Tips to Farm Gold and Building Faction
Build a Faction
One way to build a faction is to wait for a hero to rebel and start their own faction. Then join them and then take a minor settlement. Then he’ll likely give it to you do to few other options. Then you rebel. You’ll be at war with that hero but everyone else shouldn’t hate you.
To farm gold one way is to buy gold and silver from Golden Bazaar and sell them in Umbra Cliffs down south, or the swamp map.
