As a game master, I traditionally shied away from significant use of randomization during my tabletop roleplaying sessions. I preferred was for story direction and what happened in a game to be shaped by player choice instead of the roll of a die. However, I opted to try something different, and I'm truly happy with the result.

The Inspiration: Watching a Custom Mechanic

An influential actual-play show showcases a DM who often requests "luck rolls" from the participants. This involves choosing a specific dice and defining possible results tied to the result. It's essentially no different from rolling on a random table, these get invented in the moment when a course of events has no obvious outcome.

I chose to experiment with this technique at my own game, mainly because it appeared interesting and provided a change from my normal practice. The outcome were eye-opening, prompting me to reflect on the perennial tension between preparation and randomization in a tabletop session.

A Memorable Story Beat

At a session, my players had just emerged from a large-scale conflict. Later, a cleric character inquired after two key NPCs—a brother and sister—had survived. Rather than picking a fate, I handed it over to chance. I instructed the player to make a twenty-sided die roll. The stakes were: on a 1-4, both died; a middling roll, only one would die; on a 10+, they survived.

Fate decreed a 4. This resulted in a incredibly moving scene where the characters came upon the remains of their allies, still united in their final moments. The cleric held a ceremony, which was especially meaningful due to prior roleplaying. As a parting reward, I decided that the NPCs' bodies were miraculously transformed, revealing a spell-storing object. By chance, the item's contained spell was perfectly what the group lacked to address another pressing quest obstacle. You simply script such perfect story beats.

Honing Your Improvisation

This incident caused me to question if improvisation and thinking on your feet are truly the beating heart of this game. Although you are a meticulously planning DM, your ability to adapt may atrophy. Players often take delight in upending the most carefully laid plots. Therefore, a skilled DM needs to be able to think quickly and invent content on the fly.

Employing on-the-spot randomization is a excellent way to train these skills without venturing too far outside your usual style. The trick is to use them for small-scale circumstances that won't drastically alter the overarching story. As an example, I wouldn't use it to establish if the king's advisor is a traitor. Instead, I could use it to determine if the party reach a location just in time to see a key action occurs.

Enhancing Collaborative Storytelling

Spontaneous randomization also helps make players feel invested and cultivate the feeling that the adventure is dynamic, shaping in reaction to their choices as they play. It prevents the perception that they are merely pawns in a rigidly planned narrative, thereby enhancing the collaborative aspect of the game.

This philosophy has long been part of the original design. Original D&D were enamored with random tables, which suited a playstyle focused on treasure hunting. Even though modern D&D tends to emphasizes plot-driven play, leading many DMs to feel they require detailed plans, it's not necessarily the best approach.

Finding the Healthy Equilibrium

It is perfectly no problem with being prepared. However, there is also nothing wrong with letting go and letting the whim of chance to guide minor details rather than you. Control is a major aspect of a DM's responsibilities. We need it to manage the world, yet we can be reluctant to release it, even when doing so might improve the game.

The core advice is this: Have no fear of relinquishing a bit of control. Experiment with a little randomness for smaller details. It may find that the unexpected outcome is infinitely more powerful than anything you could have planned on your own.
