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

In my role as a Dungeon Master, I historically avoided extensive use of luck during my Dungeons & Dragons sessions. I preferred was for the plot and session development to be shaped by deliberate decisions instead of pure luck. However, I opted to change my approach, and I'm very happy with the result.

The Spark: Watching a Custom Mechanic

An influential streamed game features a DM who regularly asks for "chance rolls" from the adventurers. This involves choosing a polyhedral and defining potential outcomes based on the roll. It's fundamentally no different from rolling on a random table, these get invented in the moment when a player's action has no predetermined resolution.

I opted to test this technique at my own game, mainly because it appeared novel and presented a change from my normal practice. The experience were fantastic, prompting me to reflect on the ongoing balance between planning and randomization in a tabletop session.

A Powerful Session Moment

During one session, my players had concluded a large-scale battle. When the dust settled, a player wondered if two friendly NPCs—a sibling duo—had survived. Instead of deciding myself, I asked for a roll. I asked the player to make a twenty-sided die roll. The stakes were: a low roll, both would perish; on a 5-9, only one succumbed; on a 10+, they both lived.

The player rolled a 4. This led to a incredibly emotional moment where the party discovered the bodies of their friends, still holding hands in their final moments. The party held last rites, which was particularly powerful due to earlier character interactions. In a concluding gesture, I decided that the forms were suddenly restored, showing a spell-storing object. I rolled for, the item's contained spell was exactly what the party required to solve another pressing story problem. You simply orchestrate such magical coincidences.

Improving Your Improvisation

This experience led me to ponder if randomization and making it up are truly the beating heart of this game. Even if you are a meticulously planning DM, your ability to adapt may atrophy. Adventurers reliably find joy in ignoring the most carefully laid plans. Therefore, a skilled DM must be able to think quickly and fabricate scenarios in real-time.

Employing luck rolls is a fantastic way to develop these talents without going completely outside your comfort zone. The strategy is to deploy them for low-stakes decisions that don't fundamentally change the campaign's main plot. For instance, I would avoid using it to decide if the main villain is a secret enemy. However, I might use it to decide whether the PCs enter a room right after a key action occurs.

Enhancing Player Agency

Luck rolls also serves to make players feel invested and cultivate the feeling that the game world is alive, progressing in reaction to their choices as they play. It reduces the perception that they are merely pawns in a DM's sole narrative, thereby strengthening the shared nature of the game.

Randomization has always been embedded in the original design. Early editions were reliant on encounter generators, which made sense for a game focused on dungeon crawling. While contemporary D&D frequently emphasizes narrative and role-play, leading many DMs to feel they require detailed plans, that may not be the best approach.

Achieving the Right Balance

Absolutely no problem with being prepared. Yet, there is also no problem with stepping back and permitting the rolls to determine certain outcomes in place of you. Direction is a major factor in a DM's job. We need it to facilitate play, yet we frequently find it hard to cede it, in situations where doing so can lead to great moments.

The core suggestion is this: Do not fear of relinquishing a bit of your plan. Experiment with a little improvisation for smaller story elements. You might just discover that the surprising result is significantly more memorable than anything you might have pre-written in advance.
