Grimoire of Lost Souls

Lure ancient spirits to bargain for their supernatural power.

Immerse yourself in the ancient rituals and legends of pact magic. Grab thick chalk, gather totems, inscribe a geometric sigil, and invoke the name of an inchoate and terrible spirit from the Dark Beyond to aid your quest.

Behold! With a final flourish, you surrender to the spirit and a quivering surge of power emanates from deep within. Are you ready? Follow paths once trodden by shivering demons and martyred titans, lost mortals and chastised gods. Within this occult pages, the vestiges of 144 sundered souls lie at your fingertips, yours to command if you dare.

You will discover:

  • The pactmaker class with access to binder secrets.
  • Archetype options to integrate pactmaking into 30 popular classes.
  • Feats, spells, and magic items suited to binding of spirits.
  • One hundred forty-four bindable spirits from across the ages. Each spirit includes a legend, granted abilities, and more.
  • Six prestige classes, seven organizations and three alternate planes of existence well-suited to occult adventures.
  • Occult creatures, pactmaker background generator, pact maladies, dangerous ravager spirits, and more.
  • Ideas for GMs to integrate pact magic into their campaign settings.

Really needed to get this PoD on here. Paizo's got that physical copy on a seemingly perpetual back-order and I'm not going to risk buying it there, because I don't a purchase waiting in limbo indefinitely.

I can't be the only one who feels that way about it...

Paizo is finally asking for copies to fill all of the book orders. Community with them now! Hopefully better late than never for you.

I see this was a year ago, but any chance there are still some printed copies available? I would definitely pick up a physical copy if I could find one in stock. Thanks.

You miss a lot of sales I think.... Shipping from paizo to europe is a lot more expensive than from here...

I'd love to get this in hardcopy, but right now it's listed as Backorder on the Paizo website. It'd be great if this was available here for Print on Demand, especially now that it's a lot harder to get. And... the pdf is just super expensive for a book to just be a pdf.

For Europe, the shipping is too expensive from Paizo... Shipping postal delivery : $31.56 ... You'll open a full new market if you sell the hardcover from drivethrurpg !

I was wondering when of if this awesome book will be Print on Demand. Unfortunately I missed the kickstarter by a long shot but when the pdf became available i immediately bought it. Sadly I have a hard time loading the pdf but definitely don't regret my purchase due to the awesomeness that is this book.

Thanks in advance for getting back with me and thank you guys for bringing this material to Pathfinder!

If at all possible, please make or contract someone to make Hero Lab files? Thank you!
And no, I can not make Hero Lab files or the request would have been worded differently.

I have a few questions for you.
a) Why doesn´t the cover include the Pathfinder Compatible logo, seeing that it is for Pathfinder - and your past Pact Magic books were?
b) The link to your homepage, seems to say the least.. Off.. Do you have a homepage?
c) Are you any wiser as to when the hardcover book will be out?
d) Villains & secrets of Pact Magic, are they also included in this book? It seems to me, they are not, or at least loads are left out. Is this true?

I've bought this great book.
Many people says it's overpriced but I say otherwise.
Layout was great. amount of words alone are overwhelming to read( a lot of source you could use). Good artwork.
It was worth buying as well as worth waiting.
I wasn't able to support kickstarter but happy to support two writers through buying this book on DTRPG.

I would like to clarify something.

I personally didn't say it was overpriced. I said that I had already bought the four other previous pact books, which at today's (9/26/2016) price, is $50. The author confirmed that having those four means I have ~ 75% of what it is in this book. Therefore, what I asked for was a discount for already having purchased much of this content.

Having said that, I reiterate that I do agree that new packaging, updates, new art, and combined into one book have value. I just haven't decided yet if they have full value **to me**.

It's your call man.
Customer avatar
Jonathan G September 27, 2016 1:38 pm UTC
Daniel J, how about a little more information to help me make that call?

Did you buy all of the previous items? If so, how does it compare? Would you say paying for a lot of the material again was worth it? If not, can you give a rundown on what it has, what you like, and how you plan to use it or are using it in your games? Or review it with more than a paragraph?

Again, I didn't say it was overpriced. I agree that they should be compensated for their work. If you like it, sell me on it! Please!

Yes. Lightning Source is currently processing it for printing now. We hope to have it available in the next few weeks.

Why on earth is there not a discount for this product if we've already bought pact magic unbound? I'm not paying 50 canadian for an update on a product I already own.
Customer avatar
Jonathan G September 16, 2016 1:31 pm UTC
I agree so much. I have all four of the Pact Magic books (Vol 1, Vol 2, Villains, and Secrets) and now they want full price from me for the update? I get that they deserve to be compensated for the work they have done. I'm not against that. But this isn't a new book for me, it's a supplement to give me the updates to books I already own. I will be mad if I have to pay full price. I guess I will watch to see if it goes on sale at some point and decide then.

If you only have PMU 1, then you have *maybe* 1/4 of the content in this book.
If you have PMU 1 and PMU 2, then you have *maybe* 2/3 of the content in this book.

As the guy who wrote it, believe me. Everything was rewritten basically from scratch. Everything was updated and reorganized. New bits were added pretty much everywhere. This is not "just an update."

But its your money—you're free to do with it as you please.

@Jonathan G
If you have all four of Radiance House's pact magic books, you probably have roughly 3/4 of the content in this book, but that content isn't all converted for the Pathfinder Roleplaying Game, wasn't written and balanced by a well-known freelancer and several months' worth of open playtesting, and doesn't have the polish or full-color artwork that the Grimoire of Lost Souls has. I wouldn't count on a sale any time soon. Personally, I wouldn't be mad, because in my opinion this is as different from all of the books you own as the Pathfinder RPG Core Rulebook is from the 3.5 PHB and DMG, and saves you about as much work. Plus the book is GORGEOUS (there should be a preview up on this page).

But of course it is your money and you should do whatever you feel is best for you and your finances with it. If you want to update the content in your books yourself, please be advised that it took Dario and I together roughly two years to rite everything in the Grimoire of Lost Souls and update...See more

Okay! Thanks for the reply!

A few points for you, then.

a) update the preview with the cover, or some other art, and at least partial table of contents. I don't think the preview above gives me enough to see your point on the art or extra material.

b) I think you need to replace "All classes, spirits, etc are entirely rewritten from the ground up" with what you have said above in your reply to me. I didn't get the above points from that one sentence. That would have helped explain to me why it would be worth it and the effort.

As I said, I think artists/creators should be paid for their effort. Having explained it to me, I understand and am more willing to pay for it. What would get me to pay for it again is a (Strands of) Fate version! :)

Overall an improvement over earlier iterations of the supplements, it brought back some features Secrets of Pact magic, improved spirit scaling so you can be an 'evocation occultist' if you really wanted to and quashed much of the more broken stuff pact magic could do like crystalized pain and simulacrum abuse.

Some complaints I have are over the name of the updated class, since paizo stole the name occultist 100% coincidentally trust me, the occultist has become the 'pactmaker.' Another complaint that ought to be fixed is the shear amount of gibberish in the book, lines of text will be replaced by random strings of characters. And lastly, I'm happy to pay almost 40 bucks for the product but it's a bit on the pricy side.

Overall 4/5 would not buy again because it's 40 bucks, but it's a great supplement.

Thanks for your review! I would appreciate it if you made it formal so we could have a star rating on the product—every bit of attention helps.

Also, sorry you don't like the name pactmaker. It wasn't my first choice, but we let our Kickstarter backers vote and the name fits what the class does, so I'm alright with that personally. There's a nifty sidebar in the Introduction that has a list of potential alternate names for the class if you don't like the name pactmaker for your home games—we just won't be using any of those alternate names in official publications.

Original electronic
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.
