It should be noted that the ranking of the farms are not based off entirely the calculated efficiency, as ease of the farms and the amount of time is factored too. All farms can be classified into active farms, meaning the player has to constantly kill enemies to be rewarded, or AFK farms, where the player can leave an auto clicker going to reap rewards. Each location has its own number of enemies that you figure into these equations. Drops includes Upgrade scrolls, weapon/armor drops for crystals, and accessories. Farming can be classified into three direct groups: Vel, Drops, and Experience.
