MetallicBoy, "Mundane becomes extraordinary" altar is most useful of altars. It makes perfect item from first _white_ item in your inventory. So, have white weapon or good armor, and dispose all other whites. I am happy then I see this altar and always save white bow in my inv.
It does matter only if you play Attrition mode though.
Zwischy, I use my cleric usually in a back row, because there should be only one tank, or it will be waste of HP.
And he wears heavy armor, because we have foes with ranged attack and I need cleric to heal others, not self. Not as heavy as need though.
Oh crap! Got to Corruptors level at 338% and had everyting to win: 200+ dam on weapons, 63% on tank etc. And dead by own mistake =)
The best party seems going to be Warrior, Cleric and 2 Rangers. Warrior has damn powerful skill Defiance, Cleric is a must and Rangers both good attackers and defenders. Pin is the best skill and Focus must have in tactical mode. Balm helps a lot.
Doomed heroes is easiest badge. Just use permanent skills, such as Inspire, Adrenaline, Balm, Swiftness. Dont' forget to restore spells on your char after death/rewive. Don't kill last monster in a wave, just pass and let your party full regen (save weakest monster for it). That's boring but helps. That's all. I've got over 80 and got tired.
The most difficult modifier is Attrition.
With buying ability it's piece of cake. Without it you're in trouble, found yourself in way outdated gear. Front line need at least 40% and usually have less than 30. Then meet horde of greenskins and die in a few blows.
