So me being the moron that I am assumed that I could just buy the extra AC needed for the campaign after rolling for the set that I wanted from the AC gacha... But it's actually impossible to buy any, so if you somehow don't have enough AC because you were stupidly rolling for that gacha dopamine, you're screwed.
You've been warned!!!
I sincerely hope that whoever decided that the reward comes from "buying AND selling from the personal shop" gets punched in the nose.
