Development of a Necropolis mage hero

I've encountered this setup in duels. It's easily countered by Alliance crossbowmen, Demon Destroyers with their aura, and Orcs with magic immunity (Tears branch).

This one is a matter of preference.

I'm curious, what makes Strength scary against magic for Necromancers? :)
There are essentially no targeted spells, Stone Skin doesn't remove it from undead, maybe the mass weakening effect wears off faster on Barbarian troops?

I've encountered "Tears" Barbarians, the funniest thing was, I quote:
"

, I thought the second skill could remove the slow effect (of the water elemental)."
The combination of Stone Skin and mass weakening turns Barbarian troops into weaklings.

It's more difficult with Alliance crossbowmen. But it's solved by summoning elementals and immediately placing them in defense. -50% incoming damage from the Spirit ability + a lot of HP and defense = "hit us, knights, hit us."

In general, until Necromancers are nerfed, duels are one-sided.
