Luck Rolls in D&D May Assist You Become a More Effective DM

In my role as a DM, I usually shied away from heavy use of randomization during my tabletop roleplaying games. I tended was for the plot and what happened in a game to be determined by character actions rather than pure luck. However, I decided to alter my method, and I'm very pleased with the outcome.

The Catalyst: Watching an Improvised Tool

An influential actual-play show utilizes a DM who often calls for "luck rolls" from the adventurers. He does this by choosing a type of die and assigning potential outcomes tied to the result. While it's essentially no unlike rolling on a pre-generated chart, these get invented spontaneously when a character's decision doesn't have a predetermined conclusion.

I decided to try this approach at my own game, mostly because it appeared novel and presented a change from my usual habits. The outcome were fantastic, prompting me to reflect on the ongoing balance between planning and improvisation in a tabletop session.

A Memorable Story Beat

At a session, my players had concluded a city-wide conflict. Afterwards, a player asked about two key NPCs—a pair—had survived. In place of choosing an outcome, I asked for a roll. I asked the player to roll a d20. The stakes were: on a 1-4, both died; a middling roll, only one succumbed; a high roll, they both lived.

The player rolled a 4. This led to a deeply emotional moment where the adventurers found the corpses of their companions, still clasped together in death. The cleric performed funeral rites, which was uniquely powerful due to prior character interactions. As a final gesture, I chose that the NPCs' bodies were strangely restored, revealing a spell-storing object. I randomized, the bead's magical effect was exactly what the group required to solve another major story problem. You simply orchestrate this type of perfect coincidences.

Honing Your Improvisation

This experience led me to ponder if randomization and spontaneity are in fact the beating heart of tabletop RPGs. Even if you are a detail-oriented DM, your improvisation muscles need exercise. Players frequently find joy in derailing the most detailed narratives. Therefore, a good DM has to be able to pivot effectively and invent scenarios in the moment.

Employing similar mechanics is a fantastic way to practice these skills without venturing too far outside your comfort zone. The key is to apply them for small-scale circumstances that won't drastically alter the overarching story. For instance, I would avoid using it to decide if the main villain is a secret enemy. But, I could use it to decide whether the characters arrive just in time to see a key action unfolds.

Strengthening Collaborative Storytelling

Luck rolls also helps maintain tension and foster the feeling that the story is dynamic, evolving according to their decisions as they play. It prevents the sense that they are merely characters in a DM's sole script, thereby strengthening the cooperative nature of the game.

This approach has historically been part of the original design. The game's roots were filled with charts, which made sense for a playstyle focused on treasure hunting. While modern D&D often focuses on plot-driven play, leading many DMs to feel they require detailed plans, it's not necessarily the best approach.

Finding the Healthy Equilibrium

Absolutely no problem with doing your prep. However, it's also fine no problem with letting go and letting the whim of chance to guide minor details rather than you. Direction is a major aspect of a DM's role. We require it to facilitate play, yet we can be reluctant to give some up, at times when doing so could be beneficial.

A piece of recommendation is this: Don't be afraid of letting go of control. Embrace a little improvisation for smaller outcomes. It may find that the unexpected outcome is infinitely more powerful than anything you could have scripted on your own.
