Yes they made job. Most mortal wounds came from spells and i disspeled them mostly. Kroak did great job. Enemy could make me 3-6mw per turn and not in every turn. Skinks went for screen for impact of charge and help my guard pile in. As soon as my turn came they were 3+/3+/redn 1 reroll failed hitrolls and dmg d3. Anything came for my line was smashed
He had 2 units of flys, fat guy 30basic unit(perfect for that spell) wizard , wizard on that spiting beast,plague lord and 2 units of that mortal ones with 3 health. Of course he healed every turn a lot but it wasnt enough. Only thing that was dangerous for me were quicksilver swords on mortal realm.
Good thing about eternal starhost is that enemy have to spend mortal wounds for them and it keeps heroes alive. The most important thing should be killing heroes in every game in my opinion.
