I had some problems with Zangetsu, had to restart his fight about 10 times, finally beat him. Every other boss for me has been a max one time restart, no problems ever. Then I got to Bloodless. I was worried about the bosses being pretty easy, being a big Castlevania fan, and after about the 30th restart, still getting my ass kicked, I said "Yeah, this is great, this is more like it."

This feels like a massive power spike in the bosses that I have faced so far. If she is super difficult, should I be grinding and doing other things right now? My strongest weapon is a club with attack 30, I am hitting her for 29 per hit. The farthest I have been able to get is the second time she casted Blood Rain. I watched a guide video and the guy was using the pillar of spikes attack on her when she was still. I am using the knight familiar which seems like a no brainer. But I guess I don't know what other shards I should be focusing on. Is this something I should just figure out on my own, or is there an "in the know" I need in on?

Thanks!
