Dungeons & Dragons games live in our imagination, so we can only share the action through our description. Critical hits, high-stakes saves, and successful checks against long odds all encourage dungeon masters and players to describe the game’s action in ways that flaunt the characters’ power and talent. Everyone loves a crit; even narrating one is fun.
As a DM, I look for characters’ heroic moments. In a movie, a heroic moment might come when Wonder Woman rushes a foe through a window, crashing out in a shower of glass and debris. In a game, heroic moments come when a hero grapples Acererak and heaves him into a pool of lava, or when a hero stops fleeing an onrushing boulder and turns to drive the sword Shatterspike into it. Whenever you spot a heroic moment, put game time into slow motion and lavish description on the heroics. Make it awesome. Many players enjoy describing their characters’ heroic moments. Invite them to.
In D&D and in fiction, a heroes prove their mettle by facing villains who seem at least as capable of winning the day. So look for villainous moments—baddass occasions when your monsters get to flaunt their menace. Think of the Darth Vader demolishing rebels in pursuit of the stolen Death Star plans. D&D monsters typically arrive outmatched by heroes, so make the most of every badass turn. Legendary resistances invite badass moments by letting villains shrug off a hero’s best shot and laugh at the character’s weakness.
Surely none of this advice surprises you. Here’s the unexpected tip: When someone fumbles, instead of describing the failure in a way the makes the hero or monster seem inept or comical, describe the stumble so the fault comes from tough opposition or an imposible situation. DMs feel tempted to narrate bad rolls for laughs. We can narrate a 1 with a description of how someone’s hat tilted to cover their eyes and gain an easy laugh that feels fun in the moment. But too many descriptions like that turn characters into clowns and their opponents into jokes. Instead, use a 1 to describe a foe’s superhuman speed or the swirling hot ash clogging the air and stinging the heroes’ eyes. When you describe outcomes, even the fumbles, flatter your heroes and monsters.
Postscript: Before anyone runs to the comment section, I know that D&D lacks fumbles, but you know what I mean. Don’t be pedantic.
