Chance Rolls in Dungeons & Dragons Can Help You Become a More Effective DM

As a Dungeon Master, I historically steered clear of heavy use of randomization during my D&D adventures. My preference was for the plot and what happened in a game to be guided by deliberate decisions instead of random chance. However, I chose to change my approach, and I'm truly happy with the result.

The Spark: Seeing 'Luck Rolls'

An influential streamed game showcases a DM who often asks for "fate rolls" from the participants. The process entails selecting a polyhedral and defining possible results tied to the result. It's essentially no unlike using a random table, these are created on the spot when a character's decision lacks a clear resolution.

I decided to try this approach at my own session, mostly because it seemed interesting and presented a break from my normal practice. The experience were eye-opening, prompting me to reconsider the perennial tension between pre-determination and randomization in a roleplaying game.

A Memorable Session Moment

At a session, my party had concluded a large-scale fight. When the dust settled, a cleric character asked about two friendly NPCs—a pair—had survived. In place of choosing an outcome, I asked for a roll. I asked the player to roll a d20. The stakes were: a low roll, both died; a middling roll, a single one succumbed; on a 10+, they both lived.

The die came up a 4. This triggered a incredibly emotional sequence where the party found the corpses of their friends, forever united in death. The group performed funeral rites, which was uniquely powerful due to previous story developments. As a parting touch, I decided that the remains were suddenly transformed, containing a magical Prayer Bead. By chance, the bead's magical effect was exactly what the party required to resolve another critical situation. You simply script such serendipitous story beats.

Sharpening On-the-Spot Skills

This event caused me to question if chance and spontaneity are truly the beating heart of tabletop RPGs. While you are a detail-oriented DM, your ability to adapt can rust. Groups frequently take delight in ignoring the most detailed plots. Therefore, a skilled DM needs to be able to pivot effectively and invent scenarios on the fly.

Utilizing on-the-spot randomization is a excellent way to develop these talents without straying too much outside your comfort zone. The trick is to use them for minor situations that don't fundamentally change the campaign's main plot. For instance, I wouldn't use it to establish if the main villain is a traitor. But, I would consider using it to determine whether the party arrive right after a critical event unfolds.

Empowering Shared Narrative

This technique also serves to make players feel invested and create the sensation that the game world is alive, progressing based on their decisions immediately. It combats the perception that they are merely characters in a DM's sole story, thereby enhancing the collaborative nature of storytelling.

This approach has always been integral to the original design. Early editions were enamored with random tables, which fit a game focused on exploration. Although current D&D frequently prioritizes story and character, leading many DMs to feel they must prep extensively, this isn't always the best approach.

Striking the Sweet Spot

It is perfectly nothing wrong with doing your prep. But, equally valid no problem with stepping back and permitting the whim of chance to determine certain outcomes rather than you. Control is a major factor in a DM's job. We use it to manage the world, yet we frequently find it hard to release it, in situations where doing so might improve the game.

A piece of suggestion is this: Don't be afraid of letting go of your plan. Embrace a little randomness for minor story elements. It may find that the surprising result is infinitely more powerful than anything you might have scripted by yourself.
