Early Game: Adjust Enhancement Level and Initial Substats to your liking. In the early game, you may have to keep 3 & 4 Initial Substat pieces for sure otherwise you would have a lack of gear. Make sure to keep all gears with Speed as well because every piece will be important for the early game.

Late Game: Adjust Enhancement Level and Initial Substats to your liking. In the late game, you only have to keep 4 Initial Substat pieces to achieve the best results and by this time you would have too many gear. The filter helps to sort these out so that only the better 4 Initial Substat pieces will be kept. If it is too much, then limit to 3 & 4 Initial Substat pieces.
