Kallus 2 - am I building this right?

I am currently running K2 in ravens and T1 in Children, so I have no direct experience of the K2 Children, but extrapolating from my experience, I would say that the list above is very solid but you need the fury management. Azrael is going to be rocking 4 fury every turn you do something with him, the bolt thrower is probably also maxing out so that is 7 fury to deal with before Z starts swinging.

The other big issue with this list is you may struggle to score rectangular zones as your battlegroup is probably going to want to stick together so I would like a harrier as a quick low commitment piece to go and score the zone your swordsmen have cleared out. Spell martyrs are also pretty important as Battle Lust is only range 6 and you are going to want to be handing that out nearly every turn.

I would say you want 3 shepherds and 2 spell martyrs and then either Annyssa and a 3rd martyr or a harrier and sorceress for free charges on A and Z.

No more beasts after that.

You want another unit. I'd suggest Swords or Raptors.
