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, The party, after essentially forcing this individual to reveal themself, the rakshasa fled through a tunnel underneath its room into a long subterranean tunnel fraught with traps that were set to protect it. The party managed to avoid these rather deftly until the steady decline of the hallway, combined with the increasing moisture and scent of refuse, caused a slick surface and our fantastic cleric, Brother Kash, Kashaw, slipped and fell down.
DM: Next to him? Okay, you will get free strikes from both the rat swarms, currently, because you'll be passing through there and out of their melee range. You cool with that?
Player: No, I'm not. Can I take a step back?
DM: You can. This guy will still get an attack of opportunity on you.
Player: Really? I thought I could move five feet.
DM: You can use an action to disengage.
Player: Okay. I won't do anything. Here's what I'm going to do instead. I'm sorry, I don't know what was wrong. I've been off, and I apologize for how I've been sounding. What I'm going to do is I'm going to lift my finger and I'm going to aim behind that three-headed bastard and I'm going to release a 4th-level Fireball.
DM: Over here?
Player: Yes.
DM: Show me with your laser pointer where you want the impact to be.
Player: Behind him where it won't hurt Keyleth and will just hurt him. Wherever that is.
DM: Okay. I'd say that'd probably be right around this area here.
Player: I'm going to immediately spend two sorcery points and quicken spell, and I'm going to turn around and do three Scorching Rays to follow up the Fireball right at that dude, each head.
DM: Okay.
Player: I'm going to, on that spell, spend another--
DM: Wait up, let's do the Fireball first.
Player: Okay.
DM: One thing at a time. So as you use your ring, you focus. The ray streaks past. Slams into the wall behind (explosion sound) with a deafening roar, and you guys definitely hear this. The hallway in the distance suddenly brightens up, and you can see a bit of flame roll up, and the scent of smoke comes wafting past you as a wave of heat blasts through the tunnel.
