As a DM, I usually avoided significant use of chance during my Dungeons & Dragons sessions. My preference was for narrative flow and what happened in a game to be shaped by player choice rather than the roll of a die. That said, I decided to try something different, and I'm truly glad I did.

The Spark: Observing a Custom Mechanic

A popular podcast showcases a DM who frequently requests "luck rolls" from the participants. This involves picking a specific dice and assigning potential outcomes based on the number. It's fundamentally no unlike rolling on a random table, these get invented in the moment when a course of events lacks a obvious resolution.

I chose to experiment with this technique at my own session, primarily because it seemed engaging and presented a departure from my standard routine. The results were fantastic, prompting me to reflect on the ongoing balance between pre-determination and spontaneity in a D&D campaign.

An Emotional Story Beat

During one session, my players had concluded a large-scale fight. Afterwards, a cleric character wondered if two friendly NPCs—a pair—had survived. Instead of deciding myself, I let the dice decide. I asked the player to roll a d20. I defined the outcomes as: a low roll, both died; a middling roll, a single one would die; on a 10+, they survived.

Fate decreed a 4. This led to a profoundly poignant moment where the party discovered the bodies of their friends, still clasped together in death. The cleric conducted a ceremony, which was particularly meaningful due to prior story developments. As a parting touch, I chose that the remains were strangely restored, containing a spell-storing object. By chance, the bead's magical effect was perfectly what the party required to solve another pressing story problem. It's impossible to script such serendipitous moments.

Sharpening Your Improvisation

This incident caused me to question if improvisation and spontaneity are in fact the core of D&D. Although you are a detail-oriented DM, your improvisation muscles can rust. Adventurers frequently take delight in derailing the most detailed plans. Therefore, a effective DM needs to be able to think quickly and fabricate details in the moment.

Using luck rolls is a great way to practice these skills without venturing too far outside your preparation. The strategy is to apply them for minor circumstances that have a limited impact on the session's primary direction. As an example, I would not employ it to determine if the king's advisor is a secret enemy. But, I might use it to decide whether the characters reach a location just in time to see a key action unfolds.

Empowering Collaborative Storytelling

This technique also serves to maintain tension and cultivate the impression that the story is alive, shaping according to their decisions immediately. It prevents the feeling that they are merely characters in a rigidly planned narrative, thereby strengthening the collaborative foundation of storytelling.

This philosophy has long been embedded in the game's DNA. The game's roots were reliant on encounter generators, which suited a game focused on treasure hunting. Even though contemporary D&D frequently emphasizes narrative and role-play, leading many DMs to feel they require detailed plans, that may not be the only path.

Finding the Sweet Spot

It is perfectly no issue with thorough preparation. But, equally valid no issue with relinquishing control and permitting the rolls to decide some things instead of you. Direction is a big part of a DM's responsibilities. We use it to run the game, yet we often struggle to give some up, at times when doing so might improve the game.

My final advice is this: Do not fear of letting go of control. Try a little randomness for minor details. You might just create that the organic story beat is far more rewarding than anything you might have pre-written on your own.
