I did a shout a while back and got 6 of us into there. At the end of about 2hr, 5 of us has gotten the spell while 1 didn't due to skill being way too low. We also did pick up 1 JP BLU dualboxer there.

I do recalled he uses Bloodrake throughout his HP range because he has used it as first TP move as well as near deaths. I tanked him mostly just using genbu shield + eva sword while others just whack him on low dmg club/dia, etc.
