AI DM for Beginners: Your First Solo D&D Session

You've decided to try D&D with an AI Dungeon Master. Great choice. Here's what your first session will look like.

Before Your First Session

• Create a character. The character creation wizard in The Endlessness walks you through it. 5-10 minutes. See our character creation guide.
• Pick a campaign. Pre-built or sandbox. For beginners: pre-built (The Shattered Crown). See our how to pick a campaign guide.
• Have 30-60 minutes. First sessions are usually a bit longer than regular sessions because you're learning.

What Happens First

The AI starts by narrating an opening scene. You're somewhere specific. Something is happening. You have a sense of what's around you.

Example:

"You arrive in Millhaven just before sunset. The village is quieter than you'd expect. Locals give you strange looks and hurry indoors. A worn sign points to The Hollow Stag tavern. Smoke rises from the chimney."

Your job: decide what to do.

Describing Your Actions

Don't overthink. Say what your character does in normal English.

Good examples:

• "I enter the tavern."
• "I ask the nearest villager what's happening."
• "I draw my sword and check the rooftops."
• "I cast Detect Magic."

Bad examples (too complex for first session):

• "I make a Perception check with advantage to identify anomalous magical auras." (Let the AI call for rolls.)
• "I'd like to initiate a structured social encounter." (Just say what you want to say or do.)

Keep it conversational.

When the AI Asks You to Roll

The AI will call for rolls when needed:

"Make a Wisdom (Perception) check to see if you notice anything unusual."

Your character sheet's stats and modifiers are already in the system. The AI rolls for you. You see the result:

"You rolled 14. Plus your Wisdom modifier of +2. Total 16. You notice a small figure watching you from behind a stack of barrels."

Simple. The AI does the math.

Combat in Your First Session

If combat starts, don't panic. The AI walks you through it:

1. Initiative. "Everyone rolls d20 + Dex modifier. Your initiative: 15. The goblin: 11. You go first."
2. Your turn. "Your options: attack, cast a spell, use an item, or something else. What do you do?"
3. You choose. "I attack the goblin with my sword."
4. Roll resolution. "You rolled 18. Plus your attack bonus: 22. That hits. Roll damage. 1d8 + 3 = 9 slashing damage."
5. Narration. "Your blade connects with a solid thunk. The goblin staggers but stays up."

The AI handles everything. You describe actions. It rolls and narrates.

For more on combat, see our D&D 5e combat rules.

Roleplay in Your First Session

When NPCs talk, respond:

• Type what your character says: "I'm looking for information about the crown fragments."
• Or describe the action: "I ask about the fragments in a careful tone."

Both work. The AI responds as the NPC would.

Common Beginner Mistakes

• Trying to know every rule before starting. You don't. The AI will tell you when you need to know something.
• Reading ahead. Don't. The story reveals itself. Enjoy the discovery.
• Hyper-optimizing. Don't worry about the "best" build yet. Play first. Optimize later.
• Panicking in combat. Combat in 5e is deliberate. You have time to think. The AI waits.

Save Often

The Endlessness saves automatically after every action. You can close the game and resume later. No manual saves needed.

What to Expect After Session 1

You'll have:

• Explored a location.
• Met 1-3 NPCs.
• Had a combat encounter.
• Made 2-3 significant choices.
• Gained some loot or information.

This is a productive session 1.

Session 2 builds on it. The NPCs remember you. The world remembers your choices.

In The Endlessness

The Endlessness is designed for beginners. The character wizard, rules enforcement, and patient AI make learning D&D via AI easier than learning from books.

For more, see our getting started guide, character creation guide, and combat rules.

Final Takeaway

Your first session is the hardest. The second is easier. By session 5, you're fluent.
