The other day, I read a playtest version of a Dungeons & Dragons Adventurers League Excursion. Instead of the usual linear series of encounters, this adventure introduced an unprecedented element of chance. From the start, random encounters lead players onto different courses. The final showdown can occur in a randomly-determined location. Much of the combat comes from random confrontations with 1d4 of this or 1d6+1 of that.

This unusual element of chance led me to consider the benefits of giving the dice control over much of a role-playing game characters’ fate.

Random chance increases replay value. From the seeded worlds in Minecraft to the random dungeons in Diablo, replay value concerns video games more than tabletop games. In D&D, only the most devoted organized-play participants replay adventures. For those folks, letting the dice shape the game yields variety from a single adventure.

Random chance creates surprises for the game master. The dice can add unexpected ingredients to the game master’s plan for a session. This can add to the fun. Plus, adding the unexpected—or just working to make sense of it—leads GMs to inspiration. For example, during a session where my players traveled by boat, the random combination of a waterfall and drowned ghouls forged a memorable encounter.

Nonetheless, when I serve as game master, my players’ choices create enough surprises for me. If your players never surprise you, then you probably haven’t given them enough freedom.

In role-playing games, much of the players’ fun comes from weighing choices. Before you let a die roll plot an adventure, ask whether the players’ decisions could provide the same spin. For example, rather than having the players randomly meet a faction in the dungeon, let them uncover enough clues to choose which faction to pursue. Or on a small scale, if a charging demon faces many ripe targets, ask if anyone wants to taunt the creature. Arrange choices so that even you cannot imagine which the players will select. Practice by splitting slices of cake to share, and then giving your kid brother first pick.

Random chance separates the players’ success or failure from the game master’s fiat. In a role-playing game, no one wants the GM to control the characters’ fate. When player characters succeed, the players want credit for the victory; when PCs fail, the game master wants the dice to take the blame. To assure my players that I don’t meddle with their characters’ fortunes, I roll dice in plain sight. A good GM acts as a facilitator and impartial referee, not as a Fate who controls destiny.

As a game master, do you ever roll a die to check which player character a monster will target? Years ago, as I plotted my monster’s tactics, I left the players to figure out the creatures’ motivations. If I rolled a die to choose a target, I did it secretly.

My secret approach led players to complain that I singled out their characters for attack. Apparently, all the players felt singled out, and they were especially singled out when they rushed into a crowd of monsters. (I never single out players. Unless they boast that they never take damage. Then maybe a little.) So I switched my approach. Now I help players understand why they get targeted. Sometimes the clues come in character. The monsters say, “You hurt Grog, so now you die,” or “Slay that accursed priest first, so he cannot heal the others.” This peek into the monsters’ choices gradually improved the players’ tactics.

When monsters lacked an obvious target, I started rolling in plain sight to decide. The die roll may cost a bit of immersion, but players cannot accuse the die of playing favorites.

To impartially settle questions about the game world, many GMs use die rolls. For instance, when the player of a drow asked whether burning wreckage on the battlefield made enough smoke to shroud his PC from the sun. I rolled. “On a 1 to 3, then yes.”

Random rolls reduce the GM’s power to control the game. In a sense, these rolls unite game master and players in a shared enterprise. Everyone watches the roll of the dice together and shares the surprise when the result shows where fate will take them.
