As a Dungeon Master, I traditionally steered clear of significant use of randomization during my tabletop roleplaying games. I preferred was for narrative flow and session development to be guided by deliberate decisions instead of the roll of a die. That said, I opted to change my approach, and I'm very happy with the result.

The Catalyst: Watching a Custom Mechanic

An influential actual-play show features a DM who regularly requests "fate rolls" from the participants. This involves choosing a specific dice and outlining possible results based on the result. This is essentially no distinct from consulting a pre-generated chart, these are devised on the spot when a course of events lacks a clear resolution.

I chose to experiment with this approach at my own game, primarily because it looked interesting and offered a change from my usual habits. The results were remarkable, prompting me to reflect on the perennial tension between planning and randomization in a D&D campaign.

A Memorable In-Game Example

At a session, my group had survived a massive conflict. Afterwards, a player asked about two key NPCs—a pair—had lived. Instead of deciding myself, I asked for a roll. I told the player to roll a d20. The possible results were: a low roll, both were killed; on a 5-9, a single one would die; on a 10+, they survived.

The player rolled a 4. This resulted in a profoundly moving scene where the characters discovered the remains of their companions, forever united in death. The group performed funeral rites, which was uniquely meaningful due to prior roleplaying. As a final touch, I decided that the NPCs' bodies were suddenly transformed, revealing a spell-storing object. I randomized, the bead's magical effect was precisely what the group needed to address another major quest obstacle. It's impossible to orchestrate this type of magical coincidences.

Sharpening On-the-Spot Skills

This incident caused me to question if chance and spontaneity are actually the essence of tabletop RPGs. Although you are a meticulously planning DM, your improvisation muscles can rust. Adventurers frequently find joy in upending the most carefully laid plans. Therefore, a effective DM needs to be able to adapt swiftly and fabricate details in real-time.

Utilizing similar mechanics is a excellent way to develop these skills without venturing too far outside your usual style. The trick is to use them for minor decisions that don't fundamentally change the session's primary direction. For instance, I would avoid using it to establish if the main villain is a secret enemy. Instead, I would consider using it to decide if the characters arrive just in time to see a major incident unfolds.

Empowering Shared Narrative

Luck rolls also works to make players feel invested and foster the feeling that the adventure is responsive, progressing according to their actions immediately. It reduces the perception that they are merely pawns in a pre-written script, thereby enhancing the cooperative aspect of the game.

Randomization has historically been embedded in the core of D&D. Original D&D were filled with random tables, which suited a game focused on exploration. Even though current D&D often prioritizes story and character, leading many DMs to feel they require detailed plans, it's not necessarily the best approach.

Finding the Right Balance

Absolutely nothing wrong with doing your prep. But, equally valid nothing wrong with relinquishing control and letting the whim of chance to decide some things rather than you. Control is a significant aspect of a DM's role. We use it to manage the world, yet we often struggle to give some up, even when doing so can lead to great moments.

A piece of recommendation is this: Do not fear of temporarily losing your plan. Embrace a little randomness for inconsequential story elements. The result could create that the organic story beat is infinitely more powerful than anything you could have scripted by yourself.
