Monsternomicon: Mind Flayers


Potent psionic blasts. Writhing face tentacles. Purple-ish skin, slimy and cool to the touch. Extracted brains. All these things and more help define the term “mind flayer” – but what more are these aberrant creatures? What drives them? Find out within.

This monster supplement provides 5 new creatures:

  • Alhoon - a mind flayer lich
  • Brain Golem - a stalwart ally made entirely of discarded brains
  • Elder Brain - the center of a mind flayer community
  • Ulitharid - a rare and highly advanced mind flayer
  • Mind Flayer Vampire - ravenous and bestial, it requires brains and blood to survive

Additionally you will find adventure seeds and a sample sept (lair) map, along with suggested random encounters.

I have other DM's Guild offerings, as well:

I think there's a typo on page 8. The Elder Brain's Tentacle Thrash attack seems really weak, and the wording suggests there's a number missing. "9 (1d8+4) bludgeoning and damage"--is there supposed to be a psychic damage rider?

Please post your reviews and feedback - I will issue minor updates as needed.

Furthermore, I have a substantial update that I will push to this article with 4 more illithid-related creatures and expanded community/ cultural information ** for free ** once it hits the "Copper Seller" status!

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.
