Chance Rolls in D&D Can Help You Become a More Effective Dungeon Master

As a Dungeon Master, I historically shied away from heavy use of randomization during my tabletop roleplaying sessions. My preference was for story direction and what happened in a game to be guided by player choice as opposed to pure luck. Recently, I chose to change my approach, and I'm truly glad I did.

The Catalyst: Watching a Custom Mechanic

An influential actual-play show utilizes a DM who frequently requests "chance rolls" from the players. He does this by picking a type of die and outlining consequences based on the roll. This is fundamentally no unlike consulting a random table, these are created spontaneously when a player's action lacks a predetermined outcome.

I opted to test this technique at my own game, mostly because it looked engaging and provided a departure from my normal practice. The results were remarkable, prompting me to reflect on the perennial balance between preparation and randomization in a D&D campaign.

A Memorable Session Moment

At a session, my players had just emerged from a large-scale fight. Later, a player inquired after two friendly NPCs—a sibling duo—had survived. In place of choosing an outcome, I let the dice decide. I told the player to make a twenty-sided die roll. The stakes were: a low roll, both were killed; a middling roll, only one would die; on a 10+, they made it.

The die came up a 4. This resulted in a incredibly emotional scene where the characters discovered the bodies of their allies, forever united in death. The group performed a ceremony, which was uniquely significant due to prior character interactions. In a concluding gesture, I decided that the remains were suddenly restored, containing a magical Prayer Bead. I randomized, the item's contained spell was exactly what the party lacked to resolve another major story problem. It's impossible to orchestrate such perfect moments.

Honing Your Improvisation

This experience led me to ponder if improvisation and spontaneity are in fact the core of D&D. Although you are a meticulously planning DM, your skill to pivot can rust. Players reliably take delight in upending the most detailed narratives. Therefore, a skilled DM must be able to think quickly and fabricate scenarios on the fly.

Using luck rolls is a excellent way to train these skills without going completely outside your usual style. The strategy is to apply them for minor circumstances that have a limited impact on the session's primary direction. For instance, I wouldn't use it to decide if the king's advisor is a secret enemy. However, I could use it to decide if the PCs reach a location moments before a major incident unfolds.

Empowering Shared Narrative

Spontaneous randomization also serves to make players feel invested and create the sensation that the adventure is responsive, shaping based on their choices immediately. It combats the feeling that they are merely actors in a DM's sole story, thereby bolstering the shared foundation of roleplaying.

This philosophy has long been integral to the core of D&D. Early editions were reliant on encounter generators, which fit a game focused on exploration. Even though modern D&D tends to emphasizes story and character, leading many DMs to feel they require detailed plans, that may not be the only path.

Striking the Healthy Equilibrium

There is absolutely no problem with being prepared. Yet, it's also fine no issue with stepping back and letting the whim of chance to determine certain outcomes rather than you. Authority is a major factor in a DM's role. We require it to run the game, yet we can be reluctant to release it, even when doing so can lead to great moments.

My final recommendation is this: Don't be afraid of temporarily losing the reins. Embrace a little improvisation for smaller details. The result could create that the unexpected outcome is infinitely more rewarding than anything you might have pre-written on your own.
