Darkrift is pretty much correct. We were killing the PHs while waiting on people to gather. On the 4th mob or so it popped. I mean, who expects despot to actually pop that quick?
That was actually my second time getting up. I had 125 MP left, and it was coming after me. Figured it was worth the shot since it was at 1%.
(I was solo due to dropping PT to invite someone who offered to help us finish it off.)
