How do you fight the Niefel giants?

[Nikelaos]

fear won't work most of the time, nature bless gives beserk.

iron bane sounds a good idea and it should counter an earth bless, life drain would have it's work cut out especially with a nature bless though, i think a barbarian spam + iron bane would be a good idea, also how about sleep cloud beat em at their own game of fatigue, just make sure you have some chaff to hold em back - markatas and hoburgs anyone?
