When I am a game master, I traditionally avoided extensive use of luck during my Dungeons & Dragons sessions. I preferred was for narrative flow and what happened in a game to be determined by player choice rather than random chance. That said, I decided to change my approach, and I'm truly glad I did.

The Catalyst: Observing a Custom Mechanic

A well-known podcast features a DM who frequently requests "chance rolls" from the players. This involves choosing a polyhedral and defining possible results based on the result. While it's fundamentally no different from rolling on a random table, these are devised on the spot when a character's decision has no predetermined conclusion.

I opted to test this method at my own table, primarily because it looked novel and presented a departure from my normal practice. The experience were remarkable, prompting me to reflect on the perennial dynamic between preparation and randomization in a D&D campaign.

A Memorable Story Beat

At a session, my party had just emerged from a city-wide battle. Afterwards, a player wondered if two beloved NPCs—a brother and sister—had lived. Instead of choosing an outcome, I asked for a roll. I told the player to make a twenty-sided die roll. I defined the outcomes as: on a 1-4, both were killed; a middling roll, only one would die; a high roll, they survived.

Fate decreed a 4. This resulted in a incredibly emotional moment where the characters found the remains of their allies, still clasped together in their final moments. The party conducted a ceremony, which was particularly significant due to earlier character interactions. As a final gesture, I decided that the forms were suddenly restored, revealing a magical Prayer Bead. I rolled for, the item's contained spell was precisely what the group required to address another major quest obstacle. One just script such perfect story beats.

Improving DM Agility

This incident made me wonder if randomization and making it up are truly the core of D&D. Although you are a meticulously planning DM, your ability to adapt can rust. Groups reliably find joy in derailing the most detailed plots. Therefore, a skilled DM needs to be able to pivot effectively and invent scenarios in the moment.

Utilizing on-the-spot randomization is a fantastic way to develop these skills without going completely outside your comfort zone. The key is to use them for small-scale situations that won't drastically alter the overarching story. As an example, I would avoid using it to decide if the main villain is a traitor. But, I might use it to figure out whether the PCs enter a room moments before a key action occurs.

Strengthening Shared Narrative

Spontaneous randomization also helps keep players engaged and foster the feeling that the adventure is responsive, evolving in reaction to their decisions as they play. It combats the sense that they are merely pawns in a rigidly planned story, thereby strengthening the collaborative aspect of the game.

Randomization has historically been embedded in the original design. Early editions were enamored with encounter generators, which made sense for a game focused on exploration. Even though modern D&D often prioritizes narrative and role-play, leading many DMs to feel they must prep extensively, that may not be the best approach.

Achieving the Right Balance

There is absolutely no problem with thorough preparation. But, equally valid no issue with relinquishing control and permitting the rolls to determine certain outcomes rather than you. Control is a big factor in a DM's role. We use it to run the game, yet we often struggle to release it, at times when doing so could be beneficial.

A piece of recommendation is this: Do not fear of letting go of control. Try a little randomness for smaller story elements. It may discover that the organic story beat is infinitely more rewarding than anything you could have pre-written on your own.
