Chance Rolls in Dungeons & Dragons Are Able to Aid You Become a More Effective DM

When I am a game master, I historically steered clear of heavy use of randomization during my Dungeons & Dragons games. I preferred was for story direction and what happened in a game to be determined by deliberate decisions instead of random chance. However, I decided to try something different, and I'm truly glad I did.

The Catalyst: Seeing 'Luck Rolls'

An influential streamed game showcases a DM who often requests "luck rolls" from the participants. The process entails choosing a polyhedral and assigning consequences tied to the number. While it's at its core no distinct from consulting a pre-generated chart, these are devised in the moment when a player's action doesn't have a obvious conclusion.

I chose to experiment with this approach at my own game, mostly because it appeared interesting and offered a departure from my usual habits. The experience were fantastic, prompting me to reflect on the ongoing tension between pre-determination and randomization in a D&D campaign.

A Memorable Session Moment

During one session, my group had just emerged from a massive battle. Later, a cleric character asked about two beloved NPCs—a pair—had lived. Rather than deciding myself, I asked for a roll. I asked the player to make a twenty-sided die roll. I defined the outcomes as: on a 1-4, both died; a middling roll, a single one succumbed; on a 10+, they made it.

The player rolled a 4. This led to a profoundly poignant sequence where the adventurers found the bodies of their friends, forever holding hands in their final moments. The group held last rites, which was uniquely significant due to previous character interactions. As a parting gesture, I decided that the forms were suddenly transformed, revealing a magical Prayer Bead. By chance, the bead's contained spell was precisely what the group required to solve another major quest obstacle. You simply orchestrate these kinds of magical story beats.

Sharpening Your Improvisation

This incident caused me to question if randomization and making it up are actually the beating heart of tabletop RPGs. While you are a meticulously planning DM, your ability to adapt can rust. Groups frequently excel at upending the most carefully laid narratives. Therefore, a skilled DM must be able to adapt swiftly and create scenarios in the moment.

Employing similar mechanics is a great way to train these talents without going completely outside your usual style. The trick is to use them for low-stakes circumstances that don't fundamentally change the campaign's main plot. For instance, I wouldn't use it to decide if the central plot figure is a traitor. However, I would consider using it to determine whether the party reach a location moments before a critical event occurs.

Strengthening Player Agency

Spontaneous randomization also helps maintain tension and cultivate the impression that the adventure is dynamic, evolving in reaction to their choices in real-time. It reduces the feeling that they are merely characters in a DM's sole script, thereby strengthening the cooperative foundation of roleplaying.

Randomization has historically been embedded in the original design. Early editions were reliant on encounter generators, which suited a playstyle focused on treasure hunting. Even though modern D&D often emphasizes narrative and role-play, leading many DMs to feel they must prep extensively, that may not be the best approach.

Finding the Right Balance

There is absolutely no issue with doing your prep. However, there is also no issue with stepping back and permitting the whim of chance to decide some things instead of you. Control is a significant part of a DM's job. We require it to facilitate play, yet we frequently find it hard to give some up, in situations where doing so can lead to great moments.

My final suggestion is this: Do not fear of relinquishing a bit of your plan. Embrace a little randomness for inconsequential outcomes. The result could discover that the unexpected outcome is far more memorable than anything you could have scripted on your own.
