Chance Rolls in Dungeons & Dragons Can Help You Become a Superior Dungeon Master

In my role as a game master, I historically avoided heavy use of chance during my tabletop roleplaying adventures. I tended was for story direction and what happened in a game to be shaped by character actions instead of the roll of a die. Recently, I chose to try something different, and I'm incredibly happy with the result.

The Spark: Seeing 'Luck Rolls'

A well-known streamed game showcases a DM who regularly requests "fate rolls" from the players. This involves picking a type of die and assigning consequences tied to the roll. It's essentially no different from consulting a pre-generated chart, these get invented on the spot when a player's action doesn't have a obvious conclusion.

I chose to experiment with this technique at my own table, mostly because it looked interesting and offered a break from my usual habits. The experience were fantastic, prompting me to reconsider the ongoing tension between pre-determination and spontaneity in a D&D campaign.

A Memorable In-Game Example

At a session, my group had just emerged from a massive fight. When the dust settled, a cleric character asked about two friendly NPCs—a brother and sister—had lived. Rather than choosing an outcome, I asked for a roll. 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; on a 10+, they survived.

The player rolled a 4. This triggered a deeply moving sequence where the characters discovered the corpses of their allies, forever clasped together in their final moments. The party conducted a ceremony, which was uniquely powerful due to earlier roleplaying. As a final touch, I chose that the NPCs' bodies were suddenly transformed, showing a spell-storing object. By chance, the item's magical effect was precisely what the group lacked to solve another critical story problem. It's impossible to orchestrate these kinds of perfect coincidences.

Honing On-the-Spot Skills

This event led me to ponder if chance and thinking on your feet are actually the core of tabletop RPGs. While you are a prep-heavy DM, your skill to pivot may atrophy. Groups frequently excel at derailing the most detailed narratives. Therefore, a skilled DM has to be able to think quickly and fabricate details on the fly.

Using luck rolls is a great way to practice these skills without going completely outside your comfort zone. The trick is to deploy them for minor decisions that don't fundamentally change the campaign's main plot. As an example, I would not employ it to establish if the main villain is a secret enemy. However, I might use it to determine whether the party arrive just in time to see a key action takes place.

Enhancing Player Agency

Luck rolls also helps make players feel invested and cultivate the impression that the game world is dynamic, shaping according to their decisions as they play. It combats the sense that they are merely characters in a rigidly planned story, thereby enhancing the shared nature of the game.

Randomization has long been part of the original design. Early editions were enamored with random tables, which suited a game focused on exploration. While contemporary D&D often focuses on story and character, leading many DMs to feel they must prep extensively, that may not be the best approach.

Striking the Right Balance

It is perfectly no problem with being prepared. However, there is also no issue with stepping back and permitting the whim of chance to determine certain outcomes instead of you. Direction is a major factor in a DM's job. We need it to manage the world, yet we can be reluctant to release it, at times when doing so might improve the game.

The core suggestion is this: Do not fear of relinquishing a bit of the reins. Embrace a little improvisation for inconsequential story elements. It may create that the surprising result is infinitely more memorable than anything you might have planned on your own.
