Chance Rolls in D&D May Assist You Become a Superior Dungeon Master
As a Dungeon Master, I usually steered clear of heavy use of luck during my Dungeons & Dragons sessions. My preference was for story direction and session development to be determined by player choice instead of random chance. That said, I chose to try something different, and I'm truly pleased with the outcome.
The Spark: Observing an Improvised Tool
An influential podcast features a DM who regularly asks for "chance rolls" from the players. The process entails picking a type of die and outlining potential outcomes based on the number. It's at its core no unlike rolling on a pre-generated chart, these are devised in the moment when a player's action doesn't have a clear resolution.
I chose to experiment with this approach at my own table, primarily because it looked novel and presented a change from my usual habits. The experience were remarkable, prompting me to think deeply about the often-debated tension between planning and improvisation in a D&D campaign.
A Powerful Session Moment
At a session, my players had concluded a city-wide conflict. Afterwards, a cleric character asked about two friendly NPCs—a sibling duo—had made it. In place of picking a fate, I handed it over to chance. I told the player to make a twenty-sided die roll. The possible results were: on a 1-4, both would perish; a middling roll, a single one would die; a high roll, they made it.
The die came up a 4. This led to a deeply poignant sequence where the characters came upon the remains of their friends, still united in death. The group performed last rites, which was uniquely significant due to earlier story developments. In a concluding reward, I improvised that the remains were suddenly restored, containing a magical Prayer Bead. By chance, the item's magical effect was perfectly what the party lacked to resolve another critical quest obstacle. You simply orchestrate this type of magical coincidences.
Honing DM Agility
This incident made me wonder if improvisation and thinking on your feet are actually the core of D&D. Although you are a detail-oriented DM, your improvisation muscles need exercise. Adventurers often find joy in derailing the best constructed narratives. Therefore, a good DM has to be able to adapt swiftly and invent details in the moment.
Using similar mechanics is a excellent way to train these skills without venturing too far outside your usual style. The trick is to use them for minor circumstances that don't fundamentally change the campaign's main plot. To illustrate, I would avoid using it to establish if the king's advisor is a traitor. But, I might use it to figure out whether the party reach a location right after a critical event unfolds.
Empowering Shared Narrative
Spontaneous randomization also helps keep players engaged and create the feeling that the story is alive, shaping based on their choices in real-time. It combats the feeling that they are merely characters in a DM's sole story, thereby strengthening the shared aspect of roleplaying.
Randomization has always been embedded in the original design. Original D&D were filled with random tables, which suited a playstyle focused on dungeon crawling. Even though modern D&D often focuses on story and character, leading many DMs to feel they must prep extensively, this isn't always the required method.
Achieving the Right Balance
There is absolutely no issue with doing your prep. However, equally valid no problem with letting go and letting the dice to decide some things instead of you. Direction is a big factor in a DM's job. We need it to manage the world, yet we frequently find it hard to cede it, even when doing so could be beneficial.
A piece of suggestion is this: Do not fear of relinquishing a bit of your plan. Experiment with a little chance for smaller story elements. The result could create that the surprising result is infinitely more memorable than anything you could have scripted on your own.
