How to Plan a D&D Session 0 Step by Step
A good D&D campaign does not begin when the first goblin gets stabbed.
It begins before that.
Before the dice.
Before the tavern meeting.
Before the wizard asks whether fireball works indoors.
It begins with Session 0.
Session 0 is where the Dungeon Master and players agree on what kind of game they are about to play. Not every table needs the same kind of Session 0, but every table benefits from getting expectations out in the open before the campaign begins.
So if you're preparing your first campaign, don't just ask, “Are we ready to play?”
Ask, “Are we ready to play the same game?”
Let's plan it step by step.
Step 1: Explain What Session 0 Is
Start simple.
Tell your players that Session 0 is not a normal adventure session. It is a planning session before the campaign begins.
You are not gathering everyone to lecture them.
You are gathering everyone to agree on the shape of the campaign.
You might say:
“Before we begin the adventure, I want us to spend one session talking about the campaign, characters, expectations, rules, and anything we want to avoid. That way, everyone knows what kind of game we're playing before we start.”
That's enough.
Don't make it sound grander than it is.
Session 0 is just the table sharpening its tools before the work begins.

Step 2: Present the Campaign Pitch
Before players make characters, they need to know what kind of world they are stepping into.
Give them a short campaign pitch.
Not a novel.
Not twelve pages of kingdom history.
Just enough to answer:
What kind of adventure is this?
What tone are we aiming for?
What will the characters mostly be doing?
What kinds of characters fit this campaign?
For example:
“This campaign is a heroic fantasy adventure about a frontier town surrounded by ancient ruins. There will be exploration, dangerous monsters, lost history, and some political tension, but the tone is mostly adventurous rather than grim.”
That tells players far more than a lore dump.
Now they know whether to build a wandering knight, a treasure hunter, a scholar, or a cheerful chaos gremlin with a bag of bees.
Step 3: Agree on the Tone of the Game
Tone is one of the biggest reasons campaigns go wrong.
One player thinks the campaign is heroic fantasy.
Another thinks it is dark horror.
Another thinks it is tavern comedy.
Another thinks it is tactical war gaming with goblins.
None of these are wrong.
But they can become wrong for each other.
So ask the table:
Are we playing serious, silly, or somewhere in between?
Is character death common or rare?
Are moral choices heavy or light?
Is this campaign heroic, grim, chaotic, cozy, or dangerous?
How much comedy do we want?
This does not mean every moment must follow the same mood.
Even serious campaigns need jokes.
Even silly campaigns need consequences.
But everyone should understand the general direction.
A table that agrees on tone is far less likely to trip over itself later.
Step 4: Discuss Player Expectations
Now ask what the players actually want.
Some players want combat.
Some want roleplay.
Some want mystery.
Some want exploration.
Some want to build the strongest character possible and see what survives contact with the battlefield.
Ask questions like:
What are you most excited about?
Do you prefer combat, story, exploration, puzzles, or social scenes?
Do you like difficult tactical fights?
Do you enjoy speaking in character?
Do you want personal character arcs?
Do you prefer clear quests or open-ended freedom?
This helps you prepare the kind of game your players will actually enjoy.
It also helps players understand each other.
A quiet player who wants emotional roleplay may need a different kind of spotlight from a tactical player who loves battlefield decisions.
Both belong at the table.
But you, the Dungeon Master, need to know they are there.

Step 5: Set Table Rules and Etiquette
Every group has rules, whether they say them aloud or not.
Better to say them aloud.
Talk about:
Phones at the table.
Side conversations.
Rules arguments.
Player-versus-player conflict.
Splitting the party.
Spotlight sharing.
Attendance.
Late arrivals.
How decisions are made.
This is not about being strict for the sake of control.
It is about preventing silent resentment.
For example, if one player constantly interrupts others, that can damage the table faster than any monster.
If one player treats every disagreement as a rules debate, the game can start feeling like a courtroom with dice.
Set expectations early.
A good table does not need everyone to be perfect.
It needs everyone to understand what kind of behaviour keeps the game healthy.

Step 6: Talk About Safety and Boundaries
This part matters.
D&D can include violence, horror, betrayal, grief, romance, religion, trauma, body horror, slavery, torture, abuse, and all sorts of heavy themes.
Not every table wants all of that.
Not every player is comfortable saying so in the moment.
Session 0 gives everyone a chance to set boundaries before the game begins.
You can ask:
Are there topics we should avoid completely?
Are there topics that can exist off-screen but not be described?
Are there themes people want handled carefully?
What should players do if a scene becomes uncomfortable?
You do not need to make this dramatic.
You can keep it calm and practical.
The point is simple:
No game is worth making someone feel trapped at the table.
A strong Dungeon Master does not lose control by respecting boundaries.
He earns trust.
Step 7: Explain House Rules
If you run the game differently from the book, say so now.
Do not surprise players three sessions later.
Cover things like:
Character creation rules.
Ability score generation.
Starting level.
Starting equipment.
Allowed books.
Homebrew rules.
Critical hits.
Flanking.
Death saves.
Resurrection.
Resting rules.
Encumbrance.
Inspiration.
Multiclassing.
Feats.
You do not need to explain every rule in the game.
Just explain anything that affects player decisions.
If a player builds a character around a rule you secretly changed, that is going to cause trouble.
Better to be clear now than apologetic later.
Step 8: Build Characters Together
Session 0 is one of the best times to create characters as a group.
Not because every party needs perfect balance.
They don't.
But characters should have a reason to adventure together.
Ask each player:
Who is your character?
Why are they adventuring?
Why would they stay with this group?
What do they want?
What are they afraid of losing?
Do they already know another character?
This prevents the classic problem:
“My character would never work with these people.”
Well then, laddie, make one who would.
Characters can argue.
Characters can disagree.
Characters can even dislike each other at first.
But the players should understand that the campaign works best when the party has a reason to continue together.
For players who worry their characters are not strong enough, Characters Who Aren't Optimized But Are Unforgettable is a useful reminder.
Step 9: Decide the Party's Starting Connection
Do not rely on “you all meet in a tavern” unless you know what you are doing.
It can work.
But it often leaves players awkwardly waiting for someone else to care.
Instead, give the party a shared starting point.
Examples:
They were hired for the same job.
They survived the same disaster.
They belong to the same guild.
They owe the same person a favour.
They are travelling in the same caravan.
They are protecting the same village.
They are investigating the same threat.
This gives the first session momentum.
The players do not have to invent a reason to care.
They already have one.
Step 10: Confirm the Schedule
This is boring.
It is also vital.
Many campaigns do not die because of bad villains.
They die because nobody agreed what happens when someone misses a session.
Discuss:
How often will you play?
What day and time?
How long is each session?
What happens if one player cannot attend?
How many missing players cancels the session?
Will sessions be online, in person, or mixed?
How will the group communicate between games?
Be honest.
A monthly campaign that actually happens is better than a weekly campaign that collapses after three sessions.
Step 11: Prepare Players for Session 1
Before Session 0 ends, make sure everyone knows what happens next.
By the end of the meeting, players should know:
Their character concept.
The campaign tone.
The party's starting situation.
The basic rules of the table.
The schedule.
What they need to prepare before Session 1.
You do not need every character sheet to be perfect.
You do need everyone to know what they are walking into.
End with clarity.
A good Session 0 should make players feel more excited, not more confused.
A Simple Session 0 Agenda
If you want a clean structure, use this:
Explain what Session 0 is.
Pitch the campaign.
Agree on tone.
Discuss player expectations.
Set table etiquette.
Talk about safety and boundaries.
Explain house rules.
Build characters together.
Connect the party.
Confirm scheduling.
Prepare for Session 1.
That's enough.
You don't need to run Session 0 like a corporate meeting.
You just need to make sure the table knows what kind of adventure it is agreeing to.
Final Thoughts
Planning a D&D Session 0 is not about controlling the players.
It is about giving the campaign a strong beginning.
You are not trying to remove surprise, mystery, or chaos.
Those things belong in D&D.
What you are trying to remove is confusion.
A good Session 0 helps players understand the world, the tone, the table, each other, and the adventure ahead.
That way, when Session 1 finally begins, the party is not stumbling around wondering what game they are playing.
They are ready.
And that, laddie, is when the real trouble begins.
