OD&D Attack Progressions Compared (Originals and Clones), Part I

Moldvay Basic
A comment on the last blog post made me want to do this.

Here are the attack progressions to hit Armor Class 2 by level for ten games--the three major OD&D versions and seven contemporary clones:

Dungeons & Dragons (0e) (1974-78)
Advanced Dungeons & Dragons (1e) (1979)
Moldvay Basic/Cook Expert Dungeons & Dragons (B/X) (1981).
OSRIC (2006)
Labyrinth Lord (2007)
Swords & Wizardry (2008)*
Swords & Wizardry White Box (2009)*
Lamentations of the Flame Princess (2010)*
Seven Voyages of Zylarthen (2013)*
Delving Deeper V4 (2014)

Those with an asterisk list things in attack bonus form rather than table form, but for the sake of this comparison all will be listed in table form.

For OSRIC I used version 2.2. I assume the numbers are the same across all versions but I may be wrong on that. For Swords & Wizardry I used the recent 'Complete' edition, which may or not have different numbers from the original 2008 edition. The numbers for Delving Deeper are from the most recent edition, which differ somewhat from those of earlier editions.

I hope I didn't make any mistakes.

Looking at the tables a number of things leap out. Some things were not surprising. Some were.

I'll make some comments tomorrow. But I welcome any comments or observations anyone would like to make.

(If you turn your phone sideways, I think these will exactly fill up the screen. You probably already knew that. But I didn't.)

  1. Fascinating. I noticed that you did not use the Holmes version in your comparisons. Was this on purpose? It is not a large matter just an observation.

    1. Holmes only covers levels 1-3, and is the same as OD&D for those levels - all classes need a 17 to hit AC 2. The most notable addition to Holmes over OD&D is a new line for "Normal Man", who needs an 18 for AC 2 (that is, attacks at -1 as compared to L1-3s).

    2. Thanks. Very enlightening and now understandable in light of it.

  2. Excellent use of old-school (Moldvay I think) table art.

  3. I learned years ago that even within similar D&D rule-sets, there are a lot of small differences within the charts and tables, but you only notice them when you jump form one system to the other. And even still, you'll most likely stumble upon them as you are running the game.

    For example, there are slight changes in the saving throws between the Basic and Expert sets, and the Companion and Masters sets make drastic changes to them, so by Rules Cyclopedia, they retroactively change the whole array! All over, this applies to To-Hits, Saving Throws, Spells/day, etc., et al.!

    Also, drafting a system that adjusts the "EXP Needed" based on class capability is a mess when its just covering one rule set -- you'll get no conformity between the different rule sets, so you'll have to treat each system with their own formula, and their would still be some compatibility issues!

    It would be nice to have a master list of all the charts and tables between all the classic editions and the (retro/near-)clones that spawned from them, for the sake of conversions.

  4. The hidden secret here is: Use the best weapon and armour available to your class.

  5. Oh, you missed a Holmes clone, there. ;-)

    1. I didn't look at Holmes or his clones because the numbers track 0e and of course they only list the first three levels, so there is no progression.
