In my role as a Dungeon Master, I traditionally avoided extensive use of luck during my D&D adventures. My preference was for the plot and session development to be determined by deliberate decisions rather than random chance. Recently, I chose to alter my method, and I'm incredibly glad I did.

The Spark: Watching an Improvised Tool

A popular streamed game features a DM who often calls for "fate rolls" from the players. This involves selecting a type of die and defining possible results based on the result. While it's at its core no different from rolling on a pre-generated chart, these are devised on the spot when a player's action doesn't have a clear resolution.

I decided to try this method at my own session, primarily because it looked engaging and provided a departure from my normal practice. The results were eye-opening, prompting me to think deeply about the often-debated tension between preparation and spontaneity in a tabletop session.

A Powerful In-Game Example

In a recent session, my players had just emerged from a massive conflict. When the dust settled, a player wondered if two beloved NPCs—a pair—had survived. Instead of choosing an outcome, I asked for a roll. I instructed the player to make a twenty-sided die roll. The stakes were: a low roll, both died; a middling roll, only one succumbed; on a 10+, they survived.

The die came up a 4. This led to a profoundly poignant scene where the adventurers found the remains of their companions, still united in their final moments. The party conducted last rites, which was uniquely meaningful due to earlier roleplaying. In a concluding reward, I decided that the forms were miraculously transformed, showing a enchanted item. I randomized, the item's magical effect was precisely what the party lacked to solve another major situation. You simply script such perfect story beats.

Sharpening Your Improvisation

This experience led me to ponder if randomization and thinking on your feet are truly the essence of D&D. Although you are a detail-oriented DM, your ability to adapt need exercise. Players frequently excel at derailing the most detailed plans. Therefore, a good DM has to be able to think quickly and create details in the moment.

Using on-the-spot randomization is a great way to practice these skills without straying too much outside your comfort zone. The strategy is to deploy them for minor circumstances that don't fundamentally change the campaign's main plot. As an example, I would not employ it to determine if the central plot figure is a traitor. Instead, I might use it to figure out if the PCs enter a room right after a major incident takes place.

Empowering Player Agency

Spontaneous randomization also works to make players feel invested and create the feeling that the game world is responsive, evolving in reaction to their choices in real-time. It reduces the perception that they are merely actors in a rigidly planned narrative, thereby strengthening the shared nature of the game.

Randomization has always been embedded in the core of D&D. The game's roots were enamored with charts, which fit a playstyle focused on dungeon crawling. Although modern D&D often emphasizes narrative and role-play, leading many DMs to feel they need exhaustive notes, it's not necessarily the best approach.

Achieving the Sweet Spot

Absolutely nothing wrong with doing your prep. However, equally valid nothing wrong with relinquishing control and allowing the whim of chance to determine certain outcomes instead of you. Control is a big part of a DM's responsibilities. We need it to manage the world, yet we frequently find it hard to give some up, in situations where doing so can lead to great moments.

A piece of advice is this: Have no fear of relinquishing a bit of the reins. Embrace a little chance for minor details. It may find that the surprising result is significantly more rewarding than anything you could have pre-written in advance.
