Stronghold vs. Necropolis

Chingis, playing as a mage in the Stronghold faction doesn't make much sense, as they don't have any Primary spells, and there's only one unit that attacks with magic – the Stalkers. Cyclops' ranged attack also deals magic damage, but as you noticed, the damage is very low, so it's better to use them in melee combat (especially if you actively use their ability). I won't say anything about development, but ramzez's option looks viable in any situation.
