[Walkthrough] Necromancer – "Invasion" [Campaign 3 Mission 3]

Nope. Light and summoning. There's no darkness in the cities of mages, and I didn't bother. Isabel was a god of resurrection, so to speak. Railag and Markel were my dark heroes. Aglael is a chaos hero, Isabel and Godric are light heroes. Zehir is a summoning/light hero, Duncan and Frida are light heroes, Ilaya is a summoning/dark hero. Ornella is a powerful summoning hero, Arantir is a dark/chaos hero, Wulfsten is a summoning hero. Laslo is magic-less. I think that's it. Oh yeah. Faydaen. He was a summoning hero.

I rarely level up dark heroes.
