Necropolis – “Misfortune never comes alone” [Campaign 2 – Mission 1]

Out of all the missions in the Necromancer campaign, this one is the most challenging, as you initially only have access to 3 types of creatures, and even those are without upgrades. The computer, however, has 4 types of creatures and all the upgrades!

As an alternative, you can leave the towns untouched (not rebuild them); this has its own advantages and disadvantages (but it's an experimental idea):
Advantages:
-In the end, you will have access to Guardians, Archers, Novices, and Griffins (the possibility of upgrading them depends on the specific town).
-There is an upgraded market (the undead don't have one at all), which means you can buy artifacts.
-Archers do not have a range penalty.
Disadvantages:
-You cannot replenish your own forces, BUT you need to preserve the initial troops, as the plot requires the troops to be replenished with undead. However, a mixed army is a problem for human troops, as there will be problems with morale.
-Necromancy only works on undead.
