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.

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?

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

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).

Can you use this with an OSR system like labyrinth lord? I'm old school...

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

Started a Solo Session for fun last weekend, when I was at my parent's place for christmas and really enjoyed it.
I used the rules and most of the tables in the book and added some tables I had previously found on the internet and used for my regular games.

I started a Roll20 game, created two characters and started writing the story as it unfolded in a handout, using the GM-Notes section to document actions (rulewise), rolls, npc names and quirks and table results and used those details to write the story as it unfolded for my characters in the regular description section.
I started around 9 pm and before I knew it it was 3 am...

Only thing missing for me was a table index in the back of the book, since especially in the beginning, jumping to the table of contents, going to the first page of a chapter and then scrolling down several pages to find the right table can break the immersion quite a bit. Links inside the pdf might improve the navigation as well.

Ok, I just found the interactive table of contents... So I take back my point of criticism and blame it on my own ignorance ;)

Would this work with published adventures?
Customer avatar
5E Solo G December 16, 2018 5:33 am UTC
I know of at least one player who uses the Toolbox with published adventures. I think it would be good for adding extra detail to an adventure, and the question/answer mechanic could be used for determining how NPCs and monsters (and locations too) behave. So in short, yes, I think it would.
Customer avatar
Logan B September 07, 2019 6:29 am UTC
Would it work for coverting published adventures into solo adventures?
Customer avatar
5E Solo G September 07, 2019 7:39 am UTC
That's not really what its designed for. It can add extra detail to those adventures though. For converting published adventures, I'd suggest a product called Elminster's Guide to Solo Adventuring.

HVMP, Arjen S November 16, 2018 4:30 pm UTC
As a DM this product can help to take hurdles in prepping an adventure. But it is even more interesting for trying out solo play. I like it so much that I'm currently wrapping building a dedicated privately hosted web application using these rules and tables, which takes care of all dicerolling while venturing into the unknown. Recommended supplement for sure:)

5E Solo G November 19, 2018 11:54 pm UTC
Thanks for the support Arjen! Wow the website will definitely streamline things no doubt.

Is it required to have any of the handbooks to use this product? I currently only have the player's handbook.

5E Solo G November 11, 2018 7:13 am UTC
Nope, you'll be fine with just the PHB. Monster stats you can find on D&D Beyond

Sat down with this on an evening to myself and once I got the hang of it, wow - it all just flowed together. There a few typos that I'll hopefully catalogue later, but for now - any recommendations of other content on dmsguild that synchronize well with this toolbox?
Customer avatar
5E Solo G November 11, 2018 1:44 am UTC
Hi Ian! Thanks for that, glad you're enjoying it. In terms of other material, one book I quite enjoy using is the Tome of Adventure Design, which is full of all sorts of tables. Great resource for DMs but can be used for soloing too. Available on DriveThruRPG.

Would this work for three PCs to sit down and play without a DM? I always DM and would love the chance to play with my buddies.
Customer avatar
5E Solo G October 22, 2018 8:14 pm UTC
Hi Eric
Absolutely it would work, for any number of PCs. The only thing you'll need to calculate is the XP thresholds for your party so you can generate monster encounters. Check out p.82 of the DMG for guidance on how to do this. Alternately, you could use a site like donjon to generate your encounters. But everything else can be generated by the Toolbox.

This is an awesome book. I just printed it off and put it all in a binder for use at the table. I've been looking for something like this since I got into D&D and realized how hard and inconvenient it is to put together a group. Now I can play when I want, on my own terms, at my own pace. You are a godsend.

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.
