I was wondering what everyone's opinion is on some good inventory management tips? I've been trying to resist keeping all my Evo Mats, but now that I'm grinding T5 and higher dungeons, I'm getting more than my fill of higher tier materials that I just don't need as much. Since I've been trying to raise skill-up monsters, I've been needing more of the low-tier materials as well.

So how many do think is reasonable before you make a cut-off? 10 each of each color of the regular 'lits and masks? 5 each of the colors of Dub'lits, 5 of the Demon masks and a few of the Carmine masks? Not counting the Keepers or Dub/mythlits since I can usually get those pretty easily and get by well with just a few of them at a time.

If you get too many of something, do you think it’s better to sell them or use them as fodder? Or do you just keep increasing your inventory box space? The latter option is tough since I'm trying to save up some stones for a GodFest or the DC Collab. (T_T )

TL;DR - Inventory management tips, please. Surplus Evo Mats? - Sell, Fodder or Stone-up?
