Necropolis versus Academy.

Counterspell might not help: since the army of Cacodemons has Warlocks... It’s better to take “undead protection from magic” from the Armory, and not only from it (besides, we’ll have to take “secret knowledge” there, which will be very useful for the Necromancer).

Luck is hard to get: the probability percentage is only 2%. It won’t decide anything (however, it’s tempting that our units’ abilities will work more often if we take “Soldier”).

It’s better to take defense instead of attack. We need damage reduction in defense. We take either the Stone Skin branch with Solid Defense or the Reflection branch with Dodge and Damage Prevention.
