Old-School Essentials Classic Fantasy: Monsters


Old-School Essentials is an adventure role-playing game of exploration, danger, monsters, and magic. The game is intentionally rules-light, putting the focus of play on imagination, improvisation, and fun. The rules are optimised for ease of use at the table, with meticulous attention to wording and layout clarity. What's more, Old-School Essentials is 100% compatible with the classic Basic/Expert game from 1981, meaning that decades of adventure are at your fingertips!

Classic Fantasy: Monsters

Old-School Essentials is a modular game where the core rules of the game are extended by additional "rules modules" which add content for different genres of fantastic adventure. This book contains a classic selection of monsters suitable for Classic Fantasy campaigns:

  • Over 200 fearsome monsters to challenge characters of all levels.
  • Complete encounter tables for dungeon levels 1–8+ and all types of wilderness terrain.
  • Procedures for generating parties of NPC adventurers and stronghold patrols.
Note that this book is not a complete game! It is a rules module that adds referee-facing content on top of the Old-School Essentials Core Rules.


The content in this book is 100% compatible with the classic Basic/Expert rules (B/X) and can thus be used with any B/X-based game.

Deluxe Print Edition

A deluxe, sewn-binding hardcover edition of this book is currently being produced and will be available for sale at the Necrotic Gnome publisher website from November, along with all of the other books in the Old-School Essentials line. A deluxe boxed set of the core rules plus all of the Classic Fantasy rules modules is also being produced!

Note that there is no print-on-demand edition of this book!

All-in-One Rules Tome

For those who want a complete game in one book, the Classic Fantasy Rules Tome compiles the Old-School Essentials core rules with all of the Classic Fantasy content, forming a complete game in a single, 296-page tome. For those who like modular books, this content is also available in the form of a bundle of 5 PDFs, the Classic Fantasy Black Box.

Product Information
File Size:
10.86 MB
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.
