As a DM, I historically steered clear of heavy use of chance during my tabletop roleplaying games. I tended was for story direction and what happened in a game to be determined by deliberate decisions rather than the roll of a die. Recently, I chose to alter my method, and I'm incredibly happy with the result.

The Spark: Watching an Improvised Tool

An influential podcast showcases a DM who frequently asks for "chance rolls" from the participants. He does this by selecting a specific dice and assigning possible results tied to the number. It's fundamentally no distinct from consulting a pre-generated chart, these get invented spontaneously when a player's action has no obvious outcome.

I opted to test this approach at my own game, mainly because it seemed interesting and presented a break from my standard routine. The outcome were eye-opening, prompting me to reflect on the ongoing dynamic between preparation and spontaneity in a tabletop session.

A Memorable In-Game Example

In a recent session, my group had survived a massive battle. Later, a player inquired after two friendly NPCs—a pair—had survived. Rather than picking a fate, 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 succumbed; a high roll, they both lived.

Fate decreed a 4. This resulted in a deeply moving moment where the characters came upon the remains of their friends, forever clasped together in death. The cleric conducted a ceremony, which was particularly powerful due to previous character interactions. As a final reward, I chose that the remains were miraculously transformed, containing a spell-storing object. I randomized, the item's contained spell was exactly what the group lacked to solve another major situation. One just plan these kinds of magical story beats.

Sharpening DM Agility

This experience caused me to question if randomization and thinking on your feet are in fact the essence of tabletop RPGs. Even if you are a prep-heavy DM, your skill to pivot need exercise. Adventurers frequently find joy in upending the best constructed plots. Therefore, a effective DM needs to be able to adapt swiftly and create scenarios in the moment.

Using on-the-spot randomization is a excellent way to train these abilities without going completely outside your preparation. The key is to use them for small-scale decisions that have a limited impact on the overarching story. For instance, I wouldn't use it to establish if the king's advisor is a traitor. But, I might use it to determine whether the PCs reach a location just in time to see a critical event occurs.

Empowering Collaborative Storytelling

This technique also works to keep players engaged and create the sensation that the game world is dynamic, progressing based on their actions immediately. It prevents the sense that they are merely actors in a pre-written narrative, thereby bolstering the shared aspect of the game.

This philosophy has long been embedded in the game's DNA. The game's roots were filled with charts, which suited a playstyle focused on treasure hunting. Although contemporary D&D often focuses on narrative and role-play, leading many DMs to feel they need exhaustive notes, this isn't always the required method.

Achieving the Healthy Equilibrium

It is perfectly no issue with thorough preparation. But, there is also no issue with stepping back and letting the whim of chance to guide minor details instead of you. Control is a big aspect of a DM's role. We need it to facilitate play, yet we often struggle to cede it, in situations where doing so might improve the game.

My final advice is this: Have no fear of letting go of your plan. Try a little improvisation for inconsequential details. It may create that the surprising result is infinitely more powerful than anything you might have planned in advance.
