So this is the best for us so far. I have no solid evidence on the 12 deaths, so believing it or not is up to you (hand took out 3, then took out Cetus again ). Screenshot was taken after everyone switched.
Gonna try to beat it today, so come on CK, Trolls and DnT, log your best!
EDIT: party setup was: 4 EIN monk, spellsinger, arti, shiradi monkcher, kensai AA, kensai, sorc, fvs + cleric healbot - it was finally about the perfect setup I can think of. We used 3 shrines (and no sp pots iirc - at least not the healers).
