Theorems & Thaumaturgy: Revised Edition

In January, I briefly mentioned that I've been working on a revised edition of Theorems & Thaumaturgy. It's been a stop and start effort, in between working on Wormskin / Dolmenwood stuff, other writing projects (e.g. the B/X Warrior), and real life. But: today, I reached a very big milestone. The layout is done! I still have a couple of small formatting issues to figure out (like how I want tables to look), but all of the text is finished and all of the spreads are laid out. It comes to a total of 135 pages (A5), including the OGL and table of contents. I'm very pleased with how it's looking.

I'm now discussing illustration, so far with Cadanse, who did a lot of the illustrations in the original edition, and also with another artist.

For the interest of readers, I thought it'd be nice to write an overview of the differences between the original and the revised editions:

  • Expanded introductory material, including suggested rules for spell acquisition (in Basic and Advanced style games) and guidelines for the existence of specialist wizards in a campaign alongside standard magic-users.
  • Three full classes: the elementalist, necromancer, and vivimancer. The text has been revised and clarified, where necessary.
  • The "variant classes" (the fey elf and expanded illusionist) have been removed. This content will see the light of day again in another form. (I hope to do massively expanded versions of both, at some point.)
  • The elementalist spell list has been expanded (it looks like there are 8 new spells, on a quick scan) and updated to correspond with the list from the (eternally) work-in-progress Complete Elementalist. As an example of the latter, the spells summon elementine and banish elementine are now combined.
  • The necromancer spell list is largely unchanged. I moved a couple of spells (detach/graft and organ transference) to the vivimancer, as they felt more fitting there.
  • The vivimancer spell list has been updated to correspond with the list in The Complete Vivimancer. For example, the spell vats of creation is now 3rd level, rather than 7th, as it was in the original Theorems & Thaumaturgy. I don't think I added any new spells.
  • All three classes now have a dedicated magic items section, containing 8 items each. For the necromancer, this is no change, but for the elementalist and vivimancer, this means... 8 new items (there were no elementalist or vivimancer magic items in the original edition). (A side-effect of this reorganization is that the few magic items which aren't related to one of the three classes are no longer included.)
  • The tomes section has been completely removed. Again, I plan to make this content available in some form, but felt that it's not a necessary and integral part of this book.
  • Likewise, the lists of example memorized spells have been removed. I'll certainly publish these as a little add-on PDF, for those (DMs, I suppose) who want it.
  • The small appendix with alternative rules for magic use is no longer present.
  • The monsters section has been slightly trimmed to only include the monsters which are directly related to one of the classes (via conjuration/summoning spells). I think this caused about three monsters to be removed.
  • All of the spells are now classified with their school(s). I like spell schools. Even though they're not an explicit part of Labyrinth Lord, their inclusion in the book adds value for DMs who like to use them.
So, overall, the new edition is much more focused. The original edition had a kind of grab-bag quality to it, which I came to dislike, over time.

I can't place a schedule on when it'll be ready, as I don't know how quickly illustration will work out, but I think it's pretty safe to say it should be published by the autumn.

An A5 Theorems & Thaumaturgy. Whatever next.


  1. Can't wait! Please keep making the Theorems & Thaumaturgy/Complete ... books, along with your B/X ones... Great stuff! Will look into your new Wormskin/Dolomwood campaign stuff as soon as I can. Keep up the great work :)

    1. Theorems & Thaumaturgy Revised is almost finished now. Just waiting for the last few illustrations. A November release seems realistic. I've also got the B/X Warrior almost finished. Should be a bountiful winter of publishing!

  2. Thanks :) You just made my day! Any b/x treatment for mages and priests in the works? How about mutants and technology? Have you ever considered a time mage/chronomancer for Labyrinth Lord?

    1. I've got some ideas for a B/X Wizard book. I've also got ideas for a whole B/X variant based around these chararcter creation ideas, though, so I might end up just rolling the wizard ideas into that. Time will tell...

      A chronomancer is certainly something I've considered. Also a dimensionalist. And an expanded illusionist. All three ideas overlap, to some degree.

      Kind of techno-fantasy type stuff isn't so much my thing (though I do love post-apoc, as a genre), so I guess probably nothing in that vein is forthcoming ;)
