Best level 6 unit.

The point of this is HUGE AND FULL-VALUED!!! Just imagine, all monsters are level 7... And as for morale, Archangels don't get in anyone's way, and adding them to the army is definitely a "+", not a "-"

Yeah, units from seven Castles mean -3 to morale; well, let's say +1 for archs, so total unit morale is -2, and if there's undead in the army, then -3. You can only mix two Castles—elementals and undead; you could throw in minotaurs and angels with them, but no more, imho.

The point of this is HUGE AND FULL-VALUED!!! Just imagine, all monsters... with fire immunity etc.

And what for? It's countered elementally, by the same chain lightning. Besides, you won't find 7 such units.

Generally, imho, units should be compared based on the criterion "Usefulness for their own Castle; how harmonious a unit is with the rest of the Castle's army."
