Old-School Essentials Advanced Fantasy: Genre Rules


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!

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.

Advanced Fantasy: Genre Rules

This book contains the rules for playing games in the Advanced Fantasy genre, bringing in material inspired by the beloved 1970s Advanced rules:

  • 9 human classes: acrobat, assassin, barbarian, bard, druid, illusionist, knight, paladin, ranger.
  • 6 demihuman race-classes: drow, duergar, gnome, half-elf, half-orc, svirfneblin.
  • All new classes are carefully designed to match the power levels of the classic Basic/Expert game.
  • Rules for poisons. (Essential for assassin characters!)
  • Advanced options: Optional rules to add extra depth to character creation, combat, and spell casting.
Note that this book is not a complete game! It is a rules module that adds extra player options on top of Old-School Essentials Rules Tome. Spell lists for bard, druid, gnome, illusionist, and ranger characters are found in Old-School Essentials Advanced Fantasy: Druid and Illusionist Spells.


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 available from the Necrotic Gnome publisher website, along with all of the other books in the Old-School Essentials line.

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

So far Advanced Labyrinth Lord has been my go-to to get 1e classes and races in an OSR framework. How does OSE compare?

Researching before I invest :)

General differences between OSE and LL:
- The writing and layout of OSE is focused on usability at the table, making heavy use of bullet points, bolding, subheadings, and so on for ease of quick reference. LL is written in a more traditional style.
- OSE attempts to be as faithful to B/X as possible, while fixing a few areas of obvious contradiction in the rules. LL makes changes to the rules in a few areas (e.g. clerics get a spell at 1st level).
- The physical OSE books are produced as a high quality offset print run with fancy things like ribbon markers and printed endpapers (and a boxed set!), as opposed to the print-on-demand quality of LL.

Differences between OSE Advanced Fantasy and Advanced LL:
- OSE has more classes and races, including acrobats, barbarians, bards, drow, duergar, knights, and svirfneblin.
- OSE includes rules for the new demihumans both as race-classes (in the B/X style) and as separate races (in the AD&D style).

Do the "advanced" race definitions of elves, halflings and dwarves import their AD&D specials? For example, do elves and halflings have a higher chance to surprise opponents?

Nope, the standard demihumans (i.e. elf, dwarf, halfling) have racial abilities based on the abilities of the standard B/X race-classes.

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.
