In my role as a game master, I traditionally shied away from significant use of chance during my Dungeons & Dragons adventures. I preferred was for the plot and session development to be guided by player choice instead of the roll of a die. Recently, I opted to change my approach, and I'm incredibly glad I did.

The Spark: Seeing a Custom Mechanic

A popular actual-play show showcases a DM who regularly asks for "luck rolls" from the adventurers. This involves picking a specific dice and defining possible results contingent on the result. While it's at its core no different from rolling on a pre-generated chart, these are devised spontaneously when a character's decision has no clear conclusion.

I opted to test this technique at my own table, primarily because it looked novel and presented a change from my usual habits. The experience were fantastic, prompting me to reconsider the ongoing balance between preparation and randomization in a roleplaying game.

A Powerful In-Game Example

During one session, my group had just emerged from a massive fight. When the dust settled, a cleric character asked about two beloved NPCs—a sibling duo—had lived. Rather than picking a fate, I let the dice decide. I asked the player to make a twenty-sided die roll. The possible results were: on a 1-4, both would perish; a middling roll, only one succumbed; on a 10+, they made it.

Fate decreed a 4. This led to a deeply emotional scene where the adventurers found the corpses of their friends, forever united in their final moments. The party performed a ceremony, which was particularly powerful due to prior character interactions. As a final gesture, I decided that the remains were suddenly transformed, containing a spell-storing object. I randomized, the item's contained spell was perfectly what the party required to address another pressing quest obstacle. One just plan such perfect story beats.

Sharpening DM Agility

This event led me to ponder if improvisation and thinking on your feet are actually the essence of this game. Although you are a meticulously planning DM, your skill to pivot may atrophy. Groups frequently excel at derailing the most detailed narratives. Therefore, a good DM needs to be able to think quickly and fabricate scenarios in the moment.

Utilizing similar mechanics is a excellent way to develop these talents without venturing too far outside your preparation. The trick is to use them for low-stakes circumstances that don't fundamentally change the campaign's main plot. For instance, I would avoid using it to decide if the main villain is a traitor. Instead, I could use it to determine if the characters enter a room just in time to see a major incident takes place.

Strengthening Shared Narrative

Spontaneous randomization also helps make players feel invested and create the sensation that the adventure is dynamic, evolving according to their decisions immediately. It prevents the sense that they are merely characters in a pre-written story, thereby enhancing the cooperative aspect of roleplaying.

This approach has long been embedded in the core of D&D. The game's roots were filled with charts, which suited a playstyle focused on exploration. Even though contemporary D&D frequently focuses on narrative and role-play, leading many DMs to feel they must prep extensively, it's not necessarily the only path.

Finding the Healthy Equilibrium

There is absolutely no issue with being prepared. Yet, there is also no issue with stepping back and permitting the dice to guide minor details in place of you. Control is a major aspect of a DM's role. We use it to facilitate play, yet we frequently find it hard to give some up, at times when doing so might improve the game.

A piece of suggestion is this: Do not fear of letting go of your plan. Try a little randomness for inconsequential outcomes. The result could discover that the unexpected outcome is far more memorable than anything you could have scripted in advance.
