Honestly super short, wish it had more bosses. But Sister Friede is one of the greatest fromsoft fight ever made. For me not super difficult but totally understand why some would have a hard time with the fight especially with the fact it has 3 health bars, but the fight is super fair, I guess second phase is the annoying but once you learn Sister Friede mainly just does the ice move if you keep distance and also priotize Father, but if she goes and tries to heal than punish her.
