The Chosen Ones

Not that hard just use galeoth(with omega set, ice diamond, and mana shield) or phodom with heavy hp and regen to tank all the attacks while fradz attack from behind. The only thing you need to be careful of is the charged wave attack. The other attack just not enough to kill your heroes in one hit. Cast amulet of bless to galeoth and seal of ressurection to fradz and heaven's bless to phodom. So even you screwed up you will be resurrected. I have lvl 5 resurrection combat kings for all my heroes so not so easy to died.
