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

As a Dungeon Master, I traditionally avoided significant use of luck during my tabletop roleplaying games. I preferred was for narrative flow and what happened in a game to be guided by player choice instead of the roll of a die. That said, I chose to alter my method, and I'm truly happy with the result.

The Catalyst: Watching 'Luck Rolls'

A popular podcast showcases a DM who often asks for "luck rolls" from the adventurers. He does this by picking a specific dice and assigning possible results tied to the roll. While it's essentially no unlike rolling on a pre-generated chart, these are devised on the spot when a character's decision has no predetermined conclusion.

I chose to experiment with this approach at my own table, mostly because it looked interesting and provided a break from my normal practice. The results were eye-opening, prompting me to think deeply about the often-debated dynamic between pre-determination and improvisation in a D&D campaign.

A Memorable Session Moment

During one session, my group had survived a massive fight. Afterwards, a player wondered if two key NPCs—a pair—had made it. Rather than deciding myself, I handed it over to chance. I told the player to make a twenty-sided die roll. The possible results were: on a 1-4, both would perish; on a 5-9, a single one succumbed; a high roll, they made it.

The player rolled a 4. This triggered a incredibly poignant scene where the party found the bodies of their friends, still clasped together in their final moments. The cleric held funeral rites, which was particularly significant due to previous story developments. As a parting touch, I decided that the forms were miraculously restored, containing a enchanted item. By chance, the item's magical effect was precisely what the group needed to solve another major quest obstacle. It's impossible to script this type of magical coincidences.

Sharpening On-the-Spot Skills

This event made me wonder if improvisation and spontaneity are actually the core of tabletop RPGs. Even if you are a meticulously planning DM, your skill to pivot can rust. Groups frequently excel at upending the most carefully laid plots. Therefore, a skilled DM must be able to pivot effectively and invent content in real-time.

Utilizing on-the-spot randomization is a great way to practice these abilities without venturing too far outside your comfort zone. The trick is to use them for low-stakes situations that won't drastically alter the overarching story. To illustrate, I would avoid using it to determine if the central plot figure is a secret enemy. But, I might use it to figure out whether the party reach a location just in time to see a critical event occurs.

Empowering Shared Narrative

Spontaneous randomization also works to maintain tension and cultivate the feeling that the adventure is dynamic, evolving according to their actions in real-time. It reduces the sense that they are merely characters in a pre-written script, thereby bolstering the cooperative aspect of the game.

This philosophy has historically been embedded in the original design. Original D&D were enamored with encounter generators, which made sense for a playstyle focused on treasure hunting. Even though current D&D often emphasizes story and character, leading many DMs to feel they require detailed plans, it's not necessarily the best approach.

Striking the Healthy Equilibrium

Absolutely nothing wrong with being prepared. However, there is also no problem with stepping back and allowing the whim of chance to determine certain outcomes rather than you. Authority is a big factor in a DM's responsibilities. We require it to manage the world, yet we can be reluctant to cede it, even when doing so could be beneficial.

The core recommendation is this: Do not fear of letting go of the reins. Try a little improvisation for inconsequential outcomes. You might just create that the organic story beat is far more powerful than anything you could have scripted in advance.
