Session Zero in Solo D&D: Is It Needed?

Session zero in group D&D is the pre-campaign meeting where players and DM align on:

• Campaign tone.
• Character concepts.
• House rules.
• Comfort boundaries.

In solo AI D&D, do you need one? Kind of.

What's Useful

Tone Alignment

Decide:

• Dark fantasy or heroic?
• Comedic or serious?
• Realistic or fantastical?

Write it down. Reference when the AI drifts tone.

Character Concept

Before character creation, sketch:

• Backstory.
• Motivations.
• Personality.
• Arc direction.

See our character backstory guide.

House Rules

Decide:

• Using optional flanking?
• House rules on resting?
• Critical hit house rules?

The Endlessness has settings for these.

Comfort Boundaries

Even solo, decide:

• Is mature content OK?
• Is character death acceptable?
• Are there topics to avoid?

The AI respects preferences.

What's Not Useful (Solo)

• Group coordination (no group).
• DM collaboration (AI runs itself).
• Player-player relationships.

Solo session zero is shorter than group session zero.

When to Skip

If you're:

• Playing a one-shot.
• Just testing a character.
• Not invested in a long campaign.

Skip session zero. Jump in.

When Session Zero Pays Off

• Long campaigns (20+ sessions).
• Dark fantasy campaigns where tone matters.
• Characters with complex backstories.
• Experimental builds.

A 10-minute session zero pays for itself across many sessions.
