"Necropolis" - changes to creatures of levels 6-7.

I, personally, was just playing with Harbingers – they’re great for taking castles. The nearby paladins and angels run around in circles and skip their turns while the rest of the units leisurely deal with the others. However, Banshees either attack with a fear effect (but only on one unit) or use a purely damaging spell, but the damage doesn’t always help that much, even with such a spell.
But on defense, Harbingers, as I said, are useless – one hit from Iris Griffins = -a whole squad.
