Magical Theorems & Dark Pacts


Promote Your Magic User!

Magical Theorems & Dark Pacts contains everything you need to run a spellcaster in Labyrinth Lord and other basic fantasy OSR games. For completion, this tome includes the three core spellcasting classes, and adds ten more, along with full rules for all their assorted spells. 


Chapter 1 – Classes

  • Cleric (warrior-priests)
  • Wizard (classic magic-users with 10 levels of spells)
  • Elven Swordmage (elves from the core rules – arcane warriors)
  • Elven Warder (wilderness elves, guardians of their kin)
  • Enchanter (artists, con-men, and masters of… duh… enchantments)
  • Fleshcrafter (twisted magic-users that work with flesh)
  • Healer (compassionate and tough hearth-healers)
  • Inquisitor (ecclesiastic investigators and master intimidators)
  • Merchant Prince (elite merchants with spellcasting support)
  • Necromancer (you know exactly what these guys do)
  • Pact-Bound (magic-users who sell their souls for power)
  • Theurge (divine casters who learn from liturgical texts)
  • Unseen (thieves with an innate knack for magic)

Chapter 2 – Spells

All the spells for all these classes are included (including the core spells from Labyrinth Lord).


Chapter 3 – Magic Items

28 pages of new magic items generally aimed towards spellcasters (with a few sneak ones thrown in for the Unseen). From new and unusual potions to exotic rings and a collection of new figurines of wondrous power, this chapter also focuses on making magic items unique in your game - avoiding the pitfalls of every campaign having the same gauntlets of ogre power and rings of protection.

Chapter 4 – Creatures

Just a few monsters in this short chapter – one referenced earlier in the book and  rules for summoning & conjuring alternate types of elementals (wind, crystal, dungeon, wave, moss, thorn, smoke, zephyr and so on).

Finally there’s a short section on using this book with the Advanced Edition Companion. 99% of this book was written using only the core Labyrinth Lord rules without referencing the AEC at all, and therefore there are some suggestions for mixing these rules with the AEC ones – primarily adding AEC spells to the existing spell lists, and the revised hit dice for the various classes if using the optional AEC hit dice.

I have spent a lot of time with this book and discussing how to use it in your games on my blog.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
