deconstruction of od&d ability scores and their effects

-

Surprise! You get some proper punctuation because I originally wrote this in a Word document.

In OD&D, 3d6-based effects are tied together under a particular ability score.

  • Maximum # of Hirelings and Hireling Loyalty Base as Charisma
  • System Shock Survival and Extra Hit Points per Hit Die as Constitution
  • Missile To-Hit Bonus and Initiative Bonus as Dexterity
  • Mage XP Bonus and Extra Languages Known as Intelligence
  • Fighter XP Bonus as Strength
  • Cleric XP Bonus as Wisdom

In each of the tables that follow, the most average scores [9, 12] are highlighted.

By wrapping up these 10 different effects into the 6 abilities, the Dungeons & Dragons game establishes character archetypes. Since most effects of ability scores only take place for those with scores outside of the middle ~50%, with the notable exception of system shock survival [1], the expectation is that characters will have 3 average abilities (with effects) and 3 abilities (with effects) significantly below or above average. This means that the categorization of effects by abilities, besides solidifying character concepts, also helps limit the extent to which randomization affects player experience. Perhaps it also relates to there being three classes, and so a player can get an even if asymmetrical mix of ability scores applicable for XP bonuses and/or more practical effects (e.g. initiative bonus).

Keep in mind that for XP bonuses:

  • Clerics can treat every 2 points of Intelligence past 8 as 1 point of Wisdom.
  • Clerics can treat every 3 points of Strength past 8 as 1 point of Wisdom.
  • Fighters can treat every 2 points of Intelligence past 8 as 1 point of Strength.
  • Fighters can treat every 3 points of Wisdom past 8 as 1 point of Strength.
  • Mages can treat every 2 points of Wisdom past 8 as 1 point of Intelligence.

The lack of a Strength-to-Wisdom 'conversion rate' for mages shows that players were more likely to play as either clerics or fighters, whose Strength/Wisdom conversion rate is the inverse of each other.









[1] This means that system shock survival was not only viewed as significant by the authors of the rules, but it was expected to significantly affect even (or especially) the average player.

    Shall we make a character sheet with these detached characteristics in place of the abilities, and also write up a one-page for rolling the actual values rather than the 3d6 scores which won't mean anything in this deconstructed version?

    It could be a fun, 'what-if', experiment.

      that would for sure be fun! would offer i think a different way of thinking about your characters :)

    You lost me when you wrote, "...the categorization of effects by abilities... also helps limit the extent to which randomization affects player experience." How so? I think there's something obvious I'm missing here.

      it limits randomization since instead of there being ten random scores, each with one effect, the ten effects are wrapped into six categories. so only six numbers are generated, instead of ten, reducing the randomness of the effects in general.

      on the flipside, though, you could say that this makes each effect more subject to randomization since multiple effects are determined by the outcome of one score.

      I'm in favour of randomising all ten factors; complete deconstruction.

      Ah, ok, thanks! I wasn't quite making the leap there, but yeah, I see what you're saying. And then, yes, the groupings would dictate your role in the party; by focusing a single random result across multiple results means that you don't end up with a character who's really good at one thing, but not at the other things that would go with that role. And, looked at that way, it's easy to see how you could rearrange things to basically create what is, effectively, class from just your stats.

D&D Fifth Edition: Death & Rebirth

Hashtag OSRisOverParty, Hashtag RIPBozo, etc etc. The initial… “edition” of Dungeons & Dragons, Fifth Edition tried to present itself as a reactionary return to some ideal past paradigm of D&D —be it Third Edition to win back territory lost prior to Paizo’s Pathfinder , or an even older Gygaxian edition to get in the pants of the sort-of nascent OSR. Practically, this resulted in a final product that was like a simple Third Edition with dogwhistle-like nods to OSR conventions (since the play-style’s influence in the end was tenuous at best and mostly abandoned after the public test phase). It’s maybe more succinctly described as a people-pleasing game, with the caveat that people-pleasers don’t please anyone. So, how did it become popular? And how does the new 2024 not-edition reflect major differences between then and now, in terms of how D&D is perceived and played? This is my ramble. Sent from iPhone. Fifth Edition: Born in 2014 Of course, nobody plays D&D as ...

OSR Rules Families

So, here’s the thing: originally I wrote this like a fucking research article with a hypothesis, a methodology, and all that stuff. I’m not even a scientific research person. That’s my partner’s job. Not mine. So, instead of walking you through every single step I took, I’m going to take the journalistic approach and start with the big picture before I zoom into it and tell you about the little details. I read, reviewed, and statistically organized 38 different rulebooks considered to be OSR or OSR-adjacent. These include four rulebooks from TSR-era Dungeons & Dragons , as well as ten rulebooks from the 2000s and 2010s. The remaining 24 rulebooks postdate the closure of G+ in early 2019. Please refer to the bibliography at the bottom of this post for more information. After having collected and organized a dataset with ~90 variables, I found the statistical similarity between each pair of rulebooks based on that data. Finally, I ran an algorithm to determine clusters of these bo...

Bite-Sized Dungeons

Workbook Now Available On Itch! Bite-Sized Dungeons by Traverse Fantasy Edit: This whole time, I said that a first level dungeon hoard had 100 times d6 gold pieces when it actually has just 10 times d6. This means the average hoard has an XP value of 70 without gems, or ~110 with gems. By extension, the eighteen-room dungeon only has 350 XP without gems, or ~550 XP with gems. That is downright dismal and I don’t think works out with modern play sessions and party counts, so let’s pretend it said 100 times d6 anyway. I just read an article by Yora of Spriggan’s Den about extrapolating a scheme for an eighteen-room dungeon from the procedural generation rules in B/X (1981) [1]. As Yora points out, eighteen rooms is a great size for a mid-to-large dungeon or for a floor of a multi-level dungeon, and the checklist of rooms makes it easy to make sure that the final product has a variety of interesting play interactions. But, being as large as it is, it can still be a tall order on the ...
