Controlled randomness as a tool in adventure/character creation

Last night, I was working on the first level of a multi-stage dungeon for an upcoming D&D 5e session I’m running (I’ll be sure to put up the walkthrough after it’s over). I realized I was turning to a tool I’ve often leveraged at other times I create adventures or characters in RPGs: controlled randomness. I thought it may be useful to have a post on this tool for others, and I apologize if this is incredibly obvious to everyone but me.

What is controlled randomness? It is the use of random decisions with a general pre-determined framework to add depth and flavor to a RPG creation. That sounds like a line from an academic article, but I think it gets the definition. In many RPGs there are tables of adventure elements, character backgrounds and the like, in which the player rolls a dice to determine what detail to use. Controlled randomness uses these, but re-rolls as needed to find something that generally fits with the pre-determined framework.

I first systematized this when my old group and I were creating characters for Star Wars: Edge of the Empire. This is a fun character creation process (which I’ve discussed before), and involves detailing the motivations and complications behind the character. I was creating Arkdo, a Duros explorer I’ll discuss in a future Origin Stories post. I rolled for his motivation, didn’t like the result, and re-rolled it. One of the fellow players teased me for doing this, so I explained my reasoning.

As I envisioned him, Arkdo was basically a good guy who ended up on the wrong side of the law because of his ideals. I wasn’t sure how to flesh that out, so I rolled on the tables until something useful came up: dedication to the Jedi. Now, Arkdo wasn’t a Jedi, but he did admire the order and attempted to preserve their memory.

Thanks to controlled randomness, I had a cool backstory for my character. I knew generally what I wanted, but if I had just picked the most obvious motivation I wouldn’t have gone with his dedication to the Jedi. By re-rolling on the table within a pre-set idea, I was able to add more layers to this character.

Another example was my creation of Fonken, a gnome wizard in D&D 5e (this will be another future Origin Stories post). I wanted a LG gnome with a sage background, but beyond that I didn’t have much. D&D 5e includes tables to rolls for different aspects of the character’s background, including bonds, motivations and flaws. For flaw, I rolled something about reacting to a horrible monster’s appearance by trying to study it. With this roll, the character clicked, and I envisioned him as a cross between Ray Stantz from Ghostbusters and Dale Cooper from Twin Peaks. He was a lot of fun to play, and I even revived an older Fonken for one of my own adventures I created.

This reveals another reason to value controlled randomness: adding flaws. Fonken’s inquisitiveness led him to take unwise risks. This added some complications to my group’s adventures, but overall made things more fun. I’ve talked before about the value of adding flaws to D&D characters, and this is one good way to do it.

Controlled randomness works for adventure creation as well. In The Shadow in the Woods–one of my home-brew adventures–I had a general sense for a dungeon the group would explore. It was the subterranean dwelling of a hag who had summoned a beast from the Shadowfell. But that was it. So I used the encounter and dungeon creation tables in the DMG. I rolled up a castle submerged in a swamp as the setting. This gave me a lot to play with, as the corridors and rooms twisted at odd angles thanks to the castle sinking at an odd angle. I also was able to use this to create a dramatic escape challenge at the end. And I used the random dungeon tables to create a confusing series of passages and rooms that, thanks to my pre-conceived idea, followed the basic form of a multi-level tower connected by oddly-angled corridors.

I used controlled randomness to even greater effect in the dungeon I’m currently finishing (I don’t want to give too many details in case any players read this blog…). In this case, I knew the first level of the dungeon would be the basement of a ruined wizard’s tower. I wanted it to feel like part of a ruined structure, so I planned out the corridors and rooms myself. I also came up with a general idea for what each section would be: a cluster of rooms to entertain guests, a cluster for research, machinery, etc. I also had an idea of the combat encounters, traps and hazards the group would face so I placed them accordingly.

This is where controlled randomness came in. For each cluster of rooms, I rolled on the DMG random dungeon tables to determine the specific nature of the room, re-rolling when the result didn’t fit. I also rolled on the table for the rooms’ current states. This added some nice randomness, as I pictured certain rooms crumbling or becoming overgrown with vines, while others were sealed up and lest in a pristine state. The DMG tricks and obstacles tables were also useful; I had a few rooms that would contain some non-combat encounter, and these tables helped me come up with surprising challenges for the players. In this way, controlled randomness gave me a fleshed out dungeon that still felt coherent.

So new players and DMs may find this tool, controlled randomness of use. Come up with a basic idea for a character or dungeon. Then roll on the appropriate table. Re-roll if the result makes no sense with your idea, but push yourself to keep results that are unexpected or complicate your plans. I’d love to hear from anyone who tries this.
