When I am a Dungeon Master, I usually shied away from extensive use of chance during my tabletop roleplaying games. I tended was for the plot and session development to be determined by character actions rather than random chance. Recently, I chose to try something different, and I'm incredibly glad I did.
An influential actual-play show showcases a DM who regularly asks for "luck rolls" from the adventurers. He does this by choosing a specific dice and outlining consequences contingent on the result. This is at its core no different from rolling on a pre-generated chart, these are created on the spot when a character's decision lacks a predetermined outcome.
I chose to experiment with this approach at my own game, mostly because it seemed novel and presented a break from my usual habits. The experience were remarkable, prompting me to reconsider the ongoing dynamic between preparation and spontaneity in a tabletop session.
At a session, my party had concluded a massive conflict. When the dust settled, a player asked about two friendly NPCs—a brother and sister—had lived. Instead of picking a fate, I asked for a roll. I asked the player to roll a d20. The stakes were: on a 1-4, both would perish; on a 5-9, a single one succumbed; a high roll, they survived.
The die came up a 4. This triggered a deeply moving scene where the party came upon the remains of their companions, forever united in their final moments. The cleric performed a ceremony, which was uniquely significant due to earlier story developments. As a parting gesture, I decided that the forms were strangely transformed, containing a enchanted item. By chance, the bead's magical effect was precisely what the group needed to solve another major story problem. One just orchestrate such magical coincidences.
This incident made me wonder if improvisation and spontaneity are truly the core of D&D. Although you are a meticulously planning DM, your skill to pivot can rust. Groups frequently excel at upending the best constructed plans. Therefore, a good DM has to be able to pivot effectively and fabricate details in the moment.
Employing similar mechanics is a great way to develop these abilities without straying too much outside your usual style. The key is to use them for small-scale situations that have a limited impact on the session's primary direction. To illustrate, I would not employ it to determine if the king's advisor is a secret enemy. But, I would consider using it to decide if the characters enter a room moments before a key action occurs.
Luck rolls also serves to make players feel invested and create the impression that the adventure is responsive, progressing based on their decisions as they play. It prevents the feeling that they are merely actors in a rigidly planned story, thereby enhancing the shared aspect of the game.
Randomization has historically been embedded in the game's DNA. Early editions were reliant on encounter generators, which made sense for a game focused on exploration. Even though current D&D tends to emphasizes plot-driven play, leading many DMs to feel they require detailed plans, this isn't always the required method.
It is perfectly nothing wrong with being prepared. However, equally valid nothing wrong with stepping back and letting the rolls to decide some things instead of you. Direction is a big part of a DM's role. We need it to run the game, yet we frequently find it hard to cede it, in situations where doing so can lead to great moments.
My final advice is this: Do not fear of temporarily losing the reins. Try a little improvisation for inconsequential story elements. It may discover that the surprising result is infinitely more memorable than anything you might have pre-written on your own.
