Its very hard to get millions of gold to pay for big upgrades right? Not with this method! Choose what ever hero you please. (Top three most mana is best) Play through the game (multiple times may be necessary), get a team of archers (witch, cannon, mermaid, centaur, that sort of thing) beat every town except the last map. Then when you go into battle, just let your troops idle. If they are at least lvl 4 all, they will hold off the enemy troops. Check occasionally and have them keep retreating to the castle. This can rack up kills and coins. Once you thing you have enough, surrender and spend as you please. + to keep alive!
To point out a possible reference. The bracer scroll slightly relates to the scroll that can be worn on the head in Diablo 1 to give huge attack rating bonus. I'm not entirely sure if it is, but for you Blizzard fans out there, check it out.
Tip of cave splunkers. Try to avoid the monsters as much as possible. This is go down as far as you can, not kill everything you cam. The only reason to kill is if the monsters are in your way, or if the monsters are guarding chest.
Tip: To make the game a little less repedative, when street sweeping, work one week, then rest at home. It seemed easier to me to just work, rest, work, rest.
I love the fact that you don't gain stress when your moving around in the dungeons but i think it's stupid that you cant choose the type of attack you want to attack with.
