Which creatures from the alternative upgrade options do you choose?

Regarding Necropolis: 1. I take the new ones because they are more durable and powerful. If you get something like Battle Fury, Resilience, Amulet of Blood Claws, or Ring of Vitality, they become a serious offensive force. Also, if you get the Celestial Shield on level 5 of the tower, that's a great find. 2. In principle, there isn't much difference – zombies still have the same role: to be a punching bag. The new ones can take more hits and reduce morale, while the old ones hit harder. I usually take the old ones because the weakening effect stacks, resulting in a more powerful effect. 3. I choose the new ones because of their stats. There's practically no point in taking the old ones anymore, except maybe against mages (although by that time, they hardly have any mana left). 4. I'm all for stability, so I take the old ones. I think the new ones would be good to combine with Soldier's Luck and/or Mass Expert Dispel, but I haven't tried that yet. 5. It's a very difficult choice, but I still lean towards the new ones because they allow you to minimize losses. However, if you're fighting hundreds of liches, the old ones will be more useful (but not in battles against undead, of course). 6. It depends on whether you get various artifacts, such as the Cloak of Death's Shadow, Ring of Broken Spirit, etc. In the case of low enemy morale and good defense, use Banshees (they are more durable), and the rest should be Messengers. Also, Banshees have a skull instead of a face, which is a plus for them =). 7. To be honest, I don't understand how Death Gaze works. Does it reduce morale after the attack, or does it affect everyone at the beginning of the battle? For now, I take Astral ones because they deal more damage and have Sorrow. And a well-developed Necromancer can apply weakening himself, even in a mass effect, unlike Sorrow, which only affects individual targets.
