In my role as a game master, I traditionally shied away from heavy use of randomization during my tabletop roleplaying adventures. I tended was for the plot and what happened in a game to be guided by character actions rather than random chance. However, I decided to alter my method, and I'm incredibly glad I did.

The Spark: Seeing a Custom Mechanic

A popular podcast features a DM who regularly asks for "fate rolls" from the participants. He does this by selecting a polyhedral and outlining possible results tied to the result. This is at its core no unlike consulting a pre-generated chart, these are created in the moment when a character's decision has no obvious outcome.

I chose to experiment with this technique at my own game, mainly because it seemed novel and provided a departure from my standard routine. The experience were remarkable, prompting me to reflect on the perennial dynamic between planning and spontaneity in a D&D campaign.

An Emotional Session Moment

In a recent session, my group had concluded a large-scale conflict. When the dust settled, a cleric character wondered if two key NPCs—a brother and sister—had lived. Rather than deciding myself, I let the dice decide. I asked the player to make a twenty-sided die roll. The possible results were: a low roll, both died; a middling roll, only one succumbed; a high roll, they made it.

The player rolled a 4. This led to a profoundly emotional scene where the adventurers discovered the bodies of their friends, forever holding hands in death. The party held funeral rites, which was particularly meaningful due to previous story developments. As a final gesture, I decided that the forms were miraculously restored, containing a magical Prayer Bead. I randomized, the bead's contained spell was precisely what the party needed to address another critical story problem. It's impossible to script these kinds of serendipitous moments.

Sharpening On-the-Spot Skills

This incident caused me to question if chance and spontaneity are in fact the core of tabletop RPGs. Even if you are a meticulously planning DM, your ability to adapt can rust. Groups frequently excel at upending the most detailed narratives. Therefore, a skilled DM must be able to adapt swiftly and invent details in the moment.

Utilizing on-the-spot randomization is a fantastic way to practice these talents without going completely outside your preparation. The key is to use them for minor decisions that don't fundamentally change the session's primary direction. As an example, I would avoid using it to establish if the king's advisor is a traitor. However, I might use it to determine if the party reach a location just in time to see a key action occurs.

Enhancing Collaborative Storytelling

Luck rolls also works to make players feel invested and foster the sensation that the game world is responsive, shaping based on their choices as they play. It reduces the perception that they are merely characters in a DM's sole narrative, thereby enhancing the cooperative aspect of storytelling.

This philosophy has always been part of the core of D&D. The game's roots were filled with encounter generators, which fit a playstyle focused on exploration. While current D&D frequently focuses on plot-driven play, leading many DMs to feel they need exhaustive notes, that may not be the required method.

Finding the Right Balance

There is absolutely nothing wrong with doing your prep. However, there is also nothing wrong with relinquishing control and allowing the dice to guide minor details instead of you. Direction is a major factor in a DM's job. We need it to facilitate play, yet we often struggle to cede it, even when doing so can lead to great moments.

My final recommendation is this: Do not fear of relinquishing a bit of your plan. Try a little randomness for inconsequential story elements. It may create that the unexpected outcome is far more memorable than anything you could have pre-written in advance.
