Chance Rolls in D&D Can Help You Be a Better DM

As a DM, I usually shied away from significant use of randomization during my tabletop roleplaying sessions. I preferred was for the plot and what happened in a game to be shaped by character actions instead of the roll of a die. Recently, I decided to try something different, and I'm very glad I did.

The Spark: Seeing 'Luck Rolls'

A well-known actual-play show utilizes a DM who often calls for "luck rolls" from the players. The process entails selecting a specific dice and outlining potential outcomes tied to the number. This is fundamentally no unlike rolling on a pre-generated chart, these get invented spontaneously when a player's action has no clear outcome.

I chose to experiment with this approach at my own table, primarily because it appeared interesting and presented a departure from my standard routine. The experience were remarkable, prompting me to think deeply about the often-debated dynamic between planning and spontaneity in a tabletop session.

A Memorable In-Game Example

During one session, my players had concluded a city-wide battle. When the dust settled, a player wondered if two beloved NPCs—a brother and sister—had made it. In place of choosing an outcome, I asked for a roll. I asked the player to roll a d20. I defined the outcomes as: on a 1-4, both were killed; a middling roll, a single one would die; a high roll, they made it.

The die came up a 4. This resulted in a incredibly poignant sequence where the characters discovered the corpses of their companions, forever united in their final moments. The cleric performed funeral rites, which was especially meaningful due to previous story developments. In a concluding reward, I decided that the forms were strangely restored, containing a spell-storing object. By chance, the bead's magical effect was exactly what the party required to resolve another critical quest obstacle. It's impossible to orchestrate these kinds of serendipitous coincidences.

Sharpening Your Improvisation

This event caused me to question if improvisation and thinking on your feet are actually the beating heart of this game. Even if you are a detail-oriented DM, your improvisation muscles need exercise. Groups frequently take delight in upending the most carefully laid plots. Therefore, a good DM has to be able to think quickly and fabricate details in real-time.

Using similar mechanics is a fantastic way to practice these abilities without straying too much outside your comfort zone. The trick is to apply them for low-stakes circumstances that won't drastically alter the session's primary direction. As an example, I would avoid using it to decide if the main villain is a traitor. Instead, I would consider using it to determine if the party arrive right after a major incident unfolds.

Strengthening Shared Narrative

This technique also helps maintain tension and cultivate the impression that the story is responsive, shaping based on their actions as they play. It reduces the feeling that they are merely actors in a DM's sole script, thereby strengthening the collaborative foundation of storytelling.

This approach has long been part of the core of D&D. Original D&D were filled with random tables, which suited a playstyle focused on dungeon crawling. Even though contemporary D&D tends to focuses on plot-driven play, leading many DMs to feel they must prep extensively, it's not necessarily the only path.

Finding the Healthy Equilibrium

Absolutely no issue with being prepared. Yet, equally valid nothing wrong with letting go and letting the whim of chance to determine certain outcomes rather than you. Direction is a big part of a DM's responsibilities. We require it to facilitate play, yet we often struggle to give some up, even when doing so can lead to great moments.

The core suggestion is this: Do not fear of relinquishing a bit of your plan. Embrace a little improvisation for inconsequential outcomes. The result could find that the organic story beat is significantly more powerful than anything you might have scripted by yourself.
