Playtester Training
Welcome to the 20 Below Playtest
Everything a new playtester needs: what the playtest is for, how to get set up, how to play the rules as written, and how to send feedback the team can act on. Six short lessons and a final check, about 15 minutes in all.
Part 1 · Lesson 1
What a playtest is for
You're testing the game, not yourself
20 Below is in active playtest. The rules are complete, but they've only been played by so many tables. Yours will find things ours never did. There are no wrong reports: if something confused you, slowed you down or didn't feel right, that's exactly what we need to hear.
What we want to learn
Clarity
Can a table read a rule once and agree on what it means?
Speed
Does a turn, a fight or a whole session move at a good pace?
Balance
Do the numbers hold up: Gifts, Boons, adversaries, Difficulty?
Fun
Does it feel good to play? Which moments land, and which fall flat?
Tools
Do the Character Creator, Battle Tracker and Owlbear extensions help at the table, or get in the way?
If it surprised your table, it's worth a report.
What we ask
Play at least one session per round, and send a Session report after every session you play. When something specific comes up, like a rule nobody could read the same way, send it as its own report too, so it isn't lost inside the session notes.
What you get
Your name in the credits
Send at least one piece of playtest feedback and you're credited, under the name from your application, in the books and on the website.
A copy of the main book
Complete every round of the playtest and you get a copy of the main 20 Below book.
A place in the world
Complete every round, earn at least one Detailed report per round, and answer the team's follow-up questions within a week, and you will be written into Backwater Static as an NPC. Choose a Foundation agent or another character, and suggest a name and one detail. The team writes the character. Lesson 5 shows what makes a report Detailed.
What you can share
Stream it, post about it, write it up. The core rules and the Backwater Static campaign core are open under the ORC License, so anything from them is yours to share. The exception is the expansions you may see before release, the Foundation book and the full bestiary. They aren't public yet, so keep them to yourself until the team releases them.
Part 1 · Lesson 2
Getting set up
You're in: your application was approved. Everything else is free and online, and setup takes about half an hour, most of it making characters.
- Find the playtester channelOn the 20 Below Discord, the team has opened the playtester channel for you. Read the pinned post: it names the current round and its focus, and has the feedback form link.
- Read the coreStart Here walks through the core roll, Attributes and how a turn works. GMs, also read Running the Game.
- Make charactersUse the Character Creator in a browser, on a phone or on Windows. It does the math, so the table can focus on choices.
- GMs, prepare the fightBuild an encounter with the Encounter Difficulty Calculator and run it in the Battle Tracker.
- Playing online?Install the Owlbear Rodeo extensions from Downloads: a character sheet for players and a battle panel for the GM.
- Print the Quick Reference GuideEvery player reference sheet in one PDF, for the table.

Part 2 · Lesson 3
Play it as written
Play the round's focus
Playtesting runs in numbered rounds, and each round has a focus, like character creation and the core roll, or combat. Make sure your sessions include it. Everything else is still worth reporting, but the focus is where we need the most tables.
The most useful thing a playtest table can do is play the rules exactly as they're written, even where you'd normally house-rule. A house rule hides the problem we need to see.
Notes worth taking
Note the round or scene, so you can find it later.
When a rule causes trouble, write down where it is and what it says.
How long did character creation, a combat round or the whole fight take?
Confusion, groans, cheers. Reactions tell us as much as numbers.
If the table had to pick a reading to keep going, write down which one.
When the table can't agree
Pick the reading that seems closest to the text, note it, and keep playing. Don't stop the session to settle it. Send it afterwards as an Unclear rule.

Part 2 · Lesson 4
Bug, feedback or question?
Three doors
Three kinds of "this isn't right", and each has its own door. A crash or a broken button goes to Report a bug, at the bottom of every page and in every tool. Something about how the game plays goes to the playtest form. A question goes to the 20 Below Discord.
Where does it go?
The Battle Tracker froze when we added a sixth creature.
Everyone sprinted every round because it was cheap.
Can a Gift and a Boon stack?
The Save button on the Owlbear sheet does nothing.
Character creation took the whole first session.
Where do I find the Difficulty chart?
Part 3 · Lesson 5
The playtest form
Open the form from the link pinned in the playtester channel. It takes about five minutes.
- What kind of feedback?Unclear rule, Too slow, Balance, Not fun, Tool issue, or Session report for notes on a whole session.
- One-line summarySpecific enough to tell it apart from other reports: "Sprint costs too little Ki", not "Movement".
- Which rule or tool?Pick it from the list, so it reaches the right person.
- What happened at the tableWhat you were trying to do, what happened, and how the table reacted. Numbers help.
- What would have worked betterOptional, and welcome. You don't need a fix to send a report.
- About the session, and your nameDate, number of players, GM or player, and your Discord handle so we can reply in the thread. Then send it, and note your P# ticket number.
What makes a report Detailed
At triage, the team adds the Detailed tag to any report that does all five of these. Detailed reports count toward the NPC reward.
- Names the rule or tool
- Describes what happened, in order
- Gives numbers: time taken, rolls, rounds or players
- Says how the table reacted
- Suggests what would have worked better

A Detailed report
Balance · Sprint costs too little Ki.
Rule: Movement, Sprint. From round 2 on, all four characters sprinted every round, so nobody ever walked; the fight took 9 rounds and about 50 minutes. By round 4 the players were joking that walking was for NPCs. Maybe Sprint should cost 2 Ki, so it's a choice? Played Oct 3, four players, I was GM.

What happens next
Your ticket's tags
Every report becomes a P# ticket in the #playtest-feedback forum. Its tags tell you where it stands.
New
It's arrived. Every ticket gets a first look and a reply within 48 hours.
Discussing
The team is talking it over. Watch the thread; they may ask you a question.
Changed
A rule or tool was updated because of your report. The thread says what changed.
Won't change
The team considered it and kept things as they are, and the thread says why.
Detailed
Your report did all five things a Detailed report does. It counts toward the NPC reward, whatever the team decides about the rule.
When a round ends
The team posts what changed and why, in the playtester channel, the newsletter and on the News page. Your reports are part of that. Then the next round opens with a new focus.
Every report gets read, and every report gets a reply.
