As a game master, I historically shied away from extensive use of luck during my Dungeons & Dragons games. I preferred was for the plot and session development to be determined by player choice as opposed to random chance. Recently, I decided to alter my method, and I'm very pleased with the outcome.

The Inspiration: Seeing a Custom Mechanic

A well-known actual-play show utilizes a DM who regularly requests "chance rolls" from the players. He does this by selecting a type of die and assigning consequences based on the result. It's fundamentally no unlike consulting a pre-generated chart, these are created on the spot when a player's action lacks a clear resolution.

I decided to try this approach at my own session, mostly because it seemed interesting and provided a departure from my usual habits. The results were remarkable, prompting me to reconsider the perennial tension between preparation and improvisation in a tabletop session.

A Memorable Session Moment

At a session, my party had survived a large-scale conflict. Afterwards, a cleric character asked about two friendly NPCs—a sibling duo—had made it. Rather than picking a fate, I asked for a roll. I instructed the player to make a twenty-sided die roll. The possible results were: on a 1-4, both would perish; on a 5-9, only one succumbed; a high roll, they both lived.

The player rolled a 4. This led to a profoundly emotional sequence where the adventurers found the corpses of their allies, forever united in death. The party conducted a ceremony, which was especially powerful due to prior roleplaying. As a parting gesture, I improvised that the forms were strangely restored, revealing a magical Prayer Bead. I randomized, the bead's contained spell was perfectly what the party lacked to address another critical quest obstacle. It's impossible to script such perfect moments.

Sharpening On-the-Spot Skills

This incident caused me to question if chance and making it up are in fact the essence of this game. Even if you are a meticulously planning DM, your improvisation muscles can rust. Groups often excel at derailing the most detailed plots. Therefore, a good DM must be able to adapt swiftly and fabricate details in the moment.

Employing luck rolls is a fantastic way to develop these talents without straying too much outside your preparation. The trick is to deploy them for minor situations that won't drastically alter the campaign's main plot. For instance, I would not employ it to establish if the main villain is a secret enemy. Instead, I might use it to decide whether the party arrive just in time to see a major incident occurs.

Enhancing Shared Narrative

Luck rolls also serves to keep players engaged and cultivate the sensation that the story is alive, shaping based on their decisions as they play. It reduces the sense that they are merely characters in a rigidly planned story, thereby enhancing the cooperative aspect of storytelling.

This approach has historically been embedded in the original design. Early editions were enamored with random tables, which fit a game focused on exploration. Even though modern D&D tends to focuses on plot-driven play, leading many DMs to feel they must prep extensively, it's not necessarily the required method.

Finding the Healthy Equilibrium

Absolutely nothing wrong with thorough preparation. Yet, equally valid no problem with letting go and permitting the whim of chance to determine certain outcomes instead of you. Authority is a big factor in a DM's job. We require it to run the game, yet we often struggle to give some up, in situations where doing so might improve the game.

The core suggestion is this: Do not fear of letting go of the reins. Experiment with a little randomness for minor outcomes. It may discover that the organic story beat is far more memorable than anything you would have planned in advance.
