You're basically trading in your free battle cubes (the blue boxes) that you get each hour for the battle cube recharge you get when you are the finisher of a battle. So wake up in the AM, finish off 3 bosses, farm 3 cubes. Log in a few hours later and do the same thing, etc. Seems like a slow process, but the cubes can add up.
