Necromancer – “Invasion” [Campaign 3, Mission 3]

In version 1.5, I completed the "raise 1000 skeletons" task faster than in 1.41 – immediately after capturing the 3rd city. It seems that not only skeletons are counted for this task. And that's despite the fact that I tried to avoid fighting strong heroes emerging from the portal unless absolutely necessary, and instead focused on cursing at least one city as quickly as possible. The need for a fight only arose once at the beginning of the game when Hafiz didn't even have titans. Therefore, I haven't had a single serious battle yet. The army is clearly stronger than it was in 1.41.
