Chance Rolls in D&D May Assist You Become a More Effective Dungeon Master

When I am a DM, I historically shied away from significant use of luck during my D&D adventures. I preferred was for story direction and session development to be shaped by deliberate decisions as opposed to the roll of a die. However, I chose to alter my method, and I'm truly happy with the result.

The Inspiration: Seeing an Improvised Tool

An influential podcast features a DM who frequently calls for "chance rolls" from the adventurers. This involves choosing a polyhedral and defining potential outcomes based on the result. While it's essentially no different from consulting a random table, these get invented in the moment when a player's action has no clear conclusion.

I chose to experiment with this method at my own game, mostly because it looked interesting and provided a change from my normal practice. The results were remarkable, prompting me to reflect on the often-debated tension between preparation and improvisation in a roleplaying game.

An Emotional In-Game Example

At a session, my party had concluded a massive battle. Later, a player asked about two beloved NPCs—a brother and sister—had lived. In place of picking a fate, I handed it over to chance. I instructed the player to make a twenty-sided die roll. The stakes were: on a 1-4, both died; on a 5-9, a single one succumbed; on a 10+, they both lived.

Fate decreed a 4. This triggered a profoundly moving scene where the adventurers found the remains of their companions, still united in death. The group conducted last rites, which was particularly meaningful due to prior character interactions. As a final gesture, I chose that the remains were suddenly restored, showing a spell-storing object. By chance, the item's contained spell was exactly what the group needed to solve another pressing quest obstacle. One just orchestrate this type of serendipitous moments.

Honing Your Improvisation

This incident made me wonder if randomization and spontaneity are in fact the core of tabletop RPGs. Although you are a detail-oriented DM, your skill to pivot can rust. Groups frequently take delight in upending the most detailed plans. Therefore, a effective DM needs to be able to think quickly and fabricate scenarios in real-time.

Employing luck rolls is a fantastic way to practice these talents without venturing too far outside your comfort zone. The key is to use them for small-scale decisions that have a limited impact on the session's primary direction. As an example, I would avoid using it to decide if the central plot figure is a secret enemy. But, I could use it to decide whether the characters reach a location right after a major incident takes place.

Empowering Shared Narrative

This technique also helps maintain tension and create the sensation that the adventure is responsive, progressing in reaction to their choices immediately. It combats the sense that they are merely pawns in a rigidly planned script, thereby bolstering the cooperative foundation of the game.

This approach has historically been part of the game's DNA. The game's roots were filled with random tables, which fit a game focused on exploration. Even though contemporary D&D tends to emphasizes story and character, leading many DMs to feel they need exhaustive notes, it's not necessarily the best approach.

Striking the Right Balance

Absolutely nothing wrong with doing your prep. Yet, there is also no problem with letting go and permitting the dice to determine certain outcomes in place of you. Control is a major part of a DM's job. We require it to manage the world, yet we frequently find it hard to cede it, in situations where doing so might improve the game.

The core recommendation is this: Have no fear of letting go of your plan. Embrace a little improvisation for inconsequential details. The result could find that the surprising result is infinitely more rewarding than anything you might have planned by yourself.
