Has anyone played the Mixed Campaign mission 1? Is it possible to get any reinforcements? There are so many battles and my units are thinning with each one and yet the battles are getting increasing difficult. Anyone has any strategy?

Leave the units you are supposed to kill alone.
The only fight you should be losing troops in is the one with the druids. I've lost 7 blood maidens there.
After that just explore and don't engage any troops that can kill any of your units.
You will find a certain artifact that will help you a lot .
Also try to get max luck and the destruction with the secret of destruction ability. Also try to max sorcery.
I've finished the map on heroic after one restart ..

Hmm, thanks. But I realize killing all those units was just a secondary objective. But what artifact were you referring to?

The resurection scroll .

okay found the ressurection scroll but still can't finish the god damn map...where do i gotta go to end it plz !!
