Often the most exciting moments in Dungeons & Dragons come from die rolls. When we throw the dice, dungeon masters and players alike surrender control to chance. Dice add surprise and risk to the game. See D&D and the Role of the Die Roll, a Love Letter.
Every D&D game has rolls important enough to grab everyone’s attention. Does the dragon’s breath weapon recharge? Did the inspirational speech win an ally? A die roll can spell the difference between victory or defeat, and sometimes between life and death. As a DM, you can spotlight these moments to heighten the drama and excitement.
Even DMs who typically roll in secret can benefit from making some rolls in the open.
Choose rolls that bring high enough stakes to grab attention.
Make sure you feel comfortable honoring the outcome of the roll, whatever it brings.
Announce what the roll means. “If the lich fails this save, it dies. Otherwise, it’s turn comes next and it has an 8th-level spell ready to cast.”
Announce the target number. For maximum drama, don’t make players wait for you to interpret the results. Tell everyone the number to look for on the die. “The lich needs a 13 or better to save.”
Then throw the die into the middle of the table. Let everyone watch the roll together and share the surprise when the result shows where fate will take them.
For some rolls a DM would usually make, I sometimes ask a player to make the roll. For example, I almost always ask a player to roll to see if a monster’s big attack recharges.
D&D’s lead rule designer Jeremy Crawford favors this trick too. “Sometimes I love making it impossible for myself to fudge rolls and will have players roll for me. Partly because as any DM will be able to attest, it’s too tempting when you tell yourself I’ll just roll to see what’s going to happen, but then you look at the die and think ‘eh, I don’t really like that result.’
“There’s something powerful about giving it to the players, and then we’re all agreeing we’re handing over the decision to fate. When I’m feeling particularly impish as a DM, I like having the players do it especially when it’s something bad because then they don’t feel like the DM did that to me. You rolled the die.”
We don’t use this stunt because we worry that players think we can’t be trusted with the roll. Instead the trick works because we all can feel like if we want a certain roll strongly enough, we might sway the outcome. Sure, those of us who play D&D rather than Las Vegas recognize that sense of control for a lie, but we feel it all the same. That feeling heightens the drama of the roll. The DM didn’t make things go wrong. I rolled the die.
The trick of explaining a roll, naming the target number, and then having a player cast the die works especially well for random encounters.
In a dungeon, the threat of random encounters forces urgency on players. Instead of slowing down for painstaking caution, and instead of stopping to chop down a locked door, characters have to keep moving. In the wilderness, random encounters give a journey more weight than “You spend three weeks travelling from Waterdeep to Neverwinter without incident.” (Sometimes you may want to fast-forward through a trip; other times distance should matter.)
For random encounters to benefit your game, players need a sense of the threat of wandering monsters. Nothing makes the threat more obvious than saying, “You’ve spent an hour in the tomb. Someone roll a d20 for me. On a 17 or higher, something bad happens.” See You Roll for Random Encounters Wrong (and so Do I).
