I am using the necromancer and I am now having great difficulty in dealing with the cloud citadel.

There is a queen of cloud with tens of air elements and cloud warriors in the cloud citadel. Each turn my force would suffer more than 20 project lightnings and the cloud queen would release a spell causing blunt damage to every unit in my force.

I have tried gathering a force of mist warriors which is 100% shock resistant and ethereal. But they all died after three strikes of that spell. And most of my wizard died in the first two strikes.

I succeeded in conquering the cloud citadel using 3 ether lords with a spell that can enslave enemy unit and a bunch of ziz, dracolich and death knight. But the loss is too heavy that i can't suffer twice.

I think some monster with high HP and 100% shock resistance maybe helpful but I am not sure.
