On my 2nd playthrough of 0.5 Asterion has a black shirt/vest with the orange Greek pattern, but on my last playthrough he had a pink shirt with 'Moo!' on it. Is this random or determined by dialogue? Also, I've tried focusing on exploration for Luke and Kota rather than Tech but they still haven't found any new clothing options for Asterion, currently on chapter 15.
So what's the deal? Am I missing something or is it randomly determined?
