Running a devil team for dark knight. I wish I had a couple of decent devil orb changers...
Dancing-hera-ur, permafrost hera-is, ultimate devil Luci, King baddie (used twice on fenrir and last level), and finally an ultimate dark hera. Paired dancing hera with beelzebub, extra HP helped considerably.
I ran the mythical version, so I stoned (garaunteed monster and had the chance for a skil up on archangel michael, and fenrir knight) got severely orb trolled on the grips rider fight. Then saved orbs during the final level and had a couple of lucky darkness blocks.
I'll run legendary tomorrow probably, rest of my stamina today is for a light orb...
Water/Dark Vampire works for this dungeon. One of the few times he's better than regular Vamp. Also Wicked Lady even though her stats are poor. I max skilled one since I don't have Persephone.
