Did you get killed by the Three Sisters?

I got killed, even with the Gold Bone, but I killed them on my second try.

Now, I don't even break a sweat anymore, thanks to red pulses, super poltergust, and dodging.
 
I've yet to die in the game (I got close, though, when I fought these ghosts for the first time).
 
I was beaten because I already had 50 health from getting hit by bats all the time. I lost barely any health after the gold bone was used.

I took 30 damage when I retried it for the gold rank.
