Kash:
Ha! You get points for courage, if nothing else! But I wouldn't advise that you hunt there all by yourself. Courage alone won't get you very far against a centuries-old Medusa, youngster! That thing must have learned a few tricks over the years, eh? I think you'd best round up a group of your friends before trying your luck against the stone-looker.
Here, take this Dimension Diamond and hold on to it. You can trade it to the village gatekeeper for something special that may help you on your journey.
