Dear Vulture
At last answer i wanted too hear,actualy i expexcted that
Thank you for advices and long post but i already know all of that.
Also i finished the game quite easily without that

My love setup :
emerald dragon - mana mana nice damage hp
shaman - heal distract quite high hp - could put inquistirs here but i had only few of them in my game and sacrifice in lotd and i got used to shammys so much that i didnt think about changing them

hunter - ale barrel + telscopic sight
elf - ale barrel + telescopic sight
royal snakes - frog feanora + ring of snake king
and powerful spells ( playing as a mage) slaughtered every enemy ( for overpowering/impossible enemies had to play fight twice to find the best strategy to win with no loses ) without much problem ^^
I was using reaper abilities like hell just to got him lvl up , got lvl 3 timeback after beating up Karador and so started using it for royals/elves .. lvl 4 i got at last fight before haas .. lvl 5 never came .. but Haas .. armageddon armaggedon end of fight
IF i would like to fight him without arma i guess i would have to change setup and get rid of archers because they wont do anything when you start in the middle surrounded by so many dragons , archdemons ,ents,cyclops
