I played for 10 hours non stop from like 2AM. Didn't go to bed, didn't sleep. I couldn't stop. I endlessly grinded this fight and I finally did it. I was so tempted to cheat, but I felt like it was possible. That was the hardest UT/DR fight and I did it on patch 1.1. How did ANYONE beat this birb on the OG patch? The fox was so easy compared to her.

I think most people can agree the bullet patterns and balancing is kind of BS at times in this game, but it seems like this battle is more of a slugfest with the added HP recovery feature, so I can forgive it. What an insane boss.
