Why do you take Mentorship? Necropolis has so many useful skills, but you're filling up two whole skill slots with practically useless ones. I understand that you can develop Chirgeys, but you won't scare your opponent with a Chirgey, will you?
But you can scare your opponent with the size of your army, which will increase dramatically if the Necropolis has 5 heroes of level 12-15 with Skilled Necromancy, because there will be much more Dark Energy than a Necromancer without Mentorship...
Горящие реки сходили с ума, пытаясь остаться водой,
Земля пропустила коварный удар, раскрывшись на шаге вперёд,
Взлетел разъярённым драконом Огонь и понял, что тоже умрёт...
