Chance Rolls in D&D Can Help You Be a Better DM

In my role as a game master, I traditionally shied away from significant use of luck during my D&D games. I preferred was for story direction and session development to be determined by character actions instead of the roll of a die. However, I chose to try something different, and I'm truly pleased with the outcome.

The Catalyst: Seeing an Improvised Tool

A popular streamed game utilizes a DM who often calls for "luck rolls" from the adventurers. He does this by choosing a polyhedral and defining possible results contingent on the roll. It's at its core no distinct from rolling on a pre-generated chart, these are created on the spot when a character's decision lacks a obvious conclusion.

I chose to experiment with this approach at my own session, primarily because it seemed engaging and provided a break from my standard routine. The experience were fantastic, prompting me to reconsider the perennial balance between preparation and randomization in a tabletop session.

A Powerful Session Moment

During one session, my players had just emerged from a massive conflict. Later, a cleric character asked about two friendly NPCs—a sibling duo—had survived. Rather than picking a fate, I handed it over to chance. I told the player to make a twenty-sided die roll. I defined the outcomes as: a low roll, both died; a middling roll, only one would die; on a 10+, they made it.

The die came up a 4. This resulted in a incredibly moving scene where the adventurers came upon the bodies of their allies, forever united in death. The party held funeral rites, which was especially significant due to earlier roleplaying. As a final gesture, I improvised that the NPCs' bodies were strangely restored, revealing a magical Prayer Bead. I randomized, the item's magical effect was perfectly what the group lacked to resolve another critical situation. One just orchestrate this type of magical story beats.

Sharpening Your Improvisation

This incident caused me to question if chance and making it up are truly the core of tabletop RPGs. While you are a prep-heavy DM, your skill to pivot can rust. Adventurers often excel at upending the most carefully laid plans. Therefore, a good DM has to be able to think quickly and fabricate details in the moment.

Utilizing on-the-spot randomization is a fantastic way to develop these talents without going completely outside your usual style. The strategy is to deploy them for small-scale situations that won't drastically alter the campaign's main plot. To illustrate, I would avoid using it to decide if the central plot figure is a secret enemy. Instead, I might use it to decide whether the party reach a location just in time to see a key action takes place.

Strengthening Shared Narrative

Luck rolls also helps maintain tension and create the feeling that the game world is dynamic, shaping based on their choices as they play. It combats the sense that they are merely pawns in a DM's sole narrative, thereby bolstering the collaborative nature of storytelling.

Randomization has long been embedded in the game's DNA. Early editions were reliant on random tables, which fit a game focused on dungeon crawling. Even though modern D&D tends to emphasizes plot-driven play, leading many DMs to feel they need exhaustive notes, this isn't always the best approach.

Striking the Sweet Spot

Absolutely nothing wrong with doing your prep. However, it's also fine nothing wrong with letting go and permitting the whim of chance to decide some things instead of you. Direction is a major aspect of a DM's responsibilities. We need it to facilitate play, yet we frequently find it hard to give some up, even when doing so can lead to great moments.

The core recommendation is this: Have no fear of letting go of your plan. Experiment with a little randomness for inconsequential outcomes. It may find that the unexpected outcome is far more rewarding than anything you would have pre-written on your own.
