It's a fantasy role-playing game.

DM: You are Grog Strongjaw, a goliath barbarian . 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: All right, so they're all going to take javelin shots at-- miss. Miss. Two-- miss. Hit. Hit. Three hits. And so they're all just (effort sounds) chucking these javelins upward. Four, eight, that's 12, plus seven-- 19 points of damage from the javelins as some stick in then fall out, the wounds are now becoming visible. Umbrasyl's-- there's visible wounding but doesn't appear to be in dire straits or anything. Grog, you're up.
Player: Yes, I have two questions. One of the things I picked up from Kevdak were four enchanted javelins. What do those do?
DM: They're thrown, ranged attacks.
Player: And they're just enchanted?
DM: They're plus one to hit and damage.
Player: Just that.
DM: That's it, yeah. It's a relatively simple enchantment.
Player: What is my climbing speed? If my natural speed is 50 and I wanted to climb that column, what's the climbing speed?
DM: Climbing speed? I mean, if you roll a decent climb check-- here. That would be-- I'd say that would be an athletics check to see if you can climb it, and I'd put it at about half speed. But you're also prone, so getting up from that's half your speed.
Player: On my back, can I use my bonus action to drink the potion of speed, which makes me hasted?
DM: Yes you can. You now have technically four attacks per round.
Player: I do. And it doubles my speed, right?
DM: Yes.
Player: Okay, so I have 100 feet, so can I stand up?
DM: Yep. 50 feet.
Player: Can I try and climb that column towards Umbrasyl's feet?
DM: Athletics check.
Player: That's not awesome. 18.
DM: 18. You just manage to get to the top with the last bit of your movement. So you are up about ten feet from Umbrasyl right now, pushing on 15 at an angle.
Player: So I have four attacks?
DM: Yes. You're not in melee, though.
Player: Yeah, so I'll use three of the enchanted javelins and the javelin of lightning.
DM: Okay. All right, so you (effort sounds) finally with the javelin of lightning. So go ahead and make the first three strikes.
Player: Reckless, all of them.
DM: Okay, so with advantage on each of these. The range on the javelin strikes, I'm just going to pull it up real fast, since this is the first time you've used this.
Player: Yeah, it's 120 feet for the javelin of lightning.
DM: Yeah, within 30-foot range, so it's fine. Go ahead and roll. First one is?
Player: It's an 11 plus-- just my natural like--
DM: It's 11 plus one for being enchanted.
