Here are a cupple of ways 2 earn money.1) Quests I usely do easy-difficult ones.2) attack I usely use the red potion from store that's 5k and go for the ones with good loot.3) buy cheep allies and alot then when some bought do it over and over again.4) get a group of people and keep buying one guy at the end everyone gets money but one
A few things: red potions are terrible. If u are gonna attack ppl, get allies. The more expensive the better and don't worry about the stats. I they cost more, they get u more plunder bonus which will raise the amount u earn from winning a battle.
