Necromancer – “Assassination of the Ruler” [Campaign 3, Mission 4]

On the map, there are 3 Necropolis outposts, 3 graveyards, and some other dwellings. It's dangerous to attack Cyrus when you have fewer than 30 skeletons, especially since titans appear at the entrance(((
Gather all the resources and buy troops; I personally didn't have enough neutral undead.
