What does DRW do defensively?

Is the only thing DRW does defensively is the parry plus the quick Bone shield stacks?

I found out the blood boil plagues don’t give you extra health and death striking doesn’t give you more blood shield. So besides mimicking abilities for extra damage and threat there is no other defensive things it does besides what I mentioned above?

It mirrors your attacks kinda like mage’s mirror image.

With the extra attacks also comes extra RP which is great during heavy damage intake to get more death strikes out. Doesn’t feel as impactful being that blood shield actually does something to smooth out damage intake now but it’s still nice.
