Underworld Lairs for 5th Edition

Watermarked PDF

Darkness & Death in the Underworld

  • An encampment of the nearly extinct drow defending an Underworld entrance.
  • A cathedral lit by the eerie green glow of thousands of candles.
  • A powerful lich inhabiting the corpse of a giant petrified worm.

Inside, you’ll find these and more! The standalone, single-map adventures for characters of levels 3 to 15 will challenge players with the strange societies of the derro and darakhul, fantastical locations such as the Skullcap Forest and an outpost of the Ghoul Imperium, and powerful opposition including a clan of cave giants called the Sunseekers.

Use these as a stop along your campaign or in a single, standalone session. Whether a party of heroes or those of… flexible moral fiber, they will enjoy the struggle and triumph of these Underworld Lairs. That is, unless the cave dragon adds them to the foundation of his ziggurat of bones!

Underworld Lairs uses standard monsters as well as surprising new creatures from the Creature Codex and the Tome of BeastsBoth monster books are required for maximum utility.

A question about the stat block for the ferrovore (p. 7): The text for the "antennae" attack says, "Hit: The target’s Constitution score is reduced by 1, and the ferrovore attached to it." This seems to be an incomplete sentence. What is supposed to happen to the ferrovore on a hit?

Thanks for posting, but the ferrovore is not a monster that appears in this book. We thoroughly reviewed the text in this title and could not find the entry or an antennae; page 7 is a full-page map.

We are always happy to correct any error people find, but in this case, is it possible you are looking at a different PDF?

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.
