"D&D in arcade mode!" ~ Prince of Nothing
This is my own heavily house-ruled hack of B/X and 5e, suitable for one-shots, convention games, virtual play, and even face-to-face campaigns. I'm currently 16-sessions into my Crystals of Chaos campaign set in the eldritch, gonzo, science-fantasy, post-apocalyptic world of Cha'alt. Check out my session reports on Venger's old school...

This is a different kind of Alpha Blue... for starters it's D20; it's also not quite as silly. Yeah, this version is darker and grittier than the original. Just as sleazy, though! Maybe you've played Alpha Blue before, maybe you haven't. Either way, I'd love to know what you think of this version.
I'm hoping to playtest and get feedback on Alpha... [click here for more] |

This is pure gonzo-light, science-fantasy, eldritch pulp awesomeness! O5R compatible (including Crimson Dragon Slayer) scenario pretty much requiring The Islands of Purple-Haunted Putrescence (if you don't already own it, get it - you'll thank me).
Within Battle For The Purple Islands, you'll come across cultists, cannibals, talking apes, and other... [click here for more] |

All the bloodsucking, none of the baggage!
This is a complete vampire RPG where you get to play demonic bloodsuckers stalking the night, feeding on mortals, and reveling in the dark, pre-apocalyptic cities of the modern era. Whether you're good, evil, or just out for yourself is completely up to you... but every choice has a price.
Blood Dark Thirst uses the VSd6 system,... [click here for more] |

"Like Cha’alt before it, Cha’alt: Fuchsia Malaise is a sandbox that allows the party the freedom to explore and go wherever they want. There is always something weird and unique around the corner." ~ The Mixed GM

This is a collection of my own O5R house-rules for D&D. It's a blend of both old school, 5th edition, and my own special sauce. For best results, use with my eldritch, gonzo, science-fantasy, post-apocalyptic campaign setting CHA'ALT.

I've just launched a new Kickstarter for my upcoming book, The Cha'alt Experience: Designing Worlds Like A Fucking Boss. Check it out!
[I decided to make this a freebie because A) it's incredibly important to the development of D&D's combat evolution, and B) this content is already included in Cha'alt: Chartreuse Shadows]
Long story short, this kicks ass! ... [click here for more] |

"This thing is pretty f#cking Lovecraftian!" ~ Abdul Alhazred
Dead God Excavation is a short adventure for characters between 1st and 3rd level. I happen to think it's perfect for kicking off a gonzo, eldritch, science-fantasy campaign. If you incorporate this into your "session zero"... respect, hoss!
This scenario was written for Crimson Dragon Slayer... [click here for more] |

This is neither an adventure nor campaign setting, but a place where Lovecraftian horror happens!
There's a monolith and nearby stairway down into the earth. La Bas Chartreuse contains various scenario seeds with specifics that can be used to flesh things out. You'll also find several random tables, a couple of which can be used in many, many investigative horror and eldritch... [click here for more] |

This is the latest in a long line of Cha'alt scenarios. Unlike the vast majority, this one is for higher level (4th and 5th) PCs, but like anything, it can easily be adjusted on-the-fly.
I used Midjourney A.I. to create almost every piece of artwork in this PDF.

As I did with Crimson Escalation about a year ago, I'm now making Obsidian Escalation free for every DTRPG customer, as I believe it's an important evolution in the O5R design school that seeks to elevate story and player-agency within that "storygame" sphere... without the expectant storygame garbage that usually comes with it.
Also, now's the time to grab your weekend... [click here for more] |

Like the first S'rulyan Vault, this is two extremely high-resolution dungeon maps in both old school blue/white and bloody parchment hue. The dungeon is huge and contains a variety of cavern and traditional room/corridor areas... along with special icons.

When I had the idea for a Cha'alt webcomic, I didn't know what to expect or how long such an endeavor would take.
Well, it looks fantastic and Under Fuchsia Ska'ai took 9 months to complete. Jae Tanaka's artwork on this project has unbelievable character, whimsy, action-adventure, and strangeness... just perfect for my eldritch, gonzo, science-fantasy, post-apocalypse,... [click here for more] |
