Oh, nice. That's one of the things I'm thinking of doing as a challenge run once I finish NG+, where I just about an hour ago killed the Four Kings myself and became a Darkwraith. They're such a pain in the ass on NG+, I had four attunement slots for Pyromancy and ran two copies of Combustion and Great Combustion, but even that wasn't enough to kill them and I had to wail on the last on with a weapon. There were three up at once when I killed the last one, and I almost died to a ranged magic attack after I got the last hit in. :lol
