I am trying to make a immortal vampire themed build wanting to focus on bloodsurge. I really want to stack my max hp for it and I have the build pretty much figured out in my mind (tho, still leveling and the damage is so low with bloodsurge in penient). My only hope is to find a way to scale my damage from my hp, I know there is a item that gives damage to skill but make them cost 3% max hp but I don't think that increase their damage by 3% of your hp. Any uniques/aspects etc I might have missed?
