Is there an increased shiny chance or did I just luck the hell out by joining a random rare roselia raid and it being shiny?
Anyone have a drampa, eiscue or appletun they can trade me edit: Nevermind in the appletun, just caught one in a raid
I found easiest thing to do was talk to them a lot in the camp and then give make them curry a few times. If the curry level is high enough, it also improves friendship.
