As a DM, I usually shied away from significant use of randomization during my D&D adventures. I preferred was for story direction and session development to be guided by character actions as opposed to the roll of a die. That said, I decided to change my approach, and I'm very glad I did.

The Spark: Watching a Custom Mechanic

A well-known actual-play show features a DM who regularly asks for "luck rolls" from the participants. This involves choosing a specific dice and defining potential outcomes based on the number. It's at its core no different from rolling on a random table, these are devised spontaneously when a character's decision lacks a clear conclusion.

I decided to try this technique at my own table, mainly because it looked interesting and offered a departure from my normal practice. The outcome were fantastic, prompting me to reconsider the ongoing balance between pre-determination and improvisation in a tabletop session.

A Memorable In-Game Example

During one session, my party had concluded a massive conflict. Afterwards, a cleric character wondered if two beloved NPCs—a brother and sister—had survived. Instead of deciding myself, I asked for a roll. I asked the player to roll a d20. The possible results were: on a 1-4, both were killed; on a 5-9, a single one succumbed; a high roll, they made it.

The die came up a 4. This resulted in a deeply poignant sequence where the adventurers came upon the corpses of their friends, still clasped together in their final moments. The party held last rites, which was particularly significant due to prior story developments. As a parting touch, I improvised that the forms were strangely transformed, containing a magical Prayer Bead. I rolled for, the bead's magical effect was exactly what the group lacked to resolve another critical quest obstacle. It's impossible to plan such serendipitous coincidences.

Honing Your Improvisation

This event made me wonder if chance and spontaneity are actually the essence of tabletop RPGs. Although you are a detail-oriented DM, your skill to pivot may atrophy. Players often find joy in upending the best constructed plans. Therefore, a good DM needs to be able to think quickly and invent details in the moment.

Utilizing luck rolls is a fantastic way to practice these skills without venturing too far outside your comfort zone. The trick is to deploy them for low-stakes situations that have a limited impact on the session's primary direction. As an example, I would not employ it to decide if the king's advisor is a secret enemy. However, I might use it to decide if the PCs enter a room right after a critical event occurs.

Empowering Collaborative Storytelling

This technique also serves to make players feel invested and create the impression that the game world is alive, progressing based on their actions in real-time. It combats the perception that they are merely characters in a rigidly planned script, thereby bolstering the collaborative foundation of the game.

This approach has long been embedded in the core of D&D. The game's roots were reliant on charts, which fit a game focused on treasure hunting. Even though current D&D frequently prioritizes story and character, leading many DMs to feel they must prep extensively, that may not be the required method.

Finding the Right Balance

There is absolutely no problem with doing your prep. However, it's also fine nothing wrong with stepping back and allowing the rolls to guide minor details in place of you. Direction is a major factor in a DM's job. We need it to manage the world, yet we can be reluctant to release it, even when doing so could be beneficial.

My final suggestion is this: Do not fear of relinquishing a bit of the reins. Try a little improvisation for smaller details. You might just find that the unexpected outcome is significantly more powerful than anything you might have planned on your own.
