I just upgraded my Corbett to lv100 and maxed out everything and it did get faster, I think I will need to save a lot of centies and they're my real gate, after saving for so long I still don't have enough of them to max out my first lv120 unit aka Corbett. Or did I farmed all the wrong place ? Recently I focused on farming Memory Dungeons, and they give pretty good rewards.
I don't know my turn 1 team can't even do anything in EX, probably need more investment but I don't think they are very useful for me compare to Corbett, and Valentine Knotweed, she turned out to be really good. I think slowly I will move on from turn 1 team and focus on something else, maybe a skill drain team.
I'm not sure about equipment upgrade, and currently that is my final source to squeeze even more power for Corbett.
And I saw a lot of posts of this blogger showing off personal weapons of Corbett and many units, is it possible for me to get those weapons ? https://dororon-fkg.blog.jp/archives/19411673.html
