To get more gold here is a old trick the Flag ship named "The Colossus" is near Tormenta and when you sink it you'll get a decent amount of loot and treasure.
Well, you could go to General Darkhart. He gives VERY good gold. You could even get 1000+ gold in a skull chest from him!
Or if you're kind of weak such as levels 1-15 you can just redeem codes LOOT and BOUNTY.
