So, at level 5/7 two satyrs hits for 8,1k each... so 16,5k HP must have with 50% light dmg reducer!
I wonder how hard hell is then :/
EDIT: Got through it with 2 rev.pots with a healer, 2x 7*HP, 6*HP and a red panzer and 50% light damage reducer helper.
Boss hits for 5152 every second turn... and have around 23k defense !!!
EDIT #2: poison, auto spin with 5coins and sit back.
(and at the end I got my Faith with the second try =)
