Chance Rolls in Dungeons & Dragons Are Able to Aid You Be a Better DM

When I am a game master, I usually shied away from extensive use of randomization during my tabletop roleplaying adventures. My preference was for narrative flow and what happened in a game to be determined by character actions as opposed to random chance. However, I decided to alter my method, and I'm truly pleased with the outcome.

The Inspiration: Watching a Custom Mechanic

A well-known streamed game showcases a DM who regularly requests "luck rolls" from the players. He does this by selecting a type of die and defining potential outcomes tied to the result. While it's fundamentally no different from using a random table, these get invented on the spot when a character's decision doesn't have a clear conclusion.

I decided to try this approach at my own session, mostly because it seemed novel and offered a change from my standard routine. The outcome were fantastic, prompting me to reconsider the often-debated balance between pre-determination and randomization in a roleplaying game.

An Emotional Story Beat

At a session, my group had concluded a massive fight. Later, a cleric character wondered if two friendly NPCs—a sibling duo—had lived. In place of picking a fate, I asked for a roll. I instructed the player to make a twenty-sided die roll. I defined the outcomes as: on a 1-4, both died; a middling roll, only one succumbed; a high roll, they made it.

The player rolled a 4. This resulted in a profoundly poignant moment where the party found the corpses of their companions, still united in death. The group performed a ceremony, which was particularly significant due to previous roleplaying. As a parting gesture, I improvised that the remains were miraculously restored, revealing a spell-storing object. By chance, the bead's magical effect was precisely what the party needed to solve another major situation. You simply plan such perfect moments.

Sharpening Your Improvisation

This experience led me to ponder if improvisation and spontaneity are truly the beating heart of D&D. Although you are a detail-oriented DM, your improvisation muscles need exercise. Adventurers often find joy in derailing the most detailed plots. Therefore, a good DM has to be able to pivot effectively and fabricate details in the moment.

Utilizing similar mechanics is a excellent way to practice these abilities without going completely outside your preparation. The strategy is to deploy them for low-stakes situations that don't fundamentally change the session's primary direction. For instance, I would avoid using it to determine if the central plot figure is a traitor. However, I could use it to decide if the PCs enter a room right after a key action takes place.

Strengthening Shared Narrative

This technique also works to make players feel invested and foster the sensation that the game world is responsive, evolving according to their choices as they play. It prevents the sense that they are merely pawns in a rigidly planned story, thereby strengthening the shared aspect of storytelling.

This philosophy has always been part of the original design. The game's roots were reliant on random tables, which suited a playstyle focused on treasure hunting. Although contemporary D&D often prioritizes plot-driven play, leading many DMs to feel they require detailed plans, it's not necessarily the required method.

Finding the Right Balance

There is absolutely no issue with doing your prep. Yet, there is also nothing wrong with letting go and permitting the dice to decide some things in place of you. Authority is a major factor in a DM's role. We need it to facilitate play, yet we can be reluctant to release it, at times when doing so might improve the game.

My final advice is this: Have no fear of letting go of the reins. Embrace a little improvisation for inconsequential details. You might just discover that the organic story beat is infinitely more memorable than anything you could have planned by yourself.
