So, this is Demonology, which you denied in your previous post.

I didn't deny it. I just defined a different application for it, which, in my opinion, is more rational. That is, not to intentionally recycle as many of your own units as possible, but to replenish inevitable losses; the difference is obvious.

I'm not a master of demonology, but I think so. There is such a concept - a strike stack - one or two thick, powerful stacks decide battles in Fortress battles much more often than a balanced army.

As an option. But you can also experiment with a large number of stacks - it depends on the tactics. In general, if you recycle everything that moves into a strike stack, there are too few opportunities for maneuver, including on the global map. In my opinion, it is better to form several detachments for attack - one, the strongest, with the hero, and others, weaker ones, from the rabble - to annoy the enemy, distract attention, threaten weakly defended lands and castles. In addition, the psychological effect may play a bad joke. A "swarm of demons" looks so threatening that hardly anyone would dare to engage them in open combat, and most likely they will have to break through the wall:smile35:

And what, are there no ways to remove the spell, for example, with flies?

There are. But flies are not found everywhere, only in the Fortress. In addition, this is a rather weak unit to include in the hero's detachment. There is also the possibility of removing magic with an expert, which is also quite rare. + the opponent may cast a spell before you...

This is Luna :D For two-keos units, the wall of fire is twice as scary.

Well. She would be even better with ifrits...:)

The main problems of Avern: weak offensive power of the army at the start

This is indeed the case, but this can be partially compensated for by hiring another hero - the best one is from the Dungeon.

and the "paidness" of demonology, in contrast to free necromancy,

Demonology is a form of recovery:)
