When I am a game master, I traditionally steered clear of significant use of randomization during my D&D adventures. I preferred was for narrative flow and what happened in a game to be guided by deliberate decisions as opposed to random chance. However, I opted to alter my method, and I'm very happy with the result.

The Spark: Watching an Improvised Tool

A well-known podcast utilizes a DM who frequently requests "luck rolls" from the players. He does this by picking a type of die and assigning potential outcomes contingent on the roll. This is at its core no unlike consulting a pre-generated chart, these are devised spontaneously when a player's action doesn't have a predetermined resolution.

I chose to experiment with this approach at my own game, mainly because it looked novel and presented a change from my normal practice. The results were eye-opening, prompting me to think deeply about the perennial balance between preparation and randomization in a roleplaying game.

A Memorable In-Game Example

During one session, my group had concluded a city-wide battle. When the dust settled, a player wondered if two friendly NPCs—a brother and sister—had survived. Rather than deciding myself, I handed it over to chance. I instructed the player to roll a d20. I defined the outcomes as: a low roll, both died; a middling roll, a single one would die; a high roll, they survived.

The die came up a 4. This resulted in a profoundly emotional scene where the adventurers found the corpses of their friends, forever holding hands in their final moments. The group performed a ceremony, which was uniquely meaningful due to prior roleplaying. As a parting touch, I improvised that the NPCs' bodies were strangely transformed, containing a spell-storing object. I rolled for, the item's contained spell was perfectly what the group needed to solve another major story problem. You simply plan this type of perfect story beats.

Improving Your Improvisation

This experience led me to ponder if improvisation and spontaneity are in fact the essence of D&D. While you are a prep-heavy DM, your improvisation muscles can rust. Groups often find joy in ignoring the most detailed plans. Therefore, a effective DM needs to be able to adapt swiftly and create content in real-time.

Using on-the-spot randomization is a great way to develop these abilities without straying too much outside your preparation. The trick is to apply them for minor situations that have a limited impact on the campaign's main plot. As an example, I would avoid using it to establish if the king's advisor is a traitor. However, I could use it to determine if the PCs reach a location right after a major incident occurs.

Empowering Shared Narrative

Spontaneous randomization also works to make players feel invested and create the sensation that the adventure is alive, progressing based on their choices as they play. It prevents the sense that they are merely pawns in a pre-written narrative, thereby strengthening the shared foundation of roleplaying.

Randomization has long been part of the original design. Original D&D were reliant on encounter generators, which suited a playstyle focused on treasure hunting. Although contemporary D&D frequently prioritizes plot-driven play, leading many DMs to feel they require detailed plans, that may not be the best approach.

Finding the Healthy Equilibrium

It is perfectly no issue with thorough preparation. However, there is also no problem with letting go and permitting the rolls to decide some things rather than you. Direction is a major factor in a DM's role. We need it to facilitate play, yet we can be reluctant to release it, in situations where doing so could be beneficial.

The core suggestion is this: Have no fear of letting go of control. Try a little chance for minor outcomes. You might just find that the surprising result is far more powerful than anything you could have scripted on your own.
