It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Before it flies away, the duck reveals that there are two other entrances into the mountain. Meanwhile, Vex has slipped away to follow the footsteps around the mountain.
DM: All right. So you fly up. (flapping wings) 60 feet a round. It'll take you a good five minutes or so to make your way towards the top end of the spire. As you're going, make an investigation check.
Player: Can I stealth as cloud?
DM: Oh, you're going cloud! Sorry, I thought you were doing your wings. As a cloud, you get there really fast. So as you make it up there, you cannot-- I will say, for the purposes of this...
Player: I'm wind. I'm not going high, I'm going through the treetops.
DM: Yeah, so make a stealth check.
Player: All right, I will. That is very good. That is a 35.
DM: 35, okay. As far as you understand, no one seems to see you. Make an investigation check as you make your way up the mountainside to check for any sort of entrances.
