The Solo Adventurer's Toolbox


Want to travel in a world where the fall of the dice can make things appear randomly? Get completely lost in this book with multiple quests and worlds of your choosing, without a DM. This book could even help you worldbuild for your very own campaign.

Scott Niedjela

Sick of not being able to find a game? Have a burning passion for D&D and everything it represents, but no way to indulge that passion in actual gameplay?

5e Solo Gamebooks presents The Solo Adventurer’s Toolbox. This book is the result of many months’ work and represents a complete system for generating on-the-fly, detailed, immersive solo adventures.  And by solo, we mean true solo, without a dungeon master.

The Fantasy Grounds version is now available here!

Using this system, paired with 5e mechanics, you can guide your PC or PCs solo through any adventure environment, creating meaningful adventures for them as they journey in the Forgotten Realms (or a campaign setting of your choice).

The Solo Adventurer’s Toolbox covers a variety of topics including quest generation, random encounter generation, random dungeon generation, random wilderness exploration, discovering settlements, merchants and shopping, downtime activities, random NPC generation, and systems for generating infinite monster encounters all tailored towards the solo PC.

In addition to being a go-to for solo D&D gamers, it also happens to be an excellent tool for DMs as well. The breadth of tables makes it an invaluable tool for brainstorming adventure ideas. This book, paired with your creativity, will enable you to create endless adventures for your weekly game, possibly as you guide your own PC or PCs through them. This is a one-of-a-kind product.


Chapter 1: Introduction and Overview of Chapters

Chapter 2: We examine the Question / Answer Mechanic that I have created for use with the resources in this book. This simple system allows you to gain answers to any question in the same way as a system like Mythic GM Emulator, but far more stripped down.

Chapter 3: Deals with travel, modes of travel, weather, camping, unmarked settlements and the like. A more detailed system for wilderness exploration is outlined in Chapter 9.

Chapter 4: Wilderness encounters. In this chapter, you will find a d100 table of random wilderness encounters, all with an open-ended nature so that they can be interpreted differently every time. You can use these, or you may choose to use the encounter generation tools in Chapter 14.

Chapter 5: The same as above, but for urban settings.

Chapter 6: The same as above, but for dungeon settings.

Chapter 7: Contains tools for generating quests for your solo PC or PCs.

Chapter 8: Contains tables for the random generation of dungeons and their contents.

Chapter 9: Contains tables for the random generation of wilderness terrain and its contents.

Chapter 10: Contains guidance on merchants and shopping while in settlements.

Chapter 11: Contains guidance on downtime activities for your solo PC.

Chapter 12: Contains some ideas about roleplay in the solo format.

Chapter 13: Tables for the random generation of any number of NPCs you might meet on your travels.

Chapter 14: A collection of tables designed to generate an infinite number of random encounters in any environment, and also answer detailed questions framed by the player.

Chapter 15: A slightly experimental chapter dealing with monster tactics.

Chapter 16: Contains tables to generate monster encounters, with difficulty adjusted for the solo PC. Tables are arranged by environment type and CR.

Chapter 17: Loot tables, Individual and Hoard, arranged by CR.

Chapter 18: An example of solo gameplay using this system.

The biggest plus is having all the tools you need to solo in one place. I've used a lot of system-agnostic GM-less tools and they tend to require a fair amount of additional supplementation to cover all the bases… The Solo Adventurer's Toolbox provides a complete system for playing 5e without a DM and a powerful tool for generating encounters, quests, NPC's and places of interest. Easily customisable to fit your game-world and level of desired complexity, with a consistent format that makes modifying the tables to fit your personal preference a breeze. This toolbox is an all-in-one gift to Solo Players!

Jay Davies

Essential for any DM, even if you have no interest in solo adventuring whatsoever! The breadth of tables and ideas presented in this document warrant the price of admission alone!

Aaron F.

The Solo Adventurer's Toolbox contains a plethora of resources to create adventures, worlds, and random encounters and events to fill your D&D sessions. It's a great resource for solo adventurers, but it's also a wonderful inspiration for DMs to create interesting and unique adventures for their players.

Kristina Chun

Imaginative and wide-reaching... I had problems taking breaks from solo-ing to play with friends!

John Todsen

I couldn't wait to get started on my personal campaign. I'm using a journal to keep myself honest and to keep for worldbuilding notes.

Josh Law from StrMod

Nice for a player. A must for a DM.

Patrick Higingbotham, NonZero Sum Games

What impressed me the most was seeing the question I had answered come to life. In solo play we can reach a level of detail that is very intuitive, rivalling even a group setting.

Timothy Arthur

All in all, this book is a must-have for those looking to explore the concept of solo play with D&D, within any campaign setting.

Would this work with Adventures in Middle Earth?

5E Solo G May 20, 2020 10:40 am UTC
Absolutely. Its conversant with 5e rules, and really any RPG rules, regardless of setting.

Patrick B March 04, 2020 3:10 pm UTC
Is this compatible with other editions like 1st or 2nd Edition AD&D. I use Fantasy Grounds and they came out with the 2nd Edition ruleset and I would like to use this for 2nd Edition AD&D. I'm fine using it for 5th edition, but as I want to use the 2nd Edition to play all the old Modules in 1st and 2nd AD&D

Hi Patrick. The majority of this book is system agnostic and could be used with anything. The only part that's really 5e specific are the encounter tables. But the rest of the book should be easily usable (or convertible for 5e)

it's not hard to rejigger the 5e rules (in general) to older editions for the most part, assuming you have the books. I don't have this (I have to wait a week before I can get it) but unless the book changes everything, this shouldn't be that big a deal.

Is there any way we can get a physical copy of this? Either permission to have it done at a print shop for our own personal use or a POD option?
Customer avatar
5E Solo G February 27, 2020 9:12 pm UTC
You absolutely have my permission to get it printed. It won't be getting a POD unfortunately as I can't really justify the time involved. I've done one title as POD and I think I've sold like 5 copies over the last two years. The time and effort it takes to get it to POD is pretty immense - back and forth with the printer endlessly.

Hey Paul.

Question re Solo Adventurers Toolbox. On page 49, in the room contents table result for 85-88, you have the text:

...Boon all 30%

Can you define boon in this context?
Customer avatar
5E Solo G February 27, 2020 11:20 pm UTC
What that refers to is that the chance of a random boon, or anything preceding it (there are other elements that may be present) is 30%. So, make a percentile (d100) roll for each of those elements, boon included. If you roll 30 or under for any of those elements, then that element is present!
Customer avatar
Jeff S February 27, 2020 11:42 pm UTC
Thanks. Apologies for not being clearer. I meant what boons? Is there a table of them I haven't found? Checking the DMG I can only find Boons for post L20 which I assume isn't the intention here.

I've posted this in another section as well, but I'm looking for some help getting started, from the very beginning Character Creation to starting first adventure and so on.
I haven't played in over 30 years and this idea of solo adventuring and rekindling old D&D caught my attention.
It seems like a lot of material to choose.
Would the Toolbox Solo Adventure A1: The Dead Don't Sleep be a good place to start or just an adventure. Or the Toolbox itself? I might like Solo, guided story perhaps more, not sure
I am starting from scratch and I'm looking for some recommendations on where I should began and what I will need for that, and perhaps to continue. But, let's just start with how I can get started for now

5E Solo G February 24, 2020 6:34 pm UTC
Hi Mark
As a starting point, I'd probably recommend my solo adventure "The Death Knight's Squire" as a primer. Then you could move onto this product from that point.
Customer avatar
Mark H February 24, 2020 6:47 pm UTC
Great, I'll check it out.
Is that the only thing I will need?
Customer avatar
Mark H February 24, 2020 6:51 pm UTC
Scratch that, I read the details of that adventure and it's all right there.
Thanks again.

No problem! I'm about to complete Book number 5 in that series.

Mark H February 25, 2020 7:16 pm UTC
Look forward to it. I ran through this last night and this morning. I enjoyed it, but made too many good guesses I suppose, because I got to the final fight fairly quick, nearly without incident. Thankfully I can do it again. I did have to re-run some combat, since being away for so long I rolled incorrectly on some of my combat, then realized why I was getting beat down so badly. Even on doing correctly, I barley survived it. Lots of fun! I'll be doing this sure, nice work and the detail is amazing!

Wanted to leave a 5 star review, but don't have the option for some reason. Thank you for these Solo Adventures. My 11yo son has just become interested in playing (FINALLY) and it makes it easier for just him and I to sit down and play together anytime during a busy week! Also purchased Solo: Dead Don't Sleep and the Solo Bundle 1. So thanks again :)

Great resource.

Basic flow charts to help players understand the order of operations for the different processes

Tables in a separate file for quick reference. For example a page of tables for travel, pages with dungeon tables, etc. Unfortunately the tables in the PDF do not lend themselves to copy paste :(

Hello! Congratulations for the big job you have done!
I have a question for the 2PC conversion table: how can I adapt it for 4PCs?
Customer avatar
5E Solo G November 17, 2019 8:53 pm UTC
Hi Simone. What you'll have to do is get hold of the Dungeon Master's Guide and turn to page 82. On there is the method for building encounters, and over on p.83 is the subheading "Party Size" which is the direction I use in building encounters for solo PCs, or small parties of 2 PCs. Takes a little mathematics, but its pretty simple really once you get the hang of it. There are also quite a few encounter building tools on the net that you can take advantage of, like the one on donjon's page, and the dhmstark page.

How do I know when the quest is complete? Assume on room contents table when you roll 93-100 for the boss? Thanks!!
Customer avatar
5E Solo G April 16, 2019 1:01 am UTC
Yeah either that, or when you feel the conditions of the quest have been met. Not every quest will end in a boss. All depends on what you created during the Quest Generation phase! Thanks Mark

Thanks! Nice book. I’ve been looking for something like this for a while now... so I appreciate putting this book together.

Is this a document that we have permission to print for home use? I want to send it to a local print shop and I suspect they might refuse to print it without author permission (due to copyright laws).
Customer avatar
5E Solo G April 08, 2019 8:36 pm UTC
You have my absolute and unequivocal permission to print this out for home use James!

Do you plan on adding tables for higher level characters? I would like to see encounter level 20/epic boon level if possible.

Rules Edition(s)
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.
