After many tries, i got the doomed hero badge with only 2 conjurers (full Endurance - no need for int with summons) Full equip was runed item of Endurance. Did not quit properly though, never gave it to me! blah, oh well, my fault.
not complicated, and as hard as you want it to be, a little repetitive. Like the new classes, but the conj seem a a little overpowered. I wish there was a score bonus for using less characters in your party.
