I've taken all of them down except Rom the Vacuous Spider...this thing is unbelievable but I'll get him eventually. I've also noticed the scene has changed from afternoon sun to midnight moon so maybe the night has an effect on the enemies..and arcane/frenzy being used more by enemies. Last night I made two mistakes...I went to Cainhurst Castle and got my butt handed to be royally then went to the Nightmare realm and immediately turn my butt around...don't go to these areas unless you're leveled up.
I finally got some elemental effects on my +6 spare saw.
