I can't believe I finally beat this bitch! It took me 8-9 tries and I was switching up runes, weapons, gaining levels and health. It was madness but she is finally behind me. I really shouldn't have missed that visceral at 5:17, though.
It was funny because the first 2-3 times I got her down to manageable range after doing viscerals but you know how it goes in Bloodborne... one slip up and that's all she wrote!!!
