I'm rather in a lazy mood right now but you should all know the routine by now for advent battles.
And first attempt at gatcha and got Rapheal.
May not be that great of a SSR but none the less, a good roll for me since I main light. Might roll again just to try to get the SR.
As for the fight itself, I would highly recommend regular Amon if you have her. You do not want get petrified locked in this fight. That is the worst possible situation and can easily lead to a loss. Using Pheonix can help reduce the chance but not worth it. Though if you're using a light team or a strong team in general, you can take her down rather quickly and easily without the need of a healer.
