When I am a DM, I historically avoided significant use of chance during my Dungeons & Dragons adventures. I tended was for narrative flow and session development to be determined by deliberate decisions rather than pure luck. However, I opted to alter my method, and I'm very pleased with the outcome.

The Catalyst: Observing a Custom Mechanic

A well-known actual-play show showcases a DM who regularly calls for "chance rolls" from the participants. The process entails selecting a polyhedral and assigning consequences based on the number. This is essentially no different from rolling on a pre-generated chart, these are devised in the moment when a course of events lacks a clear outcome.

I opted to test this approach at my own game, mostly because it looked interesting and provided a departure from my usual habits. The outcome were remarkable, prompting me to reflect on the perennial tension between planning and improvisation in a D&D campaign.

An Emotional Session Moment

At a session, my players had concluded a massive fight. When the dust settled, a player asked about two beloved NPCs—a sibling duo—had survived. Rather than deciding myself, I asked for a roll. I asked the player to roll a d20. The possible results were: a low roll, both would perish; on a 5-9, a single one succumbed; a high roll, they made it.

The player rolled a 4. This led to a incredibly emotional sequence where the adventurers found the remains of their allies, still clasped together in their final moments. The party held a ceremony, which was particularly meaningful due to prior story developments. In a concluding reward, I chose that the NPCs' bodies were strangely restored, showing a enchanted item. I rolled for, the bead's contained spell was precisely what the party needed to address another critical situation. One just plan this type of perfect story beats.

Improving Your Improvisation

This experience made me wonder if chance and thinking on your feet are truly the essence of this game. Although you are a detail-oriented DM, your improvisation muscles need exercise. Groups often find joy in derailing the best constructed narratives. Therefore, a effective DM must be able to pivot effectively and fabricate scenarios on the fly.

Utilizing on-the-spot randomization is a excellent way to train these abilities without straying too much outside your comfort zone. The trick is to apply them for small-scale circumstances that won't drastically alter the session's primary direction. To illustrate, I wouldn't use it to establish if the king's advisor is a traitor. Instead, I would consider using it to determine whether the party enter a room moments before a major incident unfolds.

Empowering Player Agency

Spontaneous randomization also helps maintain tension and create the feeling that the adventure is dynamic, shaping in reaction to their choices as they play. It prevents the sense that they are merely pawns in a DM's sole story, thereby bolstering the shared nature of the game.

Randomization has historically been part of the game's DNA. Original D&D were filled with encounter generators, which suited a game focused on dungeon crawling. While current D&D frequently emphasizes plot-driven play, leading many DMs to feel they need exhaustive notes, that may not be the best approach.

Achieving the Right Balance

It is perfectly nothing wrong with doing your prep. But, it's also fine no problem with letting go and permitting the whim of chance to determine certain outcomes rather than you. Authority is a major aspect of a DM's job. We require it to run the game, yet we frequently find it hard to cede it, even when doing so can lead to great moments.

A piece of advice is this: Don't be afraid of temporarily losing control. Experiment with a little randomness for inconsequential story elements. The result could discover that the unexpected outcome is far more rewarding than anything you might have pre-written by yourself.
