is there a way to get gold/money faster or you can only get it doing tasks? if so, i really think that enemies should always drop some money
if you have the mine unlocked (and a pickaxe) you can dig diabosite and sell it for some money, its faster than doing tasks or robbing the bandits
You also can get a decent amount of money from helping Bernard out all day. The 'all day' help is only available in the early morning, though, but it then doesn't really cut into your doing other moneymaking things.
