Marginal Errors is a recipe and ritual based magic system that takes the form of an in game object the players could discover in their fantasy RPG world.

A retro inspired, rather worn, magical textbook by the well respected professor of alchemical studies Herbert Bogg.  A collection of over 120 spell and potion recipes that players can recreate in their games if they gather the, often rare and dangerous, ingredients. 

This particular copy however is scrawled and edited with annotations in the margins and throughout, tweaking and modifying the recipes to produce varied and random results. 

If players choose to follow these annotations they roll on random tables to reveal the results. 

This is a fantasy setting object but has been designed to work with any system the GM is running. 

I’ve included some test screenshots of a few of the pages to give a flavour of what the book will be about and I am hoping to fund the project through a kickstarter a little later in the year.

If this might be something you would be interested in leave a comment below, id love to get some feedback on what people think of the project so far.
