The most comfortable and uncomfortable opponents for the Stronghold.

They already have plenty... maybe even too much. I saw someone messing around with Orcs... a hero named Arantir, I don't know what level, but with a Phoenix, Avatar of Death, 150 archers, 10 vampires, and groups of 5-6 Spectres. The Orc army was huge, 450 Red-Eyed Cyclops under Berserk (skilled). They took out their own first, and then died under constant resurrection and summoning of air elementals. Skilled Dark Magic was doing wonders... or maybe it was a cheater or a very skilled player. I found a video on Yandex.
