It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, Keyleth, maintaining concentration on Grasping Vine, grabs the helmed horror next to Scanlan and drags it towards her. She then attempts to hit it with her staff but the attack is deflected easily due to how thick the armor is.
DM: Okay. He is technically in melee with you, so you get disadvantage on these strikes unless you want to move away.
Player: Does he get an attack of opportunity, though, if I scooch back?
DM: He would, unless-- he didn't take one against you when you ran back because you disengaged, so yes, he would.
Player: Okay, yeah.
DM: Okay, so you move back a step. That is a 21.
Player: Hits.
DM: Okay, you take nine points of slashing damage as you reach back. The creature (whoosh) arcs with its sword and manages to strike you.
Player: Bastard!
DM: Roll for your attacks.
Player: Okay, that is a 26 and a 23.
DM: Both hit.
Player: I didn't Hunter's Mark him, because I'm brilliant. Yes! 15, 30, 34 points.
DM: 34 points of damage for both?
Player: Yeah, two eights. Plus 14. Plus my bracers.
DM: Right. You pull the arrows out and launch them both simultaneously, two arrows in one notch; release them both. One slams into the armor. That one goes underneath the helmet, and as it strikes you hear this horrible echoing (screeching) screech that echoes as the armor (thud) falls to the ground.
