When I am a game master, I traditionally shied away from extensive use of luck during my D&D games. I tended was for narrative flow and what happened in a game to be guided by character actions rather than random chance. However, I chose to try something different, and I'm incredibly glad I did.

The Catalyst: Observing an Improvised Tool

An influential actual-play show features a DM who regularly calls for "chance rolls" from the participants. He does this by choosing a type of die and assigning potential outcomes contingent on the result. This is at its core no different from rolling on a random table, these are created in the moment when a course of events lacks a clear outcome.

I decided to try this technique at my own session, mostly because it seemed interesting and provided a change from my normal practice. The experience were fantastic, prompting me to reflect on the ongoing tension between pre-determination and improvisation in a tabletop session.

A Memorable Story Beat

At a session, my players had survived a massive conflict. Afterwards, a cleric character wondered if two friendly NPCs—a pair—had made it. 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 would perish; on a 5-9, only one would die; on a 10+, they survived.

The die came up a 4. This led to a profoundly emotional sequence where the characters found the remains of their allies, forever united in their final moments. The cleric performed last rites, which was uniquely powerful due to previous roleplaying. In a concluding touch, I improvised that the remains were miraculously transformed, revealing a enchanted item. I rolled for, the bead's contained spell was perfectly what the group lacked to resolve another critical quest obstacle. It's impossible to plan such magical moments.

Improving DM Agility

This event led me to ponder if randomization and spontaneity are in fact the essence of tabletop RPGs. Even if you are a meticulously planning DM, your skill to pivot need exercise. Players reliably take delight in ignoring the most detailed plots. Therefore, a good DM needs to be able to adapt swiftly and create content in real-time.

Utilizing on-the-spot randomization is a fantastic way to train these skills without straying too much outside your preparation. The strategy is to use them for low-stakes situations that don't fundamentally change the campaign's main plot. For instance, I wouldn't use it to establish if the central plot figure is a secret enemy. But, I might use it to figure out if the PCs arrive moments before a key action occurs.

Strengthening Player Agency

Luck rolls also serves to keep players engaged and cultivate the impression that the game world is responsive, evolving in reaction to their choices in real-time. It reduces the sense that they are merely pawns in a rigidly planned story, thereby strengthening the shared aspect of storytelling.

Randomization has always been part of the original design. Early editions were reliant on encounter generators, which made sense for a game focused on dungeon crawling. Even though modern D&D frequently emphasizes story and character, leading many DMs to feel they need exhaustive notes, this isn't always the required method.

Finding the Right Balance

It is perfectly no issue with doing your prep. Yet, it's also fine no issue with stepping back and allowing the dice to determine certain outcomes rather than you. Direction is a significant factor in a DM's role. We need it to manage the world, yet we frequently find it hard to cede it, even when doing so might improve the game.

The core suggestion is this: Do not fear of relinquishing a bit of control. Embrace a little randomness for minor details. It may create that the organic story beat is significantly more powerful than anything you would have pre-written by yourself.
