Monophobia - Rules Light Solo Roleplaying



Rules Light Solo Roleplaying


This book is designed for use with 7th Edition Call of Cthulhu but will work perfectly well with any edition if you are aware of the positive and negative dice rules and the concept of half and one-fifth values. A character's Luck, half luck, and one-fifth of their Luck attribute play a major role here.

I am fully aware that these are not the only solo rules for Call of Cthulhu in the Miskatonic Repository. This book takes a completely different approach to solo play than the Solo Investigators Handbook. That PDF is 95 pages and has tables for just about everything.

The solo rules in this booklet represent a light-touch approach to solo play. There is one table for plot hooks to kick off a solo sandbox campaign. It is a 10 x 10 x 10 table, commonly called a d1000 table, These create a who, what where plot hook to get you going.

Optional tables are provided for answering Keeper questions but when playing you will not need to refer constantly to this booklet. This is a book of techniques to drive your improvisation. If you are having a day when inspiration deserts you, then you can fall back on the tables.

There is also a section on running investigations, using either an open sandbox or a purchased campaign. A slightly different technique is used for purchased campaigns. In the sandbox no one will know, not even you will know what is really going go behind the plots and conspiracies until you discover the truth for yourself. Everything is open until the clues you have discovered point you to the truth.

To use this booklet you will need a copy of the Call of Cthulhu rules, two sets of d100 dice, and a pack of regular playing cards.




DriveThruRPG does not support Community Copies. The entire text of this supplement is viewable in the Full-size preview. If you cannot afford the cover price, please feel free to use the preview with my full blessing.

Nice Mono rules. Really good for developing and sharpening your Keeper skills. I intentionally didn't flesh out a portion of a game I ran last Thursday and used some of the tips and tricks to develop a compelling narrative of the fly. By Yog it's a worthy purchase.

Why would you use the same title as an excellent FREE collection of scenarios which has been available for a decade:

I didn't realize that existed. I did check for the title on DriveThruRPG and it had not been used.
I just had a look and although the titles are similar, they are not the same. They are also very different books, aimed at different target audiences.
There was no intention to hijack the title. I have changed mine just as an act of goodwill.

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.
