Inferno – “A fitting image for you” [Campaign 5, Mission 2]

I can't seem to beat it either; I can pass it on normal difficulty, but on hard, I get wiped out by a single Necromancer, and sometimes a human shows up on week 2 and defeats me. What skills did you upgrade, and did you choose "Path of Blood" or "Path of Tears"?

Also, why does he have so many summons and only 3 level magic spells, even though he's a Warrior?
