechanics for discovering monster weaknesses as well as designing your own!

Testimonials for Monster Weaknesses (for the Monster Manual):

  • 5-Star Review: "In my humble opinion, this is the single best resource on the DM's Guild." - Emerson C.
  • 5-Star Review: "These are some of the coolest, unique ways to spice encounters up. Rewards players thinking outside of the box and introduces more mechanics like researching monsters (in-game of course) for your party. Definitely worth picking up." - Zack S.
  • 5-Star Review: "This is an innovative, comprehensive, and polished book from a talented team. Surface level, the book looks amazing. Fantastic art and an organized layout parallel what you'd expect from an official D&D 5e book. Digging into the actual content reveals a treasure trove of ideas for DMs add to their games. The addition of concrete social weaknesses with mechanics to monsters is genius. We've all either had players or been the player who loves to circumvent the DMs prepared combat in favor of a social challenge instead. Also, the new combat mechanics are simple yet creative, and are a nice incentive for characters who like to research a monster beforehand. Finally, the extra touches in Monster Weaknesses make the book fun to read, like the NPC experts introducing each classification of monster. This is an excellent purchase." - Jose G.

Would you ever consider doing a Monster Weaknesses supplement for the entries from Volo's Guide or Mordenkaiden's Tome that didn't make it to Monsters of the Multiverse? Like the various Orc chosen (Blade of Ilneval, Claw of Luthic, etc), for example.

Hey Parrallathan,
We don't currently have a plan to do that - our next weaknesses project will be Spelljammer monsters. However, if there is a particular monster that didn't make it into MotM from VGtM or MToF that you'd like some weakness suggestions for, feel free to ask here, or tag me on Twitter @frictionlessDan and I'd be happy to help brainstorm.

Thanks for offering to help!

The list of removed monsters from the legacy content in MotM is pretty slim - the ones I'd want weaknesses for most would probably be the orc varieties (Orc Blade of Ilneval, Orc Claw of Luthic, Orc Hand of Yurtrus, Orc Nurtured One of Yurtrus, Orc Red Fang of Shargaas), the two Illithid sidebar entries (Illithilich, Mind Flayer Psion) and the Yuanti Malison Types 4 & 5.

I can live without weaknesses for Cows, Rothés, Xvart Speakers and Abyssal Wretches. :P

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.
