When I am a DM, I traditionally avoided extensive use of chance during my Dungeons & Dragons games. My preference was for the plot and session development to be shaped by deliberate decisions instead of the roll of a die. Recently, I decided to try something different, and I'm truly happy with the result.

The Spark: Watching a Custom Mechanic

An influential podcast showcases a DM who often asks for "luck rolls" from the adventurers. This involves selecting a specific dice and defining possible results tied to the result. It's fundamentally no different from rolling on a random table, these get invented on the spot when a course of events doesn't have a obvious outcome.

I chose to experiment with this approach at my own game, mainly because it seemed interesting and offered a break from my usual habits. The results were fantastic, prompting me to reflect on the often-debated dynamic between preparation and spontaneity in a roleplaying game.

A Powerful Story Beat

During one session, my players had just emerged from a massive conflict. Afterwards, a cleric character inquired after two beloved NPCs—a sibling duo—had made it. Instead of picking a fate, I let the dice decide. I asked the player to make a twenty-sided die roll. I defined the outcomes as: on a 1-4, both were killed; on a 5-9, only one would die; on a 10+, they survived.

The player rolled a 4. This triggered a incredibly poignant moment where the adventurers found the remains of their companions, still clasped together in their final moments. The cleric conducted a ceremony, which was uniquely meaningful due to prior roleplaying. As a final touch, I decided that the remains were suddenly restored, containing a enchanted item. I randomized, the bead's contained spell was exactly what the group needed to resolve another critical situation. You simply orchestrate this type of serendipitous coincidences.

Sharpening Your Improvisation

This experience led me to ponder if chance and making it up are actually the core of this game. Although you are a meticulously planning DM, your skill to pivot can rust. Groups frequently take delight in derailing the best constructed plans. Therefore, a good DM needs to be able to adapt swiftly and invent content in real-time.

Using on-the-spot randomization is a fantastic way to train these skills without straying too much outside your comfort zone. The key is to deploy them for small-scale decisions that have a limited impact on the campaign's main plot. As an example, I would not employ it to decide if the king's advisor is a traitor. Instead, I could use it to decide whether the characters enter a room right after a critical event unfolds.

Strengthening Shared Narrative

This technique also serves to make players feel invested and cultivate the impression that the adventure is dynamic, shaping according to their decisions as they play. It reduces the feeling that they are merely actors in a pre-written story, thereby enhancing the shared nature of the game.

This approach has historically been integral to the original design. Original D&D were reliant on charts, which suited a game focused on treasure hunting. While contemporary D&D tends to prioritizes narrative and role-play, leading many DMs to feel they need exhaustive notes, that may not be the required method.

Striking the Right Balance

It is perfectly no issue with thorough preparation. However, there is also nothing wrong with letting go and permitting the rolls to determine certain outcomes in place of you. Direction is a major aspect of a DM's responsibilities. We require it to run the game, yet we often struggle to give some up, even when doing so could be beneficial.

The core recommendation is this: Have no fear of letting go of control. Experiment with a little randomness for inconsequential details. You might just discover that the organic story beat is significantly more rewarding than anything you could have pre-written by yourself.
