As a Dungeon Master, I traditionally avoided extensive use of randomization during my D&D sessions. I preferred was for narrative flow and session development to be guided by deliberate decisions instead of the roll of a die. However, I decided to try something different, and I'm truly pleased with the outcome.

The Spark: Watching a Custom Mechanic

An influential actual-play show showcases a DM who frequently requests "luck rolls" from the adventurers. He does this by choosing a specific dice and assigning consequences tied to the result. This is essentially no different from rolling on a pre-generated chart, these are created in the moment when a course of events lacks a obvious conclusion.

I opted to test this method at my own table, primarily because it seemed engaging and provided a break from my usual habits. The outcome were eye-opening, prompting me to reflect on the perennial dynamic between pre-determination and improvisation in a tabletop session.

A Powerful In-Game Example

In a recent session, my group had survived a city-wide battle. Afterwards, a player inquired after two key NPCs—a pair—had survived. In place of choosing an outcome, I handed it over to chance. I told the player to make a twenty-sided die roll. The stakes were: on a 1-4, both died; a middling roll, only one succumbed; on a 10+, they survived.

Fate decreed a 4. This resulted in a deeply moving sequence where the adventurers came upon the corpses of their companions, still holding hands in their final moments. The cleric conducted funeral rites, which was particularly meaningful due to previous story developments. As a final gesture, I decided that the remains were suddenly transformed, revealing a magical Prayer Bead. I rolled for, the item's contained spell was precisely what the group required to address another major situation. You simply plan these kinds of perfect story beats.

Improving Your Improvisation

This experience caused me to question if chance and making it up are in fact the essence of this game. Although you are a prep-heavy DM, your improvisation muscles may atrophy. Groups reliably excel at ignoring the most carefully laid plans. Therefore, a good DM must be able to adapt swiftly and invent content on the fly.

Employing on-the-spot randomization is a fantastic way to develop these skills without straying too much outside your usual style. The strategy is to use them for low-stakes decisions that don't fundamentally change the session's primary direction. As an example, I would avoid using it to decide if the central plot figure is a traitor. However, I might use it to determine whether the characters enter a room moments before a critical event unfolds.

Empowering Collaborative Storytelling

This technique also works to maintain tension and foster the feeling that the game world is dynamic, progressing in reaction to their decisions as they play. It reduces the sense that they are merely pawns in a pre-written script, thereby bolstering the shared nature of storytelling.

This philosophy has always been embedded in the core of D&D. The game's roots were filled with encounter generators, which suited a playstyle focused on dungeon crawling. Even though modern D&D often prioritizes narrative and role-play, leading many DMs to feel they need exhaustive notes, it's not necessarily the only path.

Finding the Healthy Equilibrium

Absolutely no issue with doing your prep. Yet, equally valid no issue with letting go and permitting the dice to determine certain outcomes rather than you. Authority is a big part of a DM's role. We need it to facilitate play, yet we can be reluctant to release it, at times when doing so can lead to great moments.

The core suggestion is this: Do not fear of temporarily losing control. Experiment with a little improvisation for inconsequential outcomes. It may find that the unexpected outcome is far more powerful than anything you might have scripted on your own.
