Just beat the 2nd boss, Father... this fight is rough but if you
it makes it sooooooooo much easier:
move the entire fight onto the stairs
The hardest part about this fight is dodging his attacks while maintain visuals and not getting blocked by gravestones. If you traverse up/down the stairs you can easily see him at all times, dash out of his attacks, wait for him to exhaust his combo and land a R2. I'd hit him at the top of the stairs, middle, and then go back top.
Once I moved the fight to the stairs I beat it on my 2nd try.
