I've been looking at this and experimenting at how good it would be, I made a couple builds and overall i do like it. I just wanna know what others think.
I really like a Black Blooded Blood Conduit NPC I had with Blooded Arcane Strike, Spiked Destroyer, and Rhino Charge to break action economy a little bit. So, yeah, I think it is perfectly viable to build a successful grapple/bull rush character using Blood Conduit as a chassis.
