When I am a Dungeon Master, I traditionally steered clear of significant use of randomization during my Dungeons & Dragons sessions. I tended was for the plot and session development to be guided by character actions instead of random chance. However, I decided to try something different, and I'm truly glad I did.

The Spark: Watching a Custom Mechanic

A well-known podcast features a DM who regularly requests "fate rolls" from the players. He does this by choosing a type of die and defining possible results based on the roll. This is at its core no unlike rolling on a pre-generated chart, these are devised on the spot when a course of events lacks a predetermined conclusion.

I chose to experiment with this method at my own game, mainly because it looked interesting and offered a change from my standard routine. The outcome were eye-opening, prompting me to reflect on the perennial tension between pre-determination and spontaneity in a tabletop session.

An Emotional In-Game Example

In a recent session, my players had just emerged from a large-scale conflict. Later, a cleric character wondered if two beloved NPCs—a pair—had lived. Instead of choosing an outcome, I handed it over to chance. I told the player to roll a d20. I defined the outcomes as: on a 1-4, both would perish; a middling roll, a single one would die; on a 10+, they made it.

The player rolled a 4. This triggered a profoundly poignant moment where the characters came upon the bodies of their allies, forever clasped together in death. The group performed funeral rites, which was uniquely significant due to previous roleplaying. As a final gesture, I decided that the remains were suddenly transformed, revealing a magical Prayer Bead. I randomized, the item's magical effect was precisely what the group needed to address another critical quest obstacle. One just script these kinds of perfect coincidences.

Honing DM Agility

This incident caused me to question if chance and spontaneity are truly the beating heart of this game. While you are a detail-oriented DM, your ability to adapt may atrophy. Players frequently find joy in derailing the most detailed plots. Therefore, a skilled DM needs to be able to adapt swiftly and create details in the moment.

Using similar mechanics is a fantastic way to practice these abilities without straying too much outside your usual style. The strategy is to apply them for small-scale circumstances that don't fundamentally change the session's primary direction. As an example, I would avoid using it to decide if the central plot figure is a secret enemy. However, I might use it to decide if the party reach a location just in time to see a key action takes place.

Enhancing Player Agency

Luck rolls also helps make players feel invested and cultivate the impression that the adventure is alive, evolving in reaction to their decisions as they play. It combats the sense that they are merely characters in a rigidly planned narrative, thereby strengthening the collaborative foundation of the game.

This philosophy has always been embedded in the core of D&D. Original D&D were enamored with encounter generators, which made sense for a game focused on dungeon crawling. Although current D&D often prioritizes story and character, leading many DMs to feel they must prep extensively, this isn't always the best approach.

Finding the Right Balance

Absolutely no problem with being prepared. However, there is also no problem with stepping back and letting the rolls to decide some things instead of you. Authority is a big factor in a DM's responsibilities. We require it to run the game, yet we frequently find it hard to release it, at times when doing so could be beneficial.

My final advice is this: Do not fear of relinquishing a bit of your plan. Embrace a little chance for smaller details. The result could create that the organic story beat is infinitely more rewarding than anything you could have planned in advance.
