I accidentally started in Normal with my lvl 49 Conqueror (not the first time I've done that) and I decided to kill Hades rather than exit. My conqueror has never had problems with him (even the first encounter was fairly easy). However, this time he shield charges in, cast battle standard, then somehow dies. He heads back for revenge, watching his HP ready to drink a pot and again instant death.
So I read on on Hades attacks in his first form and they seam to be mainly physical with some vit (toon has 88% vit res) and HP reduction. My toon heads in a third time expecting to die again but Hades is only taking off a few hundred HP per attack. After a few more test runs I notice the shadow star attack hurts for about 1000 HP, but that is a far cry from 4800hp. So how did I get owned?
