Prospecting
From Ancient Anguish Mud Wiki - AAwiki
Rhynst: Prospecting goes up incredibly slowly and is incredibly brain numbingly boring. You raise it by finding Dubo near the ranger camp, getting a prospecting pan and spending hours sitting around waiting for gold – rather like a real prospector, I’d imagine.
Tinuviel's comments: I enjoy raising mostly-useless abilities, but this one is truly the most painful. It's best done when you need to sit around healing hp/sp (perhaps before you go back to mining) and best done while you do something in another window or read a book, typing 'prospect' every couple of minutes. Definitely do not expect to get rich doing this. I'm at 34 for this ability after spending hours at it. I haven't had much luck with the rivers in Dubo's area, but rather in the northern rivers closer to Snowfolk guild. You can prospect on Infidian, too :)
