Chance Rolls in Dungeons & Dragons May Assist You Be a Superior DM

As a Dungeon Master, I historically avoided heavy use of luck during my D&D sessions. I preferred was for the plot and session development to be determined by player choice as opposed to the roll of a die. Recently, I decided to change my approach, and I'm very pleased with the outcome.

The Spark: Observing 'Luck Rolls'

A well-known streamed game features a DM who often calls for "fate rolls" from the participants. He does this by choosing a polyhedral and outlining potential outcomes tied to the result. This is at its core no distinct from using a random table, these are devised in the moment when a player's action has no obvious conclusion.

I chose to experiment with this approach at my own game, primarily because it seemed interesting and provided a change from my usual habits. The outcome were remarkable, prompting me to reflect on the perennial balance between preparation and improvisation in a D&D campaign.

A Memorable Story Beat

During one session, my players had concluded a large-scale fight. When the dust settled, a player asked about two friendly NPCs—a sibling duo—had made it. In place of choosing an outcome, I asked for a roll. I asked the player to roll a d20. The possible results were: on a 1-4, both were killed; on a 5-9, a single one succumbed; a high roll, they survived.

The player rolled a 4. This led to a profoundly emotional sequence where the adventurers found the corpses of their companions, still united in their final moments. The party performed funeral rites, which was especially powerful due to prior character interactions. As a final reward, I decided that the remains were suddenly transformed, containing a enchanted item. I randomized, the item's contained spell was perfectly what the party required to resolve another pressing quest obstacle. You simply orchestrate these kinds of magical coincidences.

Sharpening DM Agility

This incident made me wonder if chance and spontaneity are in fact the beating heart of tabletop RPGs. While you are a prep-heavy DM, your ability to adapt may atrophy. Players frequently find joy in derailing the most detailed narratives. Therefore, a good DM needs to be able to pivot effectively and create scenarios in the moment.

Employing on-the-spot randomization is a great way to practice these skills without straying too much outside your comfort zone. The trick is to apply them for minor situations that won't drastically alter the campaign's main plot. To illustrate, I would not employ it to establish if the main villain is a traitor. But, I could use it to decide whether the PCs enter a room moments before a major incident unfolds.

Empowering Player Agency

Spontaneous randomization also serves to make players feel invested and create the feeling that the game world is responsive, evolving in reaction to their decisions as they play. It combats the sense that they are merely actors in a rigidly planned narrative, thereby enhancing the shared nature of roleplaying.

This approach has long been integral to the game's DNA. Early editions were reliant on encounter generators, which suited a playstyle focused on exploration. Even though modern D&D frequently emphasizes story and character, leading many DMs to feel they need exhaustive notes, this isn't always the only path.

Finding the Right Balance

Absolutely nothing wrong with doing your prep. However, there is also no issue with letting go and letting the whim of chance to guide minor details rather than you. Authority is a big factor in a DM's role. We require it to manage the world, yet we can be reluctant to cede it, in situations where doing so can lead to great moments.

A piece of suggestion is this: Don't be afraid of letting go of your plan. Embrace a little chance for inconsequential outcomes. The result could find that the unexpected outcome is far more powerful than anything you would have scripted by yourself.
