RE: Treasure Hunter in BH
Goto the old ghouls home, I think the room on the bottom left, there lives typho. He'll tell you about a treasure but won't tell you the location till you do a few quests for him... then do those quests (not much of quests really but anyway...), he'll tell you a vague description of the location and you'll gain 2000 exp. (stop reading here unless you want to be a cheater and not figure it out yorself)
Then you goto the town well, click on it, go through the train of thought, and then go talk to the treasure hunter and agree to split it 50 50. Have a good laugh on the consequences that follow and be sure to click on the well some more later for more amusement.
