In my role as a DM, I usually shied away from heavy use of randomization during my Dungeons & Dragons sessions. My preference was for story direction and session development to be shaped by player choice as opposed to the roll of a die. Recently, I chose to try something different, and I'm incredibly glad I did.

The Catalyst: Watching 'Luck Rolls'

An influential streamed game showcases a DM who frequently requests "chance rolls" from the participants. The process entails picking a type of die and defining potential outcomes based on the number. This is fundamentally no different from consulting a pre-generated chart, these are devised on the spot when a course of events doesn't have a clear outcome.

I chose to experiment with this approach at my own game, primarily because it looked novel and presented a departure from my normal practice. The experience were remarkable, prompting me to reconsider the perennial dynamic between preparation and improvisation in a tabletop session.

A Memorable Story Beat

In a recent session, my party had concluded a massive fight. Afterwards, a cleric character inquired after two key NPCs—a brother and sister—had survived. Rather than picking a fate, I let the dice decide. I asked the player to make a twenty-sided die roll. I defined the outcomes as: on a 1-4, both were killed; on a 5-9, a single one would die; a high roll, they both lived.

The player rolled a 4. This led to a deeply emotional moment where the characters discovered the remains of their companions, still united in death. The group held last rites, which was especially meaningful due to prior roleplaying. As a final reward, I chose that the NPCs' bodies were strangely restored, revealing a magical Prayer Bead. By chance, the bead's magical effect was exactly what the group lacked to solve another major situation. One just plan this type of perfect coincidences.

Sharpening DM Agility

This event made me wonder if chance and thinking on your feet are truly the core of tabletop RPGs. Even if you are a meticulously planning DM, your improvisation muscles can rust. Groups reliably take delight in ignoring the best constructed plots. Therefore, a effective DM has to be able to adapt swiftly and invent content in real-time.

Employing luck rolls is a great way to develop these abilities without venturing too far outside your comfort zone. The key is to deploy them for minor decisions that won't drastically alter the campaign's main plot. For instance, I wouldn't use it to establish if the king's advisor is a traitor. Instead, I would consider using it to determine if the PCs enter a room right after a key action takes place.

Enhancing Player Agency

This technique also works to keep players engaged and create the sensation that the story is responsive, shaping according to their decisions immediately. It prevents the sense that they are merely pawns in a rigidly planned story, thereby strengthening the cooperative nature of roleplaying.

This approach has historically been embedded in the core of D&D. Early editions were filled with encounter generators, which suited a playstyle focused on dungeon crawling. Although contemporary D&D frequently focuses on narrative and role-play, leading many DMs to feel they need exhaustive notes, it's not necessarily the required method.

Finding the Right Balance

It is perfectly no problem with thorough preparation. However, equally valid no issue with relinquishing control and allowing the rolls to decide some things in place of you. Control is a major factor in a DM's role. We require it to manage the world, yet we can be reluctant to release it, at times when doing so could be beneficial.

My final advice is this: Don't be afraid of temporarily losing the reins. Experiment with a little improvisation for inconsequential outcomes. You might just create that the unexpected outcome is infinitely more rewarding than anything you could have pre-written in advance.
