When I am a DM, I usually shied away from heavy use of randomization during my tabletop roleplaying adventures. I tended was for story direction and session development to be determined by deliberate decisions instead of random chance. That said, I chose to change my approach, and I'm truly glad I did.

The Inspiration: Observing an Improvised Tool

A popular podcast features a DM who often asks for "luck rolls" from the players. This involves choosing a polyhedral and defining potential outcomes contingent on the result. This is essentially no distinct from consulting a pre-generated chart, these get invented spontaneously when a course of events has no obvious outcome.

I chose to experiment with this method at my own session, primarily because it appeared interesting and provided a change from my standard routine. The outcome were eye-opening, prompting me to reconsider the often-debated balance between preparation and improvisation in a tabletop session.

A Powerful Story Beat

In a recent session, my group had just emerged from a massive fight. Later, a player asked about two key NPCs—a sibling duo—had made it. Instead of choosing an outcome, I asked for a roll. I asked the player to roll a d20. I defined the outcomes as: a low roll, both died; a middling roll, only one succumbed; on a 10+, they both lived.

The player rolled a 4. This triggered a deeply emotional scene where the party came upon the corpses of their allies, forever holding hands in death. The cleric held funeral rites, which was especially powerful due to earlier story developments. As a parting gesture, I decided that the forms were strangely transformed, containing a spell-storing object. By chance, the item's magical effect was precisely what the party lacked to resolve another pressing situation. You simply plan this type of serendipitous coincidences.

Sharpening DM Agility

This experience caused me to question if improvisation and spontaneity are truly the essence of tabletop RPGs. While you are a meticulously planning DM, your skill to pivot need exercise. Players reliably take delight in ignoring the best constructed narratives. Therefore, a skilled DM must be able to think quickly and invent content in the moment.

Employing on-the-spot randomization is a fantastic way to develop these abilities without going completely outside your usual style. The strategy is to use them for minor circumstances that have a limited impact on the campaign's main plot. To illustrate, I wouldn't use it to decide if the main villain is a traitor. But, I could use it to decide whether the party enter a room just in time to see a key action unfolds.

Strengthening Shared Narrative

Luck rolls also helps make players feel invested and create the impression that the adventure is alive, progressing based on their actions as they play. It prevents the sense that they are merely characters in a pre-written story, thereby bolstering the cooperative foundation of storytelling.

This approach has historically been integral to the original design. Original D&D were filled with charts, which suited a playstyle focused on treasure hunting. While contemporary D&D tends to emphasizes plot-driven play, leading many DMs to feel they require detailed plans, that may not be the only path.

Finding the Healthy Equilibrium

Absolutely nothing wrong with thorough preparation. However, equally valid no problem with stepping back and permitting the dice to decide some things rather than you. Control is a significant part of a DM's responsibilities. We require it to run the game, yet we frequently find it hard to cede it, in situations where doing so can lead to great moments.

The core advice is this: Do not fear of letting go of your plan. Embrace a little randomness for smaller outcomes. The result could create that the surprising result is infinitely more rewarding than anything you could have scripted in advance.
