In Tarant while on the second quest that Madam Lil gives you, when talking to 
Mr. Langley say that Madam Lil sent you. Then, choose either response (other 
than bye), then the one that begins with "[Menacing]", then say that you do 
not trust him, and finally choose "Okay [you take the coin] but I'll be back 
for the rest". After you are done, repeat this as many times as needed for 
free money.
Wait outside the wise woman's location in either Ashbury or Shrouded Hills 
until they have a large sum of money. Kill them and take the money. Make sure 
to leave one alive so you have someone that can identify your items.
Become a good pickpocket, then steal the key from Rizzette after dark. 
Note: Sneak into his room with him. Sell Rizzette either the camera or a 
clock part, then go into his room and steal the item back. Repeat this as 
many times as desired. Then, go to the Inn and ask the Innkeeper for a 
week's stay. Continue to sell Rizzette the item, steal it back, and sleep 
in the INN for the night. Rizzette will have a new supply of money every day.
