Build a one-shot with your team. Watch a table play it.
Three friends, one booth, 60–90 minutes. You plan on the whiteboard and talk it through. The AI types it up, you edit, and you walk out with a playable Pathfinder 2e or D&D 5e adventure in Foundry VTT. Later, another group sits down and plays it.
“Fill your con haul with great stuff from the hall, and add one thing you made with your team.”

AMBA · Room 5
No typing
The AI does the writing. You prompt, then you edit.
Plan on the whiteboard
Sketch every room with your team first, so you need fewer prompts.
Fewer prompts can win
Prompt count is tracked, and fewest prompts is an award category.
Leave with a one-shot
A playable Foundry module your team made, and a table of strangers playing it.
From map card to played adventure
Every round closes the loop: build, export, and play, all at the same event.
Pick a map
Draw three partner map cards and pick one. Walls, doors, and lighting are already done.
Whiteboard it
Decide every room, the boss fight, the ending, and your player handouts.
Talk it into AMBA
The narrator speaks, the AI writes it up, and the editor fixes by hand. Pre-gens are built alongside.
Ship to Foundry
One export through the AMBA–Foundry bridge into the ready scene, with pre-gens loaded.
A table plays it
Another group plays it later. The GM pushes your handouts to their phones.
The AI is the typist, not the author.
In One-Shot Forge, the AI only writes up and expands what your team tells it. It never suggests plot, monsters, names, or mechanics. Ask it for ideas and it hands the question back to you.
- No AI art. Maps and art come from partner vendors or the public domain.
- The rules are disclosed at sign-up and posted in the booth.
- The skill being tested is the one every GM uses: planning well and directing clearly.
What the AI will and won't do
Will
- Write up the room you described
- Format stat blocks, DCs, and traps you named
- Read back and check your work
- List every monster you used
Won't
- Invent a plot or a twist
- Pick monsters or names for you
- “Write the whole adventure”
- Generate images
Any convention, game store, or club can run it.
One-Shot Forge isn't tied to one show. Organizers run it themselves with a booth, a whiteboard, a big monitor, and the kit. It runs on cloud servers by default, or on your own on-site servers if you prefer.
Cloud by default
No servers to buy or babysit. Bring the booth, the screens, and a solid internet connection.
Self-host if you want
Run AMBA, Wanderer's Guide, and Foundry on a Linux/Docker box on your own LAN, so venue Wi-Fi carries only light AI text traffic.
No player AI accounts
Organizers get an Unwhelm API key for the event's own AI client, so teams don't need a subscription of their own.
Unwhelm doesn't need to be on site for you to run it. The AMBA source is available on request for organizers who want to host everything themselves.
Good for everyone at the con
For attendees
- Something they made, not something they bought
- A social, team-first event with small private groups
- Writers watch strangers play their adventure
For organizers
- A new two-part event: build tickets and play tickets
- Portable: a meeting room or the exhibit floor
- Every finished module feeds the play schedule
For vendors
- Partner maps, art, and minis used and credited in every module
- Play tables send players to the hall
- Additive to the hall, never a substitute for it
Bring One-Shot Forge to your table.
Convention organizers, game stores, clubs, and partners: we'd love to show you a live round.
