Basic, Expert, Companion

Dungeons and Dragons has a long and proud history. The one most people are familiar with is Advanced Dungeons and Dragons (or AD&D). If asked, most fans of the game would list the history of the game as:

  • Chainmail: a set of combat rules; proto-role-playing. Primarily a war game.
  • Original Dungeons and Dragons (OD&D): the original true role-playing game. Heavily rooted in its war-gaming past.
  • Advanced Dungeons and Dragons (AD&D): E. Gary Gygax's magnum opus. The three books which make up this version of the game are the points to which all other games point.
  • Advanced Dungeons and Dragons 2nd Edition (AD&D 2e): this is the version of the game designed by the people at E. Gary Gygax's company after they kicked E. Gary Gygax out of it.
  • Dungeons and Dragons 3rd Edition (D&D 3e or the d20 System): after Tactical Simulations Rules (TSR) folded and was purchased by Wizards of the Coast, this was the version of the game that resulted. The d20 System was the core of those rules presented in a way that could be used by other companies to make compatible material.
  • Dungeons and Dragons version 3.5 (D&D 3.5 or the d20 System 3.5): it was not long after that a revised version was released. I am still confused as to why this was a point-five release, as opposed to a point-one, or a revised edition.
  • Dungeons and Dragons 4th Edition (D&D 4e): the final version (thus far) of the Dungeons and Dragons line. A new edition -- called Next Edition currently -- is slated to be released sometime soon.

But there is another. When Advanced Dungeons and Dragons was released, there was also a set of rules edited and revised by Frank Mentzer. This set of rules was not released in a series of hard-cover volumes; instead, it was a series of boxed sets, each building on the previous set. This version of Dungeons and Dragons, sometimes called B/X, or BECMI, remains the most beautiful set of rules for the Dungeons and Dragons line ever produced.

Frank Mentzer took rules core as written by E. Gary Gygax and Dave Arneson, and created the Dungeons and Dragons Basic Set. This box included a Player's Manual, a Dungeon Master's Rulebook, and some additional material to get the new gamer started down the road to a lifelong hobby of the imagination. But, this basic set was nothing more than an appetizer. The rules would work for your game group for a few months at the most! Character creation was described, and the earliest levels of advancement were handled. Once your character reached 3rd level -- someone who starts to show some real promise -- you have reached the limit. You cannot go any further.

The Dungeons and Dragons Expert Set takes over from there. This box set had rules covering characters from 4th level to 14th level (arguably, the meat of the adventuring career). More monsters, more spells, more weapons and equipment... this set contained things that the players may not have considered prior such as adventuring in the wilderness as opposed to the dungeon settings prescribed in the Basic Set, or mapping that same wilderness.

Where Advanced Dungeons and Dragons throws the whole of the world in your face and expects you to trim it down to the relevant sections for your group, Basic introduced role playing as a concept, then expands upon it in the Expert set to include new forms of adventure. But the Basic-Expert -- or B/X -- rules did not stop here! There is a lot that ca still be done... and for that we reach the Companion rules!

The Dungeons and Dragons Companion Set covers levels 15 to 25; it introduces new forms of adventure, new forms of combat, and gives advice to the players and the Dungeon Master on how to create and rule your own lands. The character paths diverge from those that remain landed to those that choose to roam the lands, continuing to seek adventure and the unknown.

  • Are you a cleric? Clergy can settle down to establish a church and rise within the theocratic hierarchy... or they can leave the administration of the church to others as they wander the lands spreading the word to the multitudes.
  • Are you a fighter? Fighters can settle down to establish a dominion and rise within the noble ranks... or they can forsake such duties and become a Paladin, a Knight, or an Avenger.
  • Are you a magic-user? Magic-users can settle down as a wizard or maga to establish a tower attracting young pupils seeking arcane knowledge... or they can wander the lands as a magus gathering information and rumor as they go.
  • and so on...

I cannot stress this enough:

E. Gary Gygax (Advanced Dungeons and Dragons) focused almost entirely on the game mechanics of high level characters: when you reach level 'X', you get access to special ability 'Y' and can cast spells from list 'Z'.

Frank Mentzer (Basic + Expert + Companion) gave you rules for advancement, but spent the bulk of the text on the role playing ramifications of high level characters: when you reach level 'X', the possibilities of establishing yourself as a hero of type 'A', 'B', or 'C' (as discussed below) are open to you...

This is what made Frank Mentzer and his almost forgotten line of Dungeons and Dragons history so beautiful: simple organization, staggered implementation, continued advice. Nothing like what is seen in the Companion Set existed in AD&D. Sure, AD&D gave costs for strongholds and the like; but these rules were given no more consideration than any other rule. The mechanics were described, but word on implication was left devoid. The rules were packed into the opaque density of the Dungeon Master's Guide without fanfare, and left unmarked to be discovered whenever a Dungeon Master had the fortune to see them.

Frank Mentzer's approach was organic. You start here. Once you have those concepts mastered, we will move on to these concepts.Ad astra.



The Basic Set gave you the core rules. The Expert Set expanded upon these rules.The Companion Set expanded upon the concepts and implications of high level characters. The Master's Set was the culmination of everything. In this boxed set we found:

  • master combat options
  • high-level spells
  • extremely-high level monsters
  • a multitude of character options
  • character advancement from level 26 to 36

Once you had things like character roles and responsibilities established -- the sorts of things that do not require rules, but need a steady hand at adjudication while playing the game -- as they were in the Companion Set, the Master's Set returns to the realm of rules to look at highly advanced and specialized combat options; spell options; an so on.

In the Master's set, weapons cease being a one-or-two handed weapon dealing 'X' damage. they take on a role in-and-of themselves, with options indicating how that weapon is used in combat when fighting an unarmed foe or when fighting an armed foe. The options were seemingly limitless!

One can ask why these rules did not exist in the Basic, Expert, or Companion sets. And this is a valid question. There is nothing inherent about the rules which prevent them from being used in lower level-games. IN fact, once you have the Master's Set, the rules for weapon training and specialization are certainly usable by characters just starting out in the Basic levels or advancing through the Expert or Companion levels.

But there is something about them that requires that you -- the player and the Dungeon Master -- have a firm grasp of the core rules before you attempt to use them. Combat, as presented in the earlier box sets, was quick and deadly. One or two dice rolls each round was all that was needed. A fighter need only decide whom his target would be.

With the combat options presented in the Master's Set... the fighter needs to decide who his allotted number of parries would be assigned to, who would get the benefits of his potential knock-out blows, and so on. The battlefield becomes rife with dramatic descriptions and potential combat flair!

Again... nothing like this existed in Advanced Dungeons and Dragons. Nothing at all.



The final chapter in the BECMI (Basic + Expert + Companion + Masters + Immortals) saga, is Wrath of the Immortals. This was a set that transcended epic-fantasy and went for the ultimate prize: immortal power.

The books in this set offered you the opportunity to cease playing in the petty wars and squabbles of mortal kingdoms, and instead start playing with mortals as so many pawns on the celestial chessboard. You were to rise and become a demi-god, a being of such frightful power that the ideas of attributes and character level started to become blurry and unimportant.

Advanced Dungeons and Dragons gave us the book Deities and Demigods which reduced most gods, goddesses, and god-like beings to the stat-block used for monsters in the Monster Manual. Zeus became a 400-hit point monster. A powerful monster, sure... but nothing more. Advanced Dungeons and Dragons had missed the mark and was far less advanced in its approach than BECMI.

Immortal beings in BECMI were awe-inspiring powerful. And thanks to the Frank Mentzer and his team, manageable. You could play as an immortal, even gain power as an immortal, all while having stories and adventures that challenged you on the level at which you were playing the game. From political intrigue to combat -- these books had the ability to show the Dungeon Master how to run those games without them devolving.

The key was advice. You can hand a Dungeon Master a set of rules, and expect them to follow them. But you cannot set rules for everything a creative player can come up with. So, the game -- at all levels -- focused on the game play as a concept and gave guidelines for how to use, stretch, apply, and modify those rules to suit the situation.

It was, and will ever remain, the best Dungeons and Dragons has ever had to offer.


Rules Cyclopedia

In 1991, TSR released a hard-cover edition of the BECMI system. This book, called The Rules Cyclopedia, took all of the material from Basic, Expert, Companion, Masters and Immortals and re-organized them into a cohesive whole.

  • All of the combat rules -- basic combat, advanced combat options, weapon training and specialization -- put into a single, comprehensive whole.
  • All of the spells -- low, mid, and high-level -- placed into one chapter and ordered properly.
  • All of the monsters -- one chapter, organized alphabetically.
  • High Level campaigns... dungeon and wilderness mapping... advanced character options... immortals rules.... all of it.

This book was compiled and developed by Aaron Allston, one of the guys most responsible for the Immortals books. This book has its flaws, but overall, it is an amazing feat. This book has more relevant material for a player or Dungeon Master packed into 300 pages than the entire Advanced Dungeons and Dragons line. And I really do not care which edition you are discussing.

Limited Edition?

Should the BECMI rules get a Limited Edition treatment?

  • Yes -- a limited edition mega-box of the original saddle-stitched books should be produced.
  • Yes -- a limited edition Rule Cyclopedia should be produced.
  • Yes -- a limited edition mega-box, and a limited edition Rule Cyclopedia should be produced.
  • No -- a limited edition of the BECMI rules should not be produced.

What is the point to all of this?

Other than shining a light into a dark corner of the Dungeons and Dragons historical timeline, why did I write this? Why should you care? The point is simple:

Wizards of the Coast, the company that currently owns Dungeons and Dragons and is in development for Dungeons and Dragons Next Edition, has (in the mean time) produced special high-quality reprints for...

  • Original Dungeons and Dragons -- a beautiful wooden box with the digest-sized volumes that made up the old rules that launched a revolutionary new hobby.
  • Advanced Dungeons and Dragons -- with faux-leather covers and beautiful gold-leaf paper, the original Player's Handbook, Monster Manual, and Dungeon Master's Guide have been reproduced. These were later followed up with Unearthed Arcana (a book that expanded the number of spells and such, but offered little else of use), and even a group of adventure modules in the format. All books included all known errata.
  • Advanced Dungeons and Dragons 2nd Edition -- again, gorgeous in their reproduction, these books cover the core three books. They did not get faux-leather covers, but were masterfully produced. All books included all known errata.
  • Dungeons and Dragons version 3.5 -- using the artistic style that defined the 3.x editions, these reproductions of the core books (as er AD&D and AD&D 2e, above). A few other volumes were include such as the Spell Compendium and the Magic Item Compendium. All books included all known errata.

There appears to be no plan to give the BECMI editions a limited edition treatment. And I find this not only sad, but incredibly disrespectful to the game's history, Frank Mentzer, and the Dungeons and Dragons brand.

While I think doing a mega-boxed set of the original saddle-stitched books would be great, the more practical approach would be to do a special limited edition of The Rules Cyclopedia. Several websites have collected all of the known errata -- so production of this volume would not be particularly difficult.

What appears to be lacking is the will. What appears to be lacking is the respect.

For years, the people who played and enjoyed BECMI were seen as playing an inferior game. Advanced Dungeons and Dragons, it was claimed, was the Basic set with the training wheels removed. Advanced was the better game, they would claim.

I am here to tell you that they were wrong. BECMI was a different approach to fantasy role-playing. Advanced Dungeons and Dragons was different, it was not better. I even hope I have made a cast that, perhaps, in some ways, Advanced Dungeons and Dragons was inferior. Regardless, it deserves the same respect given to the other versions of the game.

It's time Wizards of the Coast made a masterfully produced, limited edition copy of The Rules Cyclopedia. In fact, it is overdue.

So would it be safe to say that he almost created his own game but in the same world. I have respect for all RPG's as they all have their ups and downs. If it is playable and makes sense I am always willing to try it out.

BECMI was, is, and always will be the best version of the Dungeons and Dragons game. I can still read the manuals with interest and they still fire up my imagination. The last few editions of D&D completely fail to capture my attention. The complexity of BECMI D&D emerged from a seemingly simple concept. Begin by killing the minions of evil in the dungeons, adventure out into the wilderness, build and empire, encounter gods on the outer planes, then ascend to immortality. The Immortals Set even contained rules for WINNING the game. Although, in order to win, you had to go through all of existence twice (which would have taken at least ten years of regular play). To this day, Mentzer himself has never heard of anyone doing this. I'd love it if a BECMI 2nd edition was published. It wouldn't even have to be dungeons and dragons, it would just have to follow the same campaign progression, culminating in the politics of the immortals. I'd create and publish this game system myself if I had time!
