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

In my role as a Dungeon Master, I historically shied away from heavy use of randomization during my D&D games. My preference was for narrative flow and what happened in a game to be guided by player choice instead of pure luck. That said, I opted to change my approach, and I'm very happy with the result.

The Catalyst: Seeing a Custom Mechanic

A well-known actual-play show features a DM who frequently asks for "fate rolls" from the players. The process entails choosing a specific dice and outlining possible results tied to the result. This is fundamentally no unlike using a pre-generated chart, these get invented spontaneously when a character's decision has no clear conclusion.

I decided to try this method at my own table, mostly because it looked novel and offered a departure from my normal practice. The outcome were remarkable, prompting me to reconsider the often-debated dynamic between pre-determination and improvisation in a tabletop session.

A Memorable In-Game Example

In a recent session, my party had just emerged from a massive conflict. When the dust settled, a cleric character wondered if two beloved NPCs—a sibling duo—had survived. In place of choosing an outcome, I asked for a roll. I instructed the player to make a twenty-sided die roll. I defined the outcomes as: on a 1-4, both were killed; a middling roll, a single one succumbed; a high roll, they made it.

The die came up a 4. This triggered a deeply emotional scene where the characters found the remains of their allies, still holding hands in their final moments. The party conducted funeral rites, which was uniquely meaningful due to previous story developments. In a concluding gesture, I improvised that the remains were suddenly restored, showing a magical Prayer Bead. I randomized, the bead's magical effect was perfectly what the party lacked to solve another pressing story problem. You simply script this type of perfect story beats.

Honing DM Agility

This experience caused me to question if chance and thinking on your feet are actually the beating heart of tabletop RPGs. Although you are a detail-oriented DM, your skill to pivot can rust. Adventurers frequently excel at upending the best constructed plans. Therefore, a good DM needs to be able to pivot effectively and create scenarios on the fly.

Using similar mechanics is a excellent way to practice these skills without straying too much outside your preparation. The key is to use them for low-stakes circumstances that have a limited impact on the overarching story. To illustrate, I would not employ it to determine if the king's advisor is a secret enemy. However, I would consider using it to decide whether the characters reach a location right after a key action occurs.

Empowering Shared Narrative

Luck rolls also helps maintain tension and create the sensation that the game world is responsive, evolving according to their decisions immediately. It prevents the perception that they are merely characters in a rigidly planned narrative, thereby enhancing the cooperative nature of storytelling.

This approach has historically been part of the game's DNA. Original D&D were filled with charts, which made sense for a playstyle focused on treasure hunting. Although modern D&D tends to emphasizes story and character, leading many DMs to feel they need exhaustive notes, that may not be the required method.

Achieving the Sweet Spot

It is perfectly no problem with thorough preparation. However, equally valid no problem with stepping back and permitting the whim of chance to guide minor details instead of you. Direction is a significant factor in a DM's role. We use it to manage the world, yet we frequently find it hard to cede it, in situations where doing so could be beneficial.

The core recommendation is this: Don't be afraid of relinquishing a bit of your plan. Embrace a little randomness for inconsequential story elements. The result could create that the organic story beat is far more rewarding than anything you could have pre-written in advance.
