When I am a game master, I historically shied away from extensive use of chance during my D&D sessions. I tended was for story direction and session development to be guided by player choice instead of pure luck. However, I chose to alter my method, and I'm incredibly glad I did.

The Spark: Observing 'Luck Rolls'

A popular podcast utilizes a DM who often asks for "fate rolls" from the adventurers. He does this by choosing a polyhedral and outlining potential outcomes contingent on the result. This is at its core no distinct from using a pre-generated chart, these get invented spontaneously when a character's decision has no clear conclusion.

I decided to try this method at my own game, mainly because it appeared engaging and presented a change from my normal practice. The experience were fantastic, prompting me to reconsider the often-debated tension between planning and improvisation in a D&D campaign.

A Powerful Story Beat

In a recent session, my group had survived a large-scale conflict. Afterwards, a player wondered if two key NPCs—a brother and sister—had lived. Rather than choosing an outcome, I asked for a roll. I asked the player to make a twenty-sided die roll. I defined the outcomes as: a low roll, both were killed; a middling roll, only one would die; a high roll, they both lived.

The player rolled a 4. This led to a incredibly poignant sequence where the party discovered the corpses of their companions, forever holding hands in their final moments. The party held a ceremony, which was uniquely powerful due to previous story developments. As a final reward, I chose that the remains were miraculously restored, revealing a spell-storing object. I randomized, the bead's magical effect was exactly what the party lacked to address another major quest obstacle. You simply orchestrate this type of perfect moments.

Improving Your Improvisation

This incident made me wonder if chance and making it up are in fact the essence of this game. Even if you are a prep-heavy DM, your improvisation muscles need exercise. Groups frequently excel at upending the best constructed plots. Therefore, a skilled DM needs to be able to pivot effectively and create scenarios in real-time.

Using luck rolls is a great way to develop these talents without going completely outside your preparation. The key is to apply them for minor situations that have a limited impact on the overarching story. As an example, I would not employ it to determine if the main villain is a traitor. But, I might use it to determine whether the party arrive moments before a critical event unfolds.

Strengthening Shared Narrative

Luck rolls also serves to maintain tension and create the feeling that the adventure is alive, progressing according to their choices in real-time. It combats the perception that they are merely actors in a pre-written script, thereby strengthening the cooperative aspect of storytelling.

This philosophy has historically been embedded in the core of D&D. Original D&D were reliant on encounter generators, which made sense for a game focused on dungeon crawling. Although current D&D often focuses on plot-driven play, leading many DMs to feel they need exhaustive notes, this isn't always the required method.

Finding the Sweet Spot

It is perfectly no problem with being prepared. However, equally valid no issue with relinquishing control and permitting the whim of chance to guide minor details instead of you. Direction is a big aspect of a DM's job. We require it to run the game, yet we can be reluctant to release it, even when doing so can lead to great moments.

The core recommendation is this: Have no fear of relinquishing a bit of the reins. Experiment with a little improvisation for inconsequential details. It may find that the unexpected outcome is far more rewarding than anything you might have scripted in advance.
