Strategies for Rezo battle

[goldenpath]

I had a lot issue with this fight too when I attempted @ lvl 35 viking with 15/14/17 (yeah..viking with higher intell!), tried few times and just couldn't manage, I do not have ice prison so the 2x stacks of 6000+ skeleton archers dished out way too many damage to my troops.

So I have to start questing and lvling up @ other islands, also got some gears upgrade, came back @ lvl 39 with 20/25/18 and finished the fight with almost no losses.

I used blind+ greed rage skill to control 1 stack of the archers, cast doom and focus fired on the other stack. Tanked other undead units with paladin+horseman combo. I had to put points into transmute and lvl 2 concentration to make sure I have enough mana to sustain the whole fight though.
