General Purpose Sourcebooks

Title Description Version
Directive Deck A guide for generating vague, possibly conflicting orders from a detached organization. Uses a deck of 52 playing cards, and lots of imagination. v1.1
Adventure Scene Tables This was originally some random tables for minor things that could happen in a fantasy setting. I think I originally made this as part of some community project. As of the 1.2 update, I've added several new tables, and expanded the types of tables. Thus, Fantasy was dropped from the title. v1.2
Sneaking and Stealing Stealth Missions (I hate that term) failing because one person gets a bad roll? Try taking this sub-system for whirl! v1.0
Information and Investigation Wizards spend all their time in their towers researching magic, but there's a startling lack of sub-systems covering how to do that. So I made one myself. v1.0
The Leyak When I found this thing in the game Abiotic Factor, I thought "This is one of the most evil things you can put into a game." So naturally, I cooked up something for putting it into a ttRPG. v1.1
Updated! Shapes and Abstracts I originally titled this "Scales." When writing Tabletop Alchemy, I found myself wanting a sheet that I could fill out to explain how elements in a fantasy game would interact. After I was done with that, I thought it fit in well enough with Scales, since all of them were wild experiments in using shapes to represent ideas. I appended the elemental sheet, which used dodecagons, to the end of Scales and renamed it. v1.0
The Liminal Man The Liminal Man is...a Vinny Vinesauce meme. It's about a man. And this man exists in liminal spaces. So what we have here, is a ttRPG sourcebook. It describes meeting him, and what happens after. v0.2
Drama du Jour A branch of the Directives Deck, this uses a deck of cards to determine the nautre of a conflict between groups with ranks and hierarchies. v0.1
New! Three Stage Crafting One of my friends kept telling me that including crafting systems in tabletop RPGs is a path to madness. He's not wrong, but he forgets that I'm also out of my flipping mind. To that end, instead of making a specific crafting system, I came up with a framework for making crafting systems. Because that's what we need, right? A complication to a complicated idea! v1.0
New! Tabletop Alchemy I saw the Nile Red videos where he does wild stuff like turning toxic chemicals such as paint thinner or rubber gloves into soda and hot sauce, and it reminded me that chemistry really is a modern day magic. So I took some of the recurring ideas I saw in those videos, and converted them into a tabletop RPG sourcebook for things like potion making. This was also one of the first sourcebooks I specifically drew artwork for, and made two additional "helper" books to make sense of how I was trying to design this one. v1.0

Game Specific Rulebooks

Ryuutama

Title Description Version
New! Yellow Ryuujin This was one of the first sourcebooks I can recall writing: evidenced by the fact that when I found it, I didn't have the sense to include a credits page stating that it was my doing. The Yellow Ryuujin was desgined to indicate that the game was primarily about economics or treasure hunting. v1.1
New! Body Building Brothers' Bouken A scenario I wrote for Ryuutama about four BODY BUILDING BROTHERS on a journey to THE GLORIOUS GROTTO OF GAINS. As it turns out, THE GLORIOUS GROTTO OF GAINS is a gym in the mountains. This was my attempt at making a scenario that was at once meant for higher level characters, while still using pre-mades, and also as a way of codifying giving player characters private information, without the game master announcing it publicly for the entire table. v1.0
