Cursed

I started playing on a hero. The starting maps are well-balanced.

After taking the catalyst from the demons and turning all available souls into 60 Fire Elementals, it became much easier to progress.

Getting to the camp was straightforward. After the camp, it became much easier... until the underground. Only the Inferno creatures caused trouble, when the Imps drained mana. I had to think a bit.
Question: Is it normal that wolves summon more wolves, then we cast Phantom on both of them, then the phantoms summon... and you can fill the entire field with wolves endlessly. Is this some kind of cheat?)
If you take our Battle Spirit and maximum Initiative + Synergy and Sorcery + artifacts that suppress the enemy's Initiative = it will be approximately like that.)

which I cleared without losses with 100 Fire Elementals and 20 Mummies.

I had 70 Elementals, 61 Wolves, and 10 Mummies. I always placed the Mummies so that they would resurrect themselves while I was casting the summoning spell, and depending on the situation, I placed Wolves and/or Elementals. I went into the dungeon with 10 Mummies, 71 Wolves, 100 Elementals - not enough for the curse)). I'm thinking about how to split the souls to create either Death Knights (Deadly Strike and Ravage) or Phoenixes. And I need to level up with a mentor - the question is whether I have enough money or not... I need to sell something
