Witch of Hemwick (Easy??)

So, I'm replaying BB and I was about to fight the Witch of Hemwick. No big deal right? I've done this countless times. Except. For some reason. I couldn't win. Somehow, she (or her lackeys) always killed me! Like, with that stupid arcane grab attack that always seemed to get me when I was right next to the other witch and like, 3 shadow guys. But, that's not the point of this post. Eventually, I won. I was so relieved! I ran down to get the rune workshop tool when I stopped, 'cause I noticed something. I had full health… and all 20 blood vials. Did- did I not get hit?? That's… never happened before. I'm thinking I probably got hit and got it back through regen- but then again- it's really hard to regen against the shadow sickle guys. At least for me. Well, anyway. Maybe I'm actually gitting gud?? (Nah lmao)
