D&D Denizens: Underdark Monsters


With so many monsters having been created for previous editions of the game, only a portion could be included in the new fifth edition Monster Manual. This document updates several of those older monsters absent from the new edition, specifically ones tied in some way to the theme of madness or ones that might be found in the Underdark.

  • Allip (CR 3)
  • Crypt Thing (CR 2)
  • Ophidian (CR 1)
  • Phantom Fungus (CR 1)
  • Shocker Lizard (CR 1/2)
  • Thoqqua (CR 2)

Hi Scott. I just spent some time converting this for use in FantasyGrounds for an upcoming Out of the Abyss game.
Since I've already put in the time, I'd be happy to send the exported file to you for distribution with your PDF to save time for other FantasyGround DMs.

For the ophidian, if Dex is reduced but not to zero, would you say one of the mentioned spells is required to return the Dex loss, or is that only if they reduce to 0?

Sorry - haven't logged in on this account for a while! I would say the spells are needed only if reduced to 0. Otherwise, the stat should return to normal after a long rest. I'll amend when I get a chance. Good eye!

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.
