There are goodies like the "Golden Table" which gives +10% gold from battles, the "Red Carpet" which gives +4% gold from battles, and the "Royal Wall" which also gives +10% gold from battles. There are also numerous accessories which give +X% gold as well as consumable goodies. Farming for gold is actually very important, and if you are looking for a good place to do that, you can head to Farm Village which has scaling scarecrow enemies which, as you level, give increased xp and gold as they level. Stack your gold farming tools and get to work; 9,001 gold won't last you for long.
