any Legend item that has Fortune Skill, Luck, and Gold Find are good for getting a good start on a Farming build for any class. Normal to Epic items that you find with, or craft with crystals, that have those 3 will help you with Farming also. but since you are putting those farm affixes on your items, that is fewer spaces for defense and attack, so it is a balancing act. later on, when your Farm build is bringing in a lot of loot, you can start searching the Forums for Farm Builds that help farm for Eternal items, Legend/Crystal items, Crystals/Myth Stones, Experience (if you are Ascending for Perks). what I did was just Ascend for all 6 Perks, and along the way, I learned better ways to build a Farmer, and also how to craft a better Fighting Build that can survive with a little Defense Crafting along the way.
