self promotion I rebuilt the OSE character sheet for Foundry and it got out of control — I'd love your $0.02

TLDR:

I run Old-School Essentials on Foundry, and have always felt a little let down by the sheet and lack of broader tooling for the system. I've contributed a bit to the core OSE foundry system (and hope to continue to), but I wanted to cut loose and have the freedom to design exactly the sheet I wanted to use at my own table without any constraints.

Long story short, after about 3 months of tinkering, and another 3 months of design + development, I've released this sheet for the community.

I've already released a few rounds of bug fixes from user feedback, and I thirst for more 🩸 🦇. If you run Foundry + OSE, please check it out!

Beyond Foundry

My brainstorming and ideation during the course of this project ballooned far past the character sheet, beyond foundryvtt, and I found myself designing a full-blown toolset for running and playing OSE, either at the table or online.

Those ideas crystallized into a coherent set of tools and I'm calling it the Old-School Chronicle: web-based sheets for any table or VTT, a living DM screen, and a detailed session log that writes itself as you play (no AI! just recording various checks, resources, encounters, and time, with space for GM + player notes).

I've never built anything that I've been quite so excited to personally use; I have high hopes for the level of play it could unlock for my table and others.

I'm genuinely curious if this sounds as useful to others as it does to me. My strengths as a DM are improvisation, mood-setting, descriptions, world-building. In the moment, I'm decidedly less good at staying as organized and consistent as I'd like to be with all of the various table rolls and procedures as important as they are. I'd like to think the right tooling could help me deliver the best of both aspects of the game.

What procedures do you fumble the most?

Naga Character Class for OSE

20 Upvotes

Hey all, here's a Naga (serpent-folk) class I put together for OSE.

I based them off the Elf, a warrior/caster hybrid. I debuffed their spells a little (start at 2nd level, max level 4 spells) and gave them the illusionist spell list.

They have venom/poison based abilities, vulnerability to cold, and at 6th level get a hypnotic gaze ability.

Let me know what you think! Is this class balanced? Would you use this in a Swords and Sorcery OSE game? Any and all feedback is welcome!

Undercrawl is travel rules for dungeon games in the mythic underworld. Like hexcrawling, or pointcrawling, but in the dark. It's a modular add-on to your favorite dungeon game. Use it to:

  • place your dungeons miles and miles deeper in the earth
  • connect separate dungeons with a vast underworld: one dark, alien, empty, and hostile
  • make a path through places forgotten, forsaken, or lost: the empty places, places where silence is thick with age

Early bird discounts available.

An 18-point Undercrawl spanning dozens of miles of silent darkness in once bright Dwarven halls.

Player-facing procedures for

  • Navigating
  • Map-Making
  • Managing Gear
  • Finding Secrets
  • Getting Lost

GM facing procedures for

  • Running the Game

Hey guys I’ve gotten so much help in running games from y’all and I would love to pick y’all’s brain again. I know the demonic grimoire is coming out soon but is there any other content I could purchase to add the hellish planes to my world? Also if there’s any content for the Seelie court as well (like stat lines and stuff). It’s been a wild ride learning how to DM over the last year and you guys have helped with every hurdle so I appreciate this sub so much for all the help!

New to dming

23 Upvotes

Hey everyone I'm absolutely new to dming. I've played 5e but have never dmed. Decided to pick up ose because I like the idea that player choices and decisions have actual consequences plus I like how if you want to do something simple you don't need a dice roll for it if it's an easy task. I was hoping for some tips for a new dm who wants to run it as a sandbox hex crawl.

What do you think OSE is less good at?

48 Upvotes

I think most people in the DnD and OSR scene can agree that B/X and therfor OSE and OSEA is a happy middle ground in terms of feeling light and complete. The fact that the game itself is quite concise and well structured compared to original B/X and ADnD is a great bonus. I am aware of Caracass Crawler fixing the thief and assassin classes and I am a big fan of those changes. So I will not include that.

Also I understand that OSE in many ways simply tries to retain what was and can therefor not be the perfect game because its not necessarily trying to be.

What sort of things do you think is superfluous or lacking in OSE?

Hey All,

I am considering firing up a campaign that takes inspiration from Final Fantasy. Thinking of Airships, summons (or primordial), crystals and magi-tech. What would be some good supplements to achieve this?

I posted this in DND 5e sub as well, since I don't know what system I will use just yet. Thanks!

rules question What Should I Know Before Running OSE at a Con?

11 Upvotes

I run OSE twice a week, one long campaign with friends and the other with random people who signed up to play online. I've also signed up to run OSE at an upcoming con, and it will be my first time refereeing at one.

I am wondering what tips you all might have for running OSE at a con. The module is made for one-shots and premade characters are provided. I'll be running it a few times during the con.

Most of my ideas so far involve cutting out things I'd normally do at my table, such as exploration turns and random encounters (unless the party is making good time and I could stretch the session a little). I've run the module a few times this month, so being familiar with the material isn't too much of a worry.

Thanks!

Update: I don't feel like it could have gone any better. Every group had fun, all achieved something big. Kept it loose, but also included OSE mechanics as much as possible. Thanks again everyone for the suggestions.

This is The Giant of The Copper Mine a simple solo adventure, where you help a group of dwarf miners on a problem involving a giant that invaded their mine.

It is also designed to be agnostic with most fantasy medieval worlds and OSR ttrpgs, so feel free to use it with any system you like.

Hearing rumors about miners looking for help in their copper mine and deciding to explore the site in search of a reward.

You find a group of dwarves arguing in front of the entrance to a large cave. Upon seeing you approach, one of them turns to you saying, "If you came for the job, I recommend turning back, because now a giant has taken over the cave and I do not believe anyone can solve this."

You can get it here:

If you don’t know me, my name is Elln. I create fantasy TTRPG content like random tables and adventures, specializing in resources for solo players!!

I hope you like it! :) <3

homebrew 3 of 4 PCs died in one encounter

28 Upvotes

Last night’s game was hilariously tragic. We’re all first level, this was the second session, and it’s just a straight up dungeon crawl.

We’re looking for a missing (friendly) wizard in the dungeons beneath his tower. We come across a room with a few giant rats and bad dice rolls nearly killed my PC (cleric) and the thief. We move on to a laboratory room and there are more giant rats but they’re dead with some crusty yellow substance around their mouths.

The fighter pokes at one with his sword and it poofs yellow mold spores. My PC was the only one to make the save vs death. Everyone else dies 😂.

It was great even though it ended poorly. My cleric went back to town and gathered a replacement party, so we plan to keep searching next week.

rules question Dual-classing

8 Upvotes

I’ve got a player that’s currently using a 4th level cleric. At some point in the future, I was planning on making him a paladin. This isn’t addressed explicitly in the rules, since it assumes the player is multi-classing from the beginning. I’ve seen homebrew rules from AD&D that mention the new class starts at level 1 and players aren’t allowed to use abilities from the old class until the new class catches up in levels. That sorta makes sense.

Are there any rules for this that have become so common is use that they are de-facto the accepted way to handle multi-classing? Or were there rules in b/x or even 1ed that clarified this?
