Chance Rolls in D&D Can Help You Become a More Effective Dungeon Master

In my role as a DM, I traditionally steered clear of heavy use of randomization during my tabletop roleplaying adventures. I preferred was for narrative flow and session development to be shaped by deliberate decisions rather than random chance. However, I decided to try something different, and I'm truly glad I did.

The Spark: Seeing 'Luck Rolls'

A well-known actual-play show utilizes a DM who frequently requests "fate rolls" from the adventurers. The process entails picking a type of die and defining potential outcomes tied to the number. This is at its core no different from rolling on a pre-generated chart, these get invented in the moment when a player's action lacks a clear outcome.

I decided to try this method at my own game, primarily because it appeared engaging and provided a break from my normal practice. The experience were fantastic, prompting me to think deeply about the ongoing balance between planning and randomization in a roleplaying game.

An Emotional Session Moment

In a recent session, my party had survived a city-wide fight. When the dust settled, a player wondered if two beloved NPCs—a pair—had made it. Rather than deciding myself, I asked for a roll. I asked the player to roll a d20. I defined the outcomes as: a low roll, both would perish; on a 5-9, a single one succumbed; a high roll, they survived.

Fate decreed a 4. This led to a deeply emotional sequence where the adventurers came upon the corpses of their friends, forever clasped together in death. The party performed a ceremony, which was uniquely meaningful due to earlier character interactions. In a concluding gesture, I chose that the forms were strangely restored, showing a enchanted item. By chance, the bead's contained spell was exactly what the party needed to solve another critical quest obstacle. You simply script these kinds of magical moments.

Improving Your Improvisation

This event caused me to question if improvisation and thinking on your feet are actually the core of D&D. Even if you are a detail-oriented DM, your ability to adapt need exercise. Groups reliably excel at derailing the best constructed narratives. Therefore, a skilled DM needs to be able to think quickly and create scenarios on the fly.

Using on-the-spot randomization is a fantastic way to train these talents without straying too much outside your preparation. The strategy is to use them for low-stakes circumstances that won't drastically alter the overarching story. To illustrate, I would not employ it to determine if the central plot figure is a secret enemy. But, I could use it to figure out if the characters enter a room right after a key action unfolds.

Enhancing Player Agency

Luck rolls also works to keep players engaged and cultivate the feeling that the adventure is alive, progressing according to their choices in real-time. It reduces the feeling that they are merely actors in a pre-written narrative, thereby strengthening the shared nature of roleplaying.

This philosophy has long been part of the original design. Original D&D were filled with charts, which suited a game focused on dungeon crawling. While modern D&D tends to focuses on plot-driven play, leading many DMs to feel they must prep extensively, this isn't always the only path.

Achieving the Right Balance

Absolutely nothing wrong with doing your prep. Yet, equally valid no problem with relinquishing control and allowing the dice to determine certain outcomes rather than you. Authority is a major factor in a DM's job. We use it to run the game, yet we can be reluctant to give some up, at times when doing so might improve the game.

My final recommendation is this: Have no fear of letting go of control. Try a little randomness for inconsequential details. The result could discover that the unexpected outcome is significantly more powerful than anything you could have planned on your own.
