NIN buddy of mine solo'd it the other day NIN/DNC. Very easy from what he said. He's got Kannagi but that doesn't make the fight any easier, just shorter.
How did he handle that petribreath move? Just curious, I know Amaltheia is easy, I've duoed it Ochain pld and rdm.
Edit: and how about great bleat, the hp down move? I realize /dnc can get rid of it, but how much of a risk does that pose? Using a lot of tp to heal back to full?
