The Quest for Truth

I've reached mission 5. I'm having trouble with the Earth Warden (Orc) - Sandro is leveled up in Dark Magic + Summoning. How did you guys deal with this Warden?

Based on my experience: Before the battle, double mana, +10% HP. First cast - slow or confusion (so that the archers don't hit hard and to weaken the counterattack). Then, depending on the activity of the Cyclops: cast Berserk on them, let them hit their own, the main thing is not to let them break through to your troops. First, you need to eliminate the leaders so that they don't speed up the Cyclops, and don't forget about the Wyverns and Earthlings. When only Cyclops remain from the attacking units, take control of the Warmongers and the Earthlings, cast mass slow if it hasn't been cast yet, mark the Cyclops, use the Hive to stun them, mark them again, and use Raise Dead with Vampirism to restore the number of your troops. The main thing is to have good defense. Something like that. A very unpleasant enemy due to the summoning ability. It also depends on what your fifth skill is leveled up to; it's good to have attack with Ballistics, mass haste, and tactics.
