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, A scuffle ensues as they chase down a necromancer, a number of cultists, and some creatures from the Shadowfell. During the fray, Scanlan gets Sprigg back on his feet, and Keyleth kill a couple of the cultists with a Firestorm.
DM: You know what? Yes, because he was not stealthing. You watch as he darts by, and you would have a shot, yeah.
Player: All right, then I'm going to shoot at him. I'm going to Hunter's Mark him!
DM: All righty, look at that!
Player: Trinket doesn't have enough movement to get over by him, does he?
DM: No, but Trinket can attack whatever's in your area, too.
Player: I'm going to attack him with my Bramble Shot. With the Blazing Bowstring. Ooh, yeah. That's a 31.
DM: 31? That hits!
Player: Yes! Okay! Do I get sneak attack on him? I don't, do I?
DM: No.
