Chance Rolls in Dungeons & Dragons Can Help You Be a More Effective Dungeon Master

As a game master, I usually steered clear of heavy use of chance during my tabletop roleplaying sessions. I tended was for story direction and session development to be determined by character actions instead of pure luck. That said, I decided to change my approach, and I'm truly glad I did.

The Catalyst: Observing 'Luck Rolls'

A well-known podcast utilizes a DM who regularly asks for "fate rolls" from the players. He does this by selecting a type of die and outlining potential outcomes based on the roll. While it's essentially no distinct from consulting a random table, these get invented spontaneously when a course of events lacks a predetermined resolution.

I chose to experiment with this technique at my own session, primarily because it seemed novel and provided a change from my usual habits. The outcome were fantastic, prompting me to think deeply about the often-debated tension between preparation and spontaneity in a D&D campaign.

A Memorable In-Game Example

In a recent session, my group had concluded a massive conflict. When the dust settled, a cleric character wondered if two friendly NPCs—a sibling duo—had made it. In place of choosing an outcome, I let the dice decide. I told the player to roll a d20. The stakes were: a low roll, both were killed; on a 5-9, a single one would die; a high roll, they made it.

The player rolled a 4. This resulted in a profoundly moving moment where the adventurers came upon the bodies of their allies, forever holding hands in their final moments. The group performed a ceremony, which was especially meaningful due to prior character interactions. As a final reward, I decided that the NPCs' bodies were suddenly transformed, revealing a magical Prayer Bead. I rolled for, the item's magical effect was precisely what the party lacked to resolve another major story problem. It's impossible to plan these kinds of serendipitous story beats.

Honing On-the-Spot Skills

This experience led me to ponder if randomization and thinking on your feet are in fact the essence of D&D. Even if you are a detail-oriented DM, your improvisation muscles may atrophy. Adventurers reliably take delight in upending the best constructed narratives. Therefore, a good DM must be able to pivot effectively and create content on the fly.

Utilizing luck rolls is a fantastic way to train these talents without straying too much outside your comfort zone. The strategy is to deploy them for small-scale decisions that don't fundamentally change the session's primary direction. To illustrate, I wouldn't use it to establish if the main villain is a secret enemy. However, I could use it to determine if the characters enter a room moments before a major incident occurs.

Enhancing Collaborative Storytelling

Luck rolls also serves to maintain tension and cultivate the feeling that the story is dynamic, progressing based on their choices in real-time. It combats the sense that they are merely actors in a rigidly planned story, thereby strengthening the cooperative foundation of storytelling.

This philosophy has historically been integral to the original design. Early editions were enamored with charts, which made sense for a game focused on exploration. Even though contemporary D&D frequently focuses on narrative and role-play, leading many DMs to feel they must prep extensively, it's not necessarily the required method.

Finding the Healthy Equilibrium

It is perfectly nothing wrong with being prepared. Yet, there is also nothing wrong with letting go and letting the dice to determine certain outcomes instead of you. Control is a major factor in a DM's role. We require it to facilitate play, yet we frequently find it hard to release it, in situations where doing so can lead to great moments.

The core suggestion is this: Don't be afraid of letting go of the reins. Experiment with a little randomness for smaller story elements. You might just discover that the organic story beat is far more powerful than anything you could have planned in advance.
