4 Great Ideas for One on One Games, Part 2

Thumbnail image by David Edwards

In the past weeks my article on why you should try One on One D&D and How to do it received quite a lot of attention. What does this mean? It clearly indicates that people are going out of their way and looking for ways to still play D&D while doing social distancing. Playing One on One (or duet as it is also called) greatly simplifies the whole process. Now, what happens when you are ready to run a game for this other person but you still don’t know the story arc you are going to make them go through? That’s what this article is all about! I’m here to give you 4 great ideas you can easily expand on which can give you an awesome starting point, or maybe even a whole campaign.

The idea behind this article will be to pitch each idea while trying to convince you through bullet points on all the best aspects of using it for your game. If possible, a starting adventure pitch will also be offered. This will create an introduction to it while leaving the doors open to continue it as long as you want.

The Thieves’ Guild

Don’t corner yourself thinking that being part of a thieves’ guild means the player must play a rogue. While their subclasses might be some of the better choices for the character to be, there are numerous alternatives. You can play a barbarian brute as well, a shadowy ranger that communicates with sewer rats, a fungi druid, a dexterous fighter, and many other things. With a good enough backstory, anything can fit the theme.

Starting the adventure

The kingpin of the capital city you live in calls for a special meeting with the player character. They are planning the next move! With the Day of Harvest rapidly coming, the thieves{ guild must prepare to infiltrate the masquerade happening in the Bassabet Villa. The Bassabet are the wealthiest nobles in the city, and they are rumored to have a vault filled to the very top with gold and proof of their past deals. Those nobles sure have a reason why they’ve reached their status this fast. And why is it they hate the Thieves’ Guild so much?

The player character has a whole week to plan the mission. Will it be made as a stealthy heist, or should the whole guild charge towards it breaking into the party and claiming access to the vault? Much investigation needs to be made, as well as some talks with contacts from the Thieves’ Guild leader to gather not only clues, but also the necessary equipment for the mission.

Why should you use this idea?

  • Playing as a member of a Thieves’ Guild allows the character to play someone who can lean towards the neutral or evil alignment with ease.
  • The player gets to plan a heist from the ground up
  • You can steal lots of things to create the city and the noble manor from already existing D&D modules. Even Dyson Logos has some great manors maps to use.
  • Both the DM and the player can mold this adventure with ease to make the nobles the bad corrupt guys, or for the player to be playing as the evil in the campaign.
  • You can take some inspiration from one of my articles on how to create an evil/Mafia-like organization here

Harry Potter-like school of adventurers and/or sorcery

Have you ever wanted to roleplay the life in a Harry Potter-like school? Even though there may be far better TTRPGs to create this feel, D&D can make a pretty good job replicating it. The fact you are playing One on One means you can focus on the PC’s relationship with other students. Does the player want it to be a fully magic focused school, limiting the class possibilities or do they want it to be a bit more open, and have it be a school for adventurers? Both options include very similar settings meaning you can pre-plan most of the school as a DM before the game begins. Or even better! You can create the school with your player!

Why should you use this idea?

  • If you ever wanted to play some sort of slice of life D&D roleplay, this may be what you are looking for.
  • Infinite possibilities regarding sidekicks with the inclusion of classmates.
  • Classes that take player characters to different locations to defeat beasts. You can even create great cinematic battles in which lots of students fight against one big evil.
  • I created an entire article you can use to give the campaign this feel. You can access it here
  • The inclusion of houses in the same way Harry Potter does can create a great sense of belonging to the player character, as well as rivalry against the other houses.

To track a Serial Killer

Tracking a serial killer can easily become a great One on One adventure. You can make it last as long as you want and adapt it to the specific person playing with you. You can make the serial killer be something similar to Jack the Ripper, the Black Widows, or whatever strikes your mind. As gory or as PG-13 as you like. The player will investigate this mystery by following the clues that may end up leading to dangerous places. At some point the PC will finally encounter the serial killer, and it is then when the final confrontation will occur.

Starting the adventure

The city count calls for the player character. Even though numerous tales of Graz’zt cultists have appeared throughout the city in these last years, something weird has also begun to happen these past weeks.  Three different nobles were found dead at their places. All of them in sitting positions reading books. Next to each of their corpses a note signed by The Taleteller. It is believed the serial killer is trying to leave a message throughout the books left in each of the corpses. Who is this serial killer connected to? Is there a bigger goal? Is it connected to the cultists? Only one way to find out.

Why should you use this idea?

  • The player character gets to feel like a detective
  • One can easily add a Watson-like sidekick to the adventure.
  • You can give clues in the form of letters as handouts.
  • The player can choose if they want to play a detective that is more like Sherlock Holmes, something more of a private investigator, or maybe a vigilante-like detective.
  • You can use some tips from the City of Mist TTRPG on how to create a great mystery

The Adventurer’s Guild

If you plan to go for something simple with which you can easily change the game’s theme, why not have the player be part of an adventurers’ or hunters’ guild? This does not only allow you as a DM to give the player fellow partners as sidekicks, but you can also run the adventure as a Monster of the Week campaign. What’s even better, you can create some sort of bulletin board with two or three missions to let the player decide what to do next. Maybe going for one mission instead of the others generates new complications in the other missions. You can learn more on how to properly do that here.

Why should you use this idea?

  • Allows for any kind of adventure genre the DM and the player may want to play at any time
  • You can play in a Monster of the Week episodic style.
  • The DM can create several NPCs for the player to decide each time who to pick for the adventure as a sidekick.
  • Pretty much any module, adventurer’s league adventure and/or dungeon can be used for this style of play.
  • This can be used to create some sort of West Marches campaign. Click here to understand what that means, and here if you want to learn more about hexcrawling.


Playing one on one (or duet) D&D is a fantastic way to pass the time and forget you are stuck at home. Fortunately, this style of game can be easily played with one other person that lives with you or someone over the Internet.
