Unlocking the Power of AI in Solo D&D

What is Solo Role-Playing with ChatGPT?

Solo role-playing, as the name suggests, involves playing a role-playing Game entirely by yourself. Traditionally, Dungeons & Dragons requires a group of players and a Dungeon Master (DM) to guide the story. However, solo play allows you to experience D&D's narrative and strategic elements without needing a group. ChatGPT steps in as your AI Dungeon Master, providing descriptions, managing NPCs, and adjudicating rules.

With the advent of Large Language Models, the possibilities for single-player tabletop games have opened up more than ever. The key is the use of chatbot programs like ChatGPT. The video’s creator is on his third iteration of using ChatGPT as a solo Dungeon Master, so that he can explore his personal adventures, while it automates a lot of the manual game administration he would otherwise need to do.

The Experiment: Turning ChatGPT into a Dungeon Master

The challenge lies in effectively communicating your intentions and the rules of D&D to the AI. It's all about crafting the right prompts. Early attempts may result in the AI overstepping its bounds, revealing information your character wouldn't know or even controlling your character's actions. However, with careful prompting and iterative refinement, you can train ChatGPT to be a reliable and creative DM assistant.

The content creator in this video states that the goal is to discover how to use ChatGPT as a DM. ChatGPT is a language model. It creates stories and text. But how well can it act as a DM and make decisions, while still allowing the human to have agency? How much DM-ing can ChatGPT handle, so the human can enjoy gameplay?

Image Generation to Add Value

Setting a Scene

You can use a prompt in ChatGPT to create an image Prompt. Then enter it into an image generator, like Midjourney. This method can be used to set the tone of the D&D gameplay. It also makes ChatGPT more useful. If an AI Dungeon Master can create the scene, it is even more useful.

The content creator shows an example of a tavern scene in his campaign, which ChatGPT rendered. This image was entered into Midjourney. This image becomes a visual aid to help you decide what your player is doing and feeling.

Crafting Effective Prompts for a Chat-Based Dungeon Master

Specific Prompts

The most important aspect of this process is writing your prompts and being as specific as possible. Here are some instructions:

  • Limit the All-Knowing DM: The AI will attempt to reveal all, but in a true game, you learn as you go. Do not give your DM free license to tell you everything your character doesn’t yet know. The AI may begin the scene telling you there are two goblins waiting to ambush you, but you wouldn’t know that!

  • Maintain Character Agency: AI dungeon masters must understand the need to offer only the information that the character should know. The language model will begin role-playing as your player character, and decide what actions to take on your character’s behalf. It is important that it refrains from this.

  • Tell it to Take Initiative: To be a proper dungeon master, the system will have to take the initiative to move the plot along with action, conflict and making decisions to have actions.

Writing a More Powerful Prompt

According to the creator, his third session using ChatGPT was built on previous prompts and corrections he made to the chatbot. You can review these and more prompts at the content creator’s website.

You can also see, in the text itself, where these instructions for ChatGPT prompts can be seen:

  • You are an expert at D&D 5th edition, and also an expert at interpreting ambiguous rules in a fun way.
  • Rely on the Dungeons and Dragons 5th edition rules from sources like The Player's Handbook, The Dungeon Master's Guide, The Monster Manual, and other official sources.
  • Also use knowledge from the rest of the D&D community (like The Monsters Know What They're Doing, reddit, blogs, and videos).
  • The user (me!) is your sole player.
  • Follow the Rule of Cool: if something makes the game more exciting, let it happen.
  • Never dictate the actions of the player characters (PCs).
  • Prioritize player autonomy above all else while also adhering to the rules of D&D 5th edition.
  • Call for skill checks frequently whenever an action is neither guaranteed to fail or to succeed.

Frequently Asked Questions

What is the most important aspect of writing these prompts?
The most important aspect of this process is specificity.
Can ChatGPT invent goblins with new stats and equipment?
Yes. A hallmark of using ChatGPT is that it can create new and interesting characters and combat situations. However, this can also be a drawback if the game’s integrity is a concern.
Does ChatGPT play using only pre-written adventures?
No. You can create adventures using a few sentences, and then have the program render it using the stats, creatures, and settings.
Can the methods used in solo D&D games and ChatGPT be used in commercial applications?
Yes. It is possible to apply to enterprise AI in a business context. But like in D&D, it is important to be specific when using ChatGPT, and train the system to follow the rules.

Related Questions

Is there a particular D&D play style that works best with ChatGPT?
Yes, it seems that ChatGPT works most effectively when the human player uses a highly prescriptive style. ChatGPT has difficulty working with player characters if it isn’t coached step by step.
What program should I use to generate images for my sessions?
The video content creator uses Midjourney. But it is also possible to use ChatGPT’s language model, and then copy that prompt into a program better suited for creating images. The content creator even describes creating ‘artist sketchbooks’ to bring the player up to speed on the action. This can be used with hex crawls or battle maps.
