Can you tell what the mobs on 2nd 3rd and 4th circle were? How hard was it overall?
WE've just killed Lich champ, imo it's much harder than the old felluca spawns, 3rd circle were undead gargoyles and some new undead mobs, 4th was skeletal drakes and doom (as far as i remember) wraiths. The champ itself was not that hard, no good loot so far for our party (though there were 3 other guys also, no idea what they've got)
