I'm hoping summon Lamia's will be very impressive with the high nature and the Naga's special ability of getting more. Are Lamia's sacred or is that just my memory being hopeful?

I don't believe they are sacred, but I *am* sure they are cold-blooded. A point to consider.

One of the big questions is what to mix in to the giants as small creatures can occupy the same space as a giant making up for reduced number of attacks per square. Winter wolves were great for this in Dom1 but not so easy to get with this race early.

Consider Manikins to mix with the giants. Since you're concentrating on construction anyway, they'll give you a good way to use your nature gems.

The Herses and Jarls are also very effective.

I agree on the Herses - especially with the bless effects you've managed to get. I've never found a good reson to build Jarls though. They're a bit better than the Herses, but much more expensive. And the Godes have the priest power for Sermon of Courage. How are you using the Jarls?
