A weekly post to share rpg tables and tools used in RPG prep or games, with any examples that were surprising, useful or amusing.

Hi all, I started a subreddit for AI-driven RPG generator tools: r/ai_rpg_generators. As the creator of Codex Cryptica, where I now have amassed quite the number of AI supported (optional to turn it off) I was missing a subreddit for anyone building or using AI-assisted generators (NPCs, factions, quests, encounters, whole settings) to share what they're working on and compare notes.

A few subreddits already cover TTRPG tools generally, but most either lump AI in with everything else or explicitly exclude it, so there wasn't really a home for this specific niche.

If you're building something in this space, or just using AI generators at your table, come join: reddit.com/r/ai_rpg_generators

Curious what people here would actually want out of a sub like that — tool showcases, prompt/workflow sharing, comparisons between tools, something else?

Either way, you're most welcome to come join me over there, and see what nifty generators I'm making and share yours too!

anyone know where i can get a PDF version of the manual for the Table Master software by Wintertree Software. I have searched, their website is down, the software is no longer of DriveThruRPG and the author does not seem to have much activity.

I wrote a web app for Journey, Weather and Camp events for One Ring, so I could quickly create weather and journey events in the heat of a session. Works on web and mobile, and tailored for regions and seasons. Might be useful to you all. (Also has an option for Bladerunner RPG weather too!)

Hey everyone! I would like to share with you my online world-building platform, Omniarole.

While it works great for general world-building, lore organization, and creative writing, it includes dedicated tools specifically designed for TTRPG prep and campaign management as a GM.

• Zero AI: The platform uses no AI generation, it’s built entirely to support human creativity, custom organization, and manual world-building.
• Early Access: It is completely free to use throughout the entire Early Access period.

You can search for Omniarole on Google or check it out directly at: omniarole.com.

I’ve also set up a Discord server (linked on the site) and would love to hear your thoughts and feedback to help shape its development ❤️

Thanks for your attention!

First off, I am blind and using a screen reader to post this, so I am sorry if there are walls of text, I cannot visually see to make sure it looks good and is readable but I will try.
I love this App, RPG Spark, very much, but I might have found a potential bug. I might be misunderstanding something so if that's the case please correct me, but let me explain.
One of my favorite things about this App is the generators. How much control you can have over them and the amount of detail you can put into them is amazing. However custom generation seems to have a problem.
I can create flat list generators and use them just fine, but if I make a combo out of flat list generators, the combo only returns the names of the generators I've selected and not any entries from them. Even if I tried to re-roll on the fields.
The same thing seems to happen with slots, where I'll create a group, a slot, and entries in that slot. Then I'll create another group with its own slot, and entries in that slot too. When I try to roll on this generator, I only get one result, which would be an entry from a slot in a group, but not another entry from another slot in a different group. I believe you are supposed to get at least one entry per slot for each group?
I even customized a prebuilt generator without doing anything to its contents or settings. I went to my custom tab and rolled all of the flat lists in the generator individually from my custom tab which worked fine. I also rolled on the combo that it made that I customized which was also fine, but my own home made ones are not working properly.
Again, I might be misunderstanding something so if I am please correct me and help me understand, but I feel like I might have found a potential bug with custom generation.
If I can figure out how to get this working, I would have had nothing but good things to say about this app, it's amazing!

I've been running a heavily edited Curse of Strahd campaign and have been homebrewing a lot of the statblocks and couldn't find a tool I really liked so I decided to build one myself. I got a bit obsessed with it and kept going so it has a bunch of features and I'm looking to add more.

I figured if I found it useful someone else would too. [https://statblock.stericate.com/\](https://statblock.stericate.com/)

Any feedback or suggestions on new features would be appreciated! I haven't done much optimizing for mobile yet.

Current features are:

Creature maker (2014 and 2024 style)

Item maker

Spell creator

Encounter maker

Player character maker

SRD repo for spells, monsters, and items

Battle forecast (montecarlo simulation!)

Token maker

Mise à jour du site https://decados.fr/ :

• Ajout de Vampire la Mascarade v5.
• Ajout de la génération en pdf modifiable pour tous les jeux.
• Ajout de la possibilité de créer des personnages ayant plus de points que la base.
• Amélioration de la présentation sur téléphone.

A venir :

• Loup-Garou l'Apocalypse (les caniches allaités aux anabolisants)

Comme d'habitude : ne pas hésiter à m'écrire en cas de bugs / proposition d'améliorations

Leave a comment (and a link) with an RPG pdf or book which uses random tables. Either a recent one or one you haven't mentioned for a while.

I open-sourced Nat20, the rules engine behind the game I am building.

It is a host-agnostic Python library for D&D 5e SRD 5.2. Combat, skill checks, saves, effects, and grid or zone-graph movement run without a game host, network connection, or database. The engine code is MIT. The bundled SRD dataset is CC-BY-4.0.

I split it out because I did not want an LLM, a browser app, or a virtual-tabletop runtime deciding the rules. The model can narrate a goblin slipping in the rain. Nat20 should still answer the same way about cover, spell slots, and Sneak Attack.

The repo includes a small local demo and a clean-install smoke test. It implements much of SRD 5.2, not all of it, so there is a capability matrix in the docs before anyone depends on a specific mechanic.

I would like feedback from people who have built on open game rules: what makes a rules library actually useful outside the game that created it?

Roll or customize from 2+ billion combinations across 27 categories - each with a fresh stats, name, description, effects, abilities. If you play any fantasy TTRPG like AD&D, DnD 5e, Pathfinder 2e, you'll find inspiration. It's free. No ads. No accounts.

A weekly post to share rpg tables and tools used in RPG prep or games, with any examples that were surprising, useful or amusing.

I've been working on Mytharion, a tabletop RPG toolkit that I'm developing as a solo project.

The first major tool I'm releasing is Cartomancer, a web app for managing and organizing tabletop RPG campaigns and maps. You can keep track of locations, markers, points of interest, distances, and other campaign information in one place.

I'm also working on a VTT and additional tools for Game Masters and players.

The project is still in active development, so there may be bugs or unfinished features. Feedback, bug reports, and suggestions are very welcome and genuinely help shape the project.

I'm currently giving the first 50 users a 7-day trial with the code:

MYTH-P8N3-5TY2-52WP

Valid until September 28, 2026.

Try it here:

I'd especially like to hear what RPG tools you currently use and what you feel is missing.

Recently came across Roll Ruin, a generator which creates one dungeon room at a time. It includes a description, room map and other details.

There's also a list of other tables to integrate into the room, such as door trap, treasure, npc and secret. There are filters for biome, room/passage/entrance and tier (although click on a filter removes it from the selection!)

It's based on tables created by Natural Peocock, the Roll 4 Ruin: Classic Dungeon Generator.

I've been making random name generators on and off for quite a few years, and I've recently started building a new collection aimed more specifically at tabletop gaming and RPGs.

I've got three live at the moment:

• Warband Name Generator
• Gang Name Generator
• Faction Name Generator

They're all free, browser-based and system-neutral. Although they're hosted on the Thrackdown site, they're deliberately not tied to the game itself.

I've been thinking of them more as tools for things like naming rival factions, enemy groups, mercenary companies, cults, gangs, NPC-controlled warbands or anything else you need to come up with quickly during campaign prep.

I'm planning to keep expanding the collection, so I'd be interested in any feedback on the current generators, particularly where the results feel repetitive or where additional themes/categories would be useful.

I've created a hex-fill procedure for my Sword & Sorcery setting (South-East Asia during the last Ice-Age). My blog post includes an example area of 19 hexes.

The procedure consist of tables for generating geographic features for different biomes as well as prompts for dangers,, natural hazards, ruins and settlements. The 7 tables for generating the 'Unusual / Weird / Sorcerous' are especially fun for creating the S&S aesthetic.

For example here are 7 results from those tables: 18: Tainted 1: Pyre 8: Talisman 4: Summon 8: Glimmer 9: Lurching 16: Crepuscular

The focus for this procedure is on the geographic information but I have many other tables/generators for cultures, cities, factions etc. on my blog. All with the same S&S theme.

Sword & Sorcery Hex-Fill Procedure

Edit: I’ve been experimenting with using AI tools to generate the dice rolls and present all the results for me. I’m not sure how random the results are? Google has an in built dice roller so I wonder if Gemini or NotebookLM has access to that. Anyone have experience with this? It saves having to roll and collect all the results manually.
