Chance Rolls in D&D May Assist You Become a Superior Dungeon Master

In my role as a Dungeon Master, I traditionally shied away from significant use of randomization during my D&D adventures. I tended was for narrative flow and what happened in a game to be shaped by character actions instead of pure luck. However, I decided to change my approach, and I'm incredibly pleased with the outcome.

The Inspiration: Watching an Improvised Tool

A popular streamed game showcases a DM who regularly calls for "luck rolls" from the adventurers. This involves picking a type of die and outlining possible results based on the number. This is at its core no distinct from consulting a random table, these get invented on the spot when a course of events has no predetermined resolution.

I decided to try this approach at my own table, mainly because it seemed interesting and offered a break from my normal practice. The outcome were remarkable, prompting me to think deeply about the often-debated balance between preparation and randomization in a tabletop session.

A Powerful Session Moment

During one session, my party had survived a large-scale conflict. Afterwards, a cleric character asked about two friendly NPCs—a pair—had lived. In place of picking a fate, I handed it over to chance. I instructed the player to roll a d20. I defined the outcomes as: on a 1-4, both would perish; on a 5-9, only one would die; on a 10+, they both lived.

The player rolled a 4. This triggered a deeply poignant scene where the characters discovered the bodies of their allies, still holding hands in their final moments. The cleric performed a ceremony, which was uniquely significant due to previous roleplaying. In a concluding reward, I decided that the NPCs' bodies were strangely restored, showing a enchanted item. I rolled for, the item's magical effect was precisely what the group required to resolve another pressing story problem. It's impossible to orchestrate this type of perfect coincidences.

Improving Your Improvisation

This event caused me to question if randomization and making it up are truly the beating heart of tabletop RPGs. Although you are a meticulously planning DM, your skill to pivot need exercise. Adventurers reliably excel at derailing the best constructed plans. Therefore, a good DM has to be able to think quickly and create scenarios in real-time.

Employing luck rolls is a great way to develop these skills without going completely outside your preparation. The strategy is to apply them for low-stakes situations that don't fundamentally change the campaign's main plot. For instance, I would avoid using it to establish if the king's advisor is a secret enemy. But, I might use it to decide whether the party enter a room just in time to see a major incident occurs.

Enhancing Player Agency

Luck rolls also helps make players feel invested and foster the feeling that the story is responsive, progressing based on their choices in real-time. It prevents the perception that they are merely actors in a rigidly planned story, thereby enhancing the cooperative nature of storytelling.

Randomization has always been part of the original design. Original D&D were filled with random tables, which suited a game focused on exploration. Even though contemporary D&D tends to emphasizes plot-driven play, leading many DMs to feel they must prep extensively, this isn't always the best approach.

Striking the Right Balance

It is perfectly no issue with being prepared. Yet, there is also no problem with relinquishing control and allowing the dice to decide some things instead of you. Control is a major factor in a DM's responsibilities. We require it to run the game, yet we can be reluctant to release it, at times when doing so could be beneficial.

My final recommendation is this: Don't be afraid of letting go of your plan. Try a little chance for minor outcomes. You might just find that the organic story beat is infinitely more powerful than anything you would have planned by yourself.
