It's a fantasy role-playing game.

DM: You are Tiberius Stormwind, a dragonborn sorcerer . You are the member of the famous group of adventurers. Previously, Across from the entrance is a set of wooden doors which he listens at. He hears nothing, but notices that the door is unlocked.
DM: Okay, so. Tiberius, as you're backing up, both the duergar turn around immediately, seeing you, and rear back with javelins, throwing them directly at you.
Player: Oh! I'll cast Blur instead.
DM: Okay. Go ahead and roll initiative real fast to see who gets off first what.
Player: I'm not going to count that. Oh, I'll count that. 19.
DM: What, why didn't you count it?
Player: Because it flew out of my hand, I didn't roll it.
DM: Okay. All right.
Player: Yeah. It's on camera, tell them to play back.
DM: So you go ahead and cast Blur. You guys see as Tiberius comes running back, (startled sounds). He manages to cast a spell really fast as two javelins come flying towards him. His visible image begins to actually blur; the outline looks almost like there's two mirror images of Tiberius in the same place that are both shimmering and preventing them from actually telling where he's actually standing. The first javelin comes in at a 14.
Player: Nope.
DM: Second one comes in at a 17.
Player: 17. Yes.
DM: Oh sorry, no, it's a four, 'cause it has disadvantage. So both javelins just whish past. Looks like they pierced part of that kinda shimmering blurring form, but both just ricochet off the walls of stone and come clattering to the ground. Kinda near back where Kima and Grog are. They both step out of the way as they land.
