In my role as a game master, I historically shied away from heavy use of randomization during my tabletop roleplaying adventures. I preferred was for narrative flow and what happened in a game to be determined by player choice instead of pure luck. However, I opted to try something different, and I'm truly pleased with the outcome.

The Inspiration: Watching a Custom Mechanic

An influential actual-play show features a DM who often asks for "chance rolls" from the players. The process entails selecting a polyhedral and assigning possible results contingent on the number. It's essentially no distinct from consulting a pre-generated chart, these are created on the spot when a player's action doesn't have a obvious conclusion.

I chose to experiment with this technique at my own table, mainly because it looked engaging and provided a break from my usual habits. The results were remarkable, prompting me to reconsider the ongoing dynamic between planning and randomization in a tabletop session.

A Memorable In-Game Example

In a recent session, my group had concluded a city-wide battle. Later, a cleric character asked about two beloved NPCs—a pair—had survived. Instead of picking a fate, I let the dice decide. I told the player to make a twenty-sided die roll. The stakes were: a low roll, both were killed; on a 5-9, a single one would die; a high roll, they survived.

Fate decreed a 4. This resulted in a profoundly emotional moment where the party found the remains of their friends, still clasped together in their final moments. The cleric conducted a ceremony, which was uniquely powerful due to prior roleplaying. In a concluding gesture, I chose that the NPCs' bodies were miraculously restored, revealing a spell-storing object. I randomized, the item's magical effect was precisely what the party needed to solve another pressing story problem. One just script this type of magical coincidences.

Sharpening DM Agility

This experience caused me to question if randomization and thinking on your feet are actually the core of tabletop RPGs. While you are a meticulously planning DM, your ability to adapt need exercise. Groups often excel at upending the most carefully laid plans. Therefore, a good DM must be able to pivot effectively and invent scenarios in real-time.

Employing similar mechanics is a fantastic way to practice these skills without going completely outside your preparation. The key is to use them for minor situations that don't fundamentally change the session's primary direction. For instance, I wouldn't use it to determine if the king's advisor is a secret enemy. But, I might use it to figure out whether the PCs enter a room right after a critical event takes place.

Enhancing Player Agency

This technique also works to keep players engaged and create the sensation that the story is dynamic, shaping in reaction to their choices immediately. It reduces the sense that they are merely pawns in a rigidly planned story, thereby strengthening the shared nature of the game.

This philosophy has historically been integral to the game's DNA. The game's roots were filled with random tables, which fit a game focused on treasure hunting. Although contemporary D&D frequently emphasizes narrative and role-play, leading many DMs to feel they need exhaustive notes, that may not be the required method.

Finding the Sweet Spot

There is absolutely no issue with doing your prep. Yet, it's also fine no problem with letting go and letting the whim of chance to guide minor details instead of you. Authority is a big aspect of a DM's job. We use it to facilitate play, yet we often struggle to give some up, even when doing so can lead to great moments.

A piece of suggestion is this: Have no fear of letting go of the reins. Experiment with a little improvisation for smaller outcomes. You might just find that the unexpected outcome is infinitely more rewarding than anything you would have planned by yourself.
