Chance Rolls in D&D Can Help You Be a Superior DM

In my role as a game master, I traditionally steered clear of significant use of luck during my Dungeons & Dragons sessions. My preference was for the plot and what happened in a game to be determined by deliberate decisions instead of pure luck. However, I decided to alter my method, and I'm truly pleased with the outcome.

The Inspiration: Observing an Improvised Tool

An influential actual-play show features a DM who regularly calls for "luck rolls" from the players. This involves selecting a type of die and defining possible results tied to the result. This is at its core no unlike using a random table, these are created on the spot when a course of events doesn't have a obvious conclusion.

I opted to test this technique at my own game, primarily because it appeared engaging and presented a departure from my normal practice. The results were fantastic, prompting me to reconsider the perennial balance between preparation and spontaneity in a tabletop session.

An Emotional In-Game Example

During one session, my party had survived a massive fight. When the dust settled, a cleric character asked about two friendly NPCs—a brother and sister—had lived. Instead of choosing an outcome, I asked for a roll. I told the player to make a twenty-sided die roll. The possible results were: a low roll, both were killed; a middling roll, only one succumbed; on a 10+, they survived.

Fate decreed a 4. This resulted in a incredibly poignant moment where the characters discovered the remains of their allies, still clasped together in death. The group conducted a ceremony, which was particularly significant due to prior story developments. In a concluding gesture, I chose that the NPCs' bodies were miraculously transformed, revealing a enchanted item. I rolled for, the bead's magical effect was exactly what the group required to resolve another major quest obstacle. It's impossible to orchestrate such perfect coincidences.

Honing Your Improvisation

This incident made me wonder if chance and making it up are truly the core of this game. Even if you are a detail-oriented DM, your improvisation muscles need exercise. Players often find joy in ignoring the most detailed plans. Therefore, a good DM must be able to think quickly and invent details on the fly.

Utilizing on-the-spot randomization is a great way to train these abilities without straying too much outside your comfort zone. The strategy is to apply them for small-scale circumstances that won't drastically alter the campaign's main plot. To illustrate, I would avoid using it to decide if the central plot figure is a traitor. But, I might use it to determine if the characters enter a room moments before a key action takes place.

Enhancing Player Agency

Spontaneous randomization also works to make players feel invested and cultivate the impression that the game world is alive, shaping in reaction to their actions immediately. It prevents the perception that they are merely pawns in a DM's sole narrative, thereby bolstering the collaborative nature of the game.

This philosophy has long been part of the game's DNA. The game's roots were reliant on random tables, which suited a playstyle focused on exploration. Although contemporary D&D frequently prioritizes story and character, leading many DMs to feel they need exhaustive notes, that may not be the best approach.

Striking the Healthy Equilibrium

Absolutely no problem with being prepared. Yet, it's also fine no problem with stepping back and letting the dice to guide minor details in place of you. Authority is a significant factor in a DM's role. We need it to manage the world, yet we often struggle to give some up, in situations where doing so might improve the game.

My final suggestion is this: Don't be afraid of temporarily losing your plan. Experiment with a little chance for minor details. You might just create that the unexpected outcome is infinitely more memorable than anything you could have pre-written in advance.
