read the skill list page. One thing that needs to be corrected (assuming this is author's error) the money drops he picks up "could undermine the economy of a nation", is false. It could hurt a more modern civilization that uses notes as currency as those (in practice) are backed by the country and the value can be traded to that country for whatever goods are used to back it (typically gold). His drops however are coins, and coins are not backed by a nation, rather the value lies in the metal the coin itself is made of. plus, were talking about a primitive society, you could probably double the amount of coins the collective country has and it wouldnt be noticed.
