It isn't the reverse? Ie Inquisitor refuse to resurrect Demons but you can with your resurrect spell? I don't remember well.
About Karador battle my last try took me many attempt before to succeed but it's weird I end in using an overall strategy close to my previous game.
Joined bellow a funny snapshot after few rounds. Notice where are the Death Knight, lead there by a common use of Ice Thorn and very mobile target with Red Dragon.
The second snaphot is some round later, still all army but Red Dragons at start place and Death Knights still wandering around the place.
This attempt had been a nightmare until I decided three things:
- Use Red Dragon as a very mobile target.
- Take care to have a unit with the higher initiative that cannot be hypnotized (Red Dragon instead of royal snake).
- Take care to always cancel a Karador negative spell on my units and keep my High Magic opportunities more for that.
Other more standard points was:
- Drayd with summoned Thorn to avoid Necro call.
- Reduce enemy stack before killing some.
- Use Ice Thorns to slow down enemy stacks.
- Use slow to control some stacks dangerous for my target.
- When killing a stack take care of initiative to be sure to have right after the death a Thorn ready to summon Thorn or a unit to walk apon the dead stack.
- Use few targets to reduce Necromancer stacks.
