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

When I am a game master, I usually avoided heavy use of luck during my D&D adventures. I tended was for story direction and session development to be shaped by player choice as opposed to the roll of a die. Recently, I chose to change my approach, and I'm truly glad I did.

The Catalyst: Seeing 'Luck Rolls'

An influential streamed game features a DM who often asks for "chance rolls" from the adventurers. The process entails choosing a type of die and defining potential outcomes tied to the number. While it's at its core no different from using a pre-generated chart, these are created on the spot when a course of events doesn't have a clear resolution.

I decided to try this approach at my own game, primarily because it looked novel and provided a departure from my usual habits. The experience were remarkable, prompting me to reflect on the ongoing dynamic between pre-determination and improvisation in a D&D campaign.

A Powerful In-Game Example

At a session, my group had concluded a large-scale fight. Later, a cleric character inquired after two friendly NPCs—a pair—had made it. In place of choosing an outcome, I asked for a roll. I told the player to roll a d20. The possible results were: a low roll, both would perish; on a 5-9, a single one would die; a high roll, they made it.

Fate decreed a 4. This resulted in a deeply moving scene where the party came upon the corpses of their friends, still clasped together in death. The group performed funeral rites, which was especially meaningful due to previous story developments. In a concluding reward, I chose that the NPCs' bodies were suddenly transformed, revealing a enchanted item. By chance, the item's contained spell was precisely what the party lacked to resolve another major quest obstacle. It's impossible to script these kinds of magical coincidences.

Honing DM Agility

This event caused me to question if improvisation and making it up are actually the essence of tabletop RPGs. Although you are a meticulously planning DM, your improvisation muscles can rust. Groups often find joy in ignoring the best constructed plots. Therefore, a good DM has to be able to think quickly and invent scenarios in the moment.

Utilizing on-the-spot randomization is a excellent way to develop these abilities without straying too much outside your usual style. The strategy is to use them for low-stakes decisions that won't drastically alter the session's primary direction. As an example, I would avoid using it to determine if the central plot figure is a traitor. However, I might use it to determine if the characters arrive right after a critical event unfolds.

Enhancing Collaborative Storytelling

This technique also helps maintain tension and cultivate the impression that the adventure is alive, progressing based on their decisions as they play. It reduces the feeling that they are merely characters in a rigidly planned story, thereby bolstering the collaborative foundation of roleplaying.

Randomization has always been embedded in the original design. The game's roots were enamored with random tables, which fit a game focused on dungeon crawling. Even though contemporary D&D frequently focuses on narrative and role-play, leading many DMs to feel they need exhaustive notes, that may not be the best approach.

Achieving the Sweet Spot

Absolutely no problem with being prepared. Yet, it's also fine no problem with stepping back and allowing the whim of chance to decide some things in place of you. Direction is a significant aspect of a DM's role. We require it to run the game, yet we frequently find it hard to give some up, even when doing so might improve the game.

My final advice is this: Do not fear of letting go of control. Experiment with a little improvisation for smaller outcomes. The result could find that the surprising result is far more rewarding than anything you would have scripted on your own.
