Just did this camp... took about 30 hours before I was able to get the box to drop. Saw this guy well over 10+ times. He definitely does not drop the box every time.
I had planned to take screenshot and upload since there's not one here. But by the time this guy FINALLY spawned, I was dog tired and just wanted the nightmare to be over. Bard had the camp when we got there, he had killed 4 ph, He decided to leave and let us have it. We had to kill TWELVE more phs, 22 min each, before named showed up. Yeah, I REALLY wanted that box. Good thing he drops the box every time. If you go after this guy, be prepared for a long night. ChantressClio
