Requirements

Offer: Wouldn't it be incredible to swim in those clouds and fly your way through freedom? I wonder what it's like to fly, free as a bird. Even if it's only for a few minutes, I'd be more than happy to just be up there!
Oh yeah, I truly believe we're meant to fly, and I will try my hardest to make that wish come true! That got me thinking, in order to fulfill my dream, I should make a huge hang glider! I read it in a book, and it says we can fly like a bird with the hang glider in place. All I need now is a set of materials needed to build it, and... do you want to help me out here? If you get me the materials, I'll definitely let you ride on it. What do you think?
In progress: Did you get all the materials I asked? I don't think you have all of them! Please gather up 50 Stirge Wings, 10 Processed Woods, and 50 Stiff Feathers! The faster you get them for me, the earlier we'll be floating up in the air!
Completion: I've been waiting for a loooong time! While you were out gathering up the materials, I have drawn up the perfect blueprint for it! All we need now is to follow through with the plan, and we'll be up in the skies in no time! Did you gather up all the materials?
