It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, The bear clamps his jaws over the vampire's head and tears it off, the body turning to mist as he screams in pain. The mist hovers in place.
DM: There's still some thick, purplish, congealed blood in his mouth, but the vampire's form has been forced to mist at zero hit points. All right, that brings us to Keyleth.
Player: Okay! So seeing Vax go over the table and being like, "That was cool," I'm also going to be like (grunts) over the table. I'm going to join the Dukes of Hazzard train.
DM: Acrobatics check.
Player: Damn it. That's not bad!
DM: It's not a huge difficulty.
Player: Acrobatics? 17?
DM: 17, yeah. You jump up (shh) slide across, land across. The bonus there is that it takes only one block of movement to get across. That's five foot there.
Player: So I'm going to come in and I see a headless dude with mist swirling around him?
DM: No, you just see Grog, Vax, and Trinket in the center of this foyer, with a big cloud of mist near Trinket and Grog, and an entire array of guards with heavy crossbows trained down on the three of them in this ambush pit.
