As a game master, I usually avoided heavy use of randomization during my tabletop roleplaying games. I preferred was for narrative flow and what happened in a game to be guided by player choice as opposed to the roll of a die. Recently, I decided to try something different, and I'm truly happy with the result.

The Inspiration: Watching a Custom Mechanic

An influential actual-play show features a DM who frequently asks for "luck rolls" from the adventurers. This involves selecting a type of die and assigning potential outcomes contingent on the number. It's essentially no unlike using a random table, these are created in the moment when a player's action lacks a predetermined resolution.

I decided to try this method at my own game, mainly because it seemed interesting and provided a break from my usual habits. The outcome were fantastic, prompting me to reconsider the often-debated tension between pre-determination and randomization in a roleplaying game.

A Powerful In-Game Example

In a recent session, my group had just emerged from a city-wide conflict. When the dust settled, a player asked about two friendly NPCs—a sibling duo—had survived. In place of deciding myself, I handed it over to chance. I asked the player to roll a d20. The stakes were: on a 1-4, both died; on a 5-9, a single one succumbed; on a 10+, they made it.

Fate decreed a 4. This led to a profoundly moving sequence where the party found the remains of their allies, still clasped together in their final moments. The group held last rites, which was especially powerful due to prior roleplaying. In a concluding touch, I improvised that the remains were suddenly restored, containing a enchanted item. By chance, the item's contained spell was precisely what the group lacked to resolve another critical quest obstacle. One just script this type of serendipitous story beats.

Sharpening DM Agility

This event made me wonder if improvisation and spontaneity are in fact the beating heart of tabletop RPGs. While you are a detail-oriented DM, your improvisation muscles can rust. Adventurers frequently find joy in upending the best constructed plans. Therefore, a skilled DM must be able to pivot effectively and invent content in real-time.

Employing similar mechanics is a excellent way to develop these abilities without straying too much outside your usual style. The trick is to apply them for minor circumstances that have a limited impact on the campaign's main plot. As an example, I would not employ it to decide if the central plot figure is a secret enemy. But, I could use it to determine whether the party reach a location moments before a major incident occurs.

Enhancing Collaborative Storytelling

Luck rolls also serves to maintain tension and create the feeling that the story is dynamic, progressing according to their choices in real-time. It prevents the perception that they are merely pawns in a rigidly planned story, thereby enhancing the collaborative nature of storytelling.

This philosophy has long been integral to the original design. Early editions were enamored with charts, which made sense for a playstyle focused on dungeon crawling. While modern D&D frequently prioritizes plot-driven play, leading many DMs to feel they require detailed plans, that may not be the only path.

Finding the Right Balance

There is absolutely no problem with thorough preparation. Yet, equally valid no problem with letting go and allowing the dice to determine certain outcomes in place of you. Control is a major part of a DM's responsibilities. We require it to facilitate play, yet we frequently find it hard to give some up, at times when doing so might improve the game.

A piece of advice is this: Do not fear of relinquishing a bit of the reins. Embrace a little chance for smaller outcomes. You might just discover that the organic story beat is infinitely more memorable than anything you would have pre-written by yourself.
