Shhh! Silence! This requires total concentration. The study of levitation is that of an art, and even a small mistake will ruin everything. How about studying it with me? You do seem heavy for this... anyway, how can I help you? Do you have something to ... Hey! You! You must have eliminated 999 Green Mushrooms. I can see 999 Green Mushrooms hovering behind you. Incredible!

I can tell you're noble enough to do this without expecting anything return, but this is just my way of saying thank you for helping us out. Please take it.

You're not saying that you're going to end your journey here, right? Inside the Dungeon, you'll find nothing but really powerful, dangerous monsters. I've put up bulletin boards everywhere, so find those. I'll reward you well, if the job is done right. Watch out for those monsters!
