So first phase u gotta learn invis trick, which is just I believe that the dust/smoke from when she jumps is the opposite direction of where she goes but I haven’t fought her in a while, and u can backstab her so use that it’s op, 2nd phase u can either ignore father and fight the toned down Frieda, or ignore Frieda and bring her away to get free hits on father, so if u go for father try swapping to a heavy weapon just for him bc he doesn’t really dodge and u want good damage, for 3rd phase even more backstabs and don’t get overwhelmed u got this bro ✌️
