Why do i need to explain this... Just don't waste time on max this unit 😭 (I just do it cuz i have nothing to do in game, just waiting for Snowdin update) About Trait, Kindness / Integrity or Bravery... up to you guys chose what is best for him.
I saw the text around upgarde 6-7 and if you are bored of this game you could try out this one ut soul ops like game ive been adicted to. Its called "undertale soul ops aus destrution" its a very underrated game for how good it is (also cause i cant figure out how to do the sercet j encounter)
