On any previous month for at least the last six months, the harvest of the Element Farms was merely a daily check-in plus a little bonus.
William's most commonly used Elements at the time were Fire, Illusion, and Space, with occasional usage from about a dozen others. Until recently, he only had enough Farm Slots to grow these types of Elemental Fruits.
Elements such as Darkness, Poison, and even Time were purely supplemental as opponents rarely required him to use Magic at full strength. It was a sort of "one size fits all" strategy.
If one fireball wasn't enough, just use two!
William knew he wasn't using his Magic to its full capacity. Only a thousandth, or a hundred thousandth of a percent was more accurate. But to conceal his strength more effectively, he rarely made use of the Mythic Elements Order, Fate, or Karma.
The Ascended Realms were vastly different, though. Sooner or later William would be severely punished if he ran into a true expert during his travels.
