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, Vax pulls Scanlan aside and pitches him a backup plan. He wants to have Scanlan Dimension Door into Umbrasyl's stomach and use the unmovable rod to hurt him from inside.
DM: Four. Fassbender's still standing there. On a five or six, it recharges. That ends Vax's turn. Keyleth, you're up.
Player: Okay. As an earth elemental I want to drop into the earth and Earthglide.
DM: All right. How many feet are you going?
Player: With my 60 feet-- question, can I get across and to the top of this pillar here? Maybe?
DM: Oh, right there?
Player: That one.
DM: You can get up to there. You're wider than the pillar, though. You like--
Player: Earthglide to the top, so it's 30 feet tall. (nervous laughter) And I'm going to use my momentum to see if I can rocket myself out and see if I can jump and grab onto his leg.
DM: Okay, so you're making this a jump action, then?
Player: Yeah, I want to shoot out of the pillar.
DM: Using the momentum of the Earthglide?
Player: And shoot out with a waterslide trajectory, woo! Yeah? Maybe?
DM: Okay. I'll say that-- It's pretty fast-- Also pretty heavy as an earth elemental.
Player: I'm thinking about it real hard.
DM: Go ahead and make an athletics check.
Player: So is that strength as a--
DM: That would be strength as an earth elemental if you do not have a specific skill for it.
Player: I'm going to use Scanlan's inspiration. Ooh, that's good. 18 plus five, so, 23.
DM: 23. You manage to leap and catch the bottom of its foot. (cheering) You're not halting or doing anything to Umbrasyl other than the fact that you're holding on to--
Player: But I've got his foot. And I'm heavy as fuck. Well, if Fassbender weighs, what was it, like 1,200 pounds? 2,800 pounds?
DM: Yeah.
Player: So I'm at least as heavy if not heavier than Fassbender. A ton is 1,000 pounds. Right?
DM: 2,000.
