Advanced Dungeons & Dragons (AD&D 1st Edition)
Advanced Dungeons & Dragons (AD&D) was released between 1977 and 1988 as a reorganized, expanded, and more structured evolution of the original 1974 Dungeons & Dragons game. Designed primarily by Gary Gygax and published by TSR, AD&D 1st Edition became the definitive version of the game throughout the late 1970s and 1980s.
Most importantly for Dragonlance fans, AD&D 1st Edition was the rules system for which the original Dragonlance adventures and novels were created.
If you are exploring the roots of Dragonlance, understanding AD&D is essential.

Why AD&D Was Created
By 1976, the original D&D rules had expanded across multiple supplements and magazine articles. The system had grown fragmented and inconsistent. AD&D was created to:
- Reorganize and codify the rules into a unified structure
- Expand mechanical depth and detail
- Create a standardized ruleset for tournaments and organized play
- Provide a more “official” framework to reduce house-rule variance
AD&D was presented not merely as a revision, but as a distinct and more comprehensive game system.
The Three Core Rulebooks
AD&D 1st Edition is defined by its three hardcover core books — the first hardcover rulebooks in roleplaying game history.
Monster Manual (1977)
The first AD&D release, published in December 1977.
- Over 350 monsters
- Expanded stat blocks (frequency, intelligence, alignment, magic resistance, etc.)
- Nearly 200 illustrations
- The first RPG hardcover ever published
- Introduced devils, new dinosaurs, mimics, otyughs, xorn, and more
Though technically labeled AD&D, it was initially used with older D&D rules while the rest of the system was still being completed.
It set the tone for AD&D’s design philosophy: more detailed, more specific, and more expansive.
Players Handbook (1978)
Published in June 1978, this book introduced:
- Ten core character classes (cleric, fighter, magic-user, thief, druid, paladin, ranger, illusionist, assassin, monk)
- Expanded races including gnome, half-elf, and half-orc
- The nine-alignment system
- Spell components and more detailed spell descriptions
- Psionics rules
Unlike modern editions, the Players Handbook did not contain full combat or saving throw rules. Those were reserved for the Dungeon Master.
This reflects AD&D’s philosophy: the Dungeon Master was the final authority and primary rules-holder.
Dungeon Masters Guide (1979)
Published in August 1979, this completed the AD&D rules system.
- Combat rules (segmented rounds, weapon speed factors)
- Saving throws and attack matrices
- Experience point tables for monsters
- Magic item descriptions
- Random dungeon generation tables
- Encounter charts
- Extensive appendices
Notably, Appendix N listed the fantasy authors who inspired AD&D, including Tolkien, Howard, Moorcock, Leiber, and others — a foundational reading list for fantasy RPG enthusiasts.
The Dungeon Masters Guide functioned as the true mechanical core of AD&D 1e.
Key Mechanical Changes from Original D&D
AD&D 1e differed from earlier D&D in several important ways:
1. Nine Alignment System
Expanded from earlier models into:
Lawful Good, Neutral Good, Chaotic Good
Lawful Neutral, True Neutral, Chaotic Neutral
Lawful Evil, Neutral Evil, Chaotic Evil
This alignment grid became a defining feature of classic D&D.
2. Expanded Character Power
- 4d6 drop lowest for ability scores (in some methods)
- Higher level caps
- More class abilities
- Greater spell variety
3. Detailed Combat System
- Segment-based rounds
- Weapon vs. armor modifiers
- Weapon speed factors
- Spell interruption rules
While many groups simplified it, the system offered unprecedented tactical depth.
4. Monster Design Evolution
Creatures were no longer simple stat entries — they had ecology, behavior, alignment, intelligence, and lore. This shift shaped how fantasy monsters were portrayed for decades.
AD&D and Dragonlance
Dragonlance was created specifically for AD&D 1st Edition. The original DL adventure modules, beginning with DL1 (1984), were written for AD&D mechanics.
The world of Krynn — its dragons, clerics, gods, and alignment conflicts — is deeply rooted in AD&D’s rules structure:
- The nine-alignment system shaped the moral structure of Krynn
- The clerical magic rules supported the return of the gods
- The detailed dragon statistics defined the War of the Lance
If you are exploring Dragonlance history, AD&D 1e is the mechanical foundation beneath it.
The Legacy of AD&D 1st Edition
AD&D 1e dominated tabletop fantasy gaming from 1977 through the late 1980s. It established:
- The three-book core format
- The Great Wheel cosmology
- Tournament play standards
- Expanded class identity
- The template for hardcover RPG publishing
In 1989, AD&D transitioned into 2nd Edition — but 1st Edition remains iconic for its depth, eccentric organization, and uncompromising Dungeon Master authority.
For many fans, it represents the golden age of tabletop fantasy gaming.
