A question for those who already beat the game, have you completed the last affinity mission of Elma?
I swear that was by far the hardest mission of the game, I just went there thinking I would be fine but I was so wrong. I even went as far as saying yes when I died 3 times in a row and the game asked me if I wanted to lower the difficulty (first time I had to do it).
Took some grinding and a ton of luck to complete that mission, but god damn was that hard.
