Luck Rolls in D&D May Assist You Become a Superior Dungeon Master

When I am a Dungeon Master, I historically shied away from significant use of luck during my D&D adventures. I tended was for narrative flow and session development to be determined by deliberate decisions instead of random chance. That said, I decided to alter my method, and I'm very happy with the result.

The Catalyst: Seeing a Custom Mechanic

A well-known actual-play show showcases a DM who frequently asks for "chance rolls" from the players. The process entails picking a specific dice and outlining possible results contingent on the number. This is essentially no different from using a pre-generated chart, these get invented in the moment when a course of events has no predetermined conclusion.

I chose to experiment with this approach at my own game, mainly because it seemed novel and provided a departure from my usual habits. The outcome were remarkable, prompting me to reflect on the ongoing tension between pre-determination and improvisation in a D&D campaign.

A Powerful Session Moment

In a recent session, my group had concluded a massive conflict. When the dust settled, a player asked about two key NPCs—a pair—had survived. Instead of picking a fate, I asked for a roll. I told the player to make a twenty-sided die roll. The stakes were: on a 1-4, both died; a middling roll, a single one succumbed; a high roll, they made it.

The player rolled a 4. This resulted in a profoundly poignant scene where the party came upon the remains of their companions, forever clasped together in their final moments. The cleric performed a ceremony, which was particularly meaningful due to earlier character interactions. As a parting gesture, I improvised that the NPCs' bodies were suddenly restored, showing a magical Prayer Bead. I randomized, the item's contained spell was precisely what the group needed to solve another critical story problem. One just script such serendipitous story beats.

Honing On-the-Spot Skills

This incident caused me to question if improvisation and thinking on your feet are in fact the beating heart of this game. While you are a prep-heavy DM, your skill to pivot may atrophy. Players frequently take delight in upending the most detailed narratives. Therefore, a skilled DM must be able to pivot effectively and create scenarios on the fly.

Utilizing similar mechanics is a great way to train these talents without going completely outside your preparation. The strategy is to use them for minor decisions that have a limited impact on the overarching story. To illustrate, I wouldn't use it to decide if the main villain is a secret enemy. But, I might use it to decide whether the PCs reach a location moments before a major incident takes place.

Empowering Player Agency

Spontaneous randomization also serves to maintain tension and create the impression that the adventure is responsive, evolving based on their choices as they play. It prevents the sense that they are merely actors in a rigidly planned story, thereby strengthening the shared aspect of storytelling.

This philosophy has always been part of the core of D&D. Original D&D were reliant on encounter generators, which suited a playstyle focused on exploration. Even though modern D&D often emphasizes story and character, leading many DMs to feel they need exhaustive notes, that may not be the best approach.

Striking the Right Balance

It is perfectly nothing wrong with doing your prep. But, there is also nothing wrong with relinquishing control and letting the dice to guide minor details in place of you. Control is a significant part of a DM's job. We need it to facilitate play, yet we can be reluctant to cede it, even when doing so might improve the game.

A piece of advice is this: Don't be afraid of relinquishing a bit of the reins. Try a little chance for inconsequential story elements. You might just create that the organic story beat is infinitely more rewarding than anything you would have pre-written in advance.
