Magistar
Auto-translated
It wouldn't hurt, but this set is actually nonsense, it creates a clear imbalance. Yes, it's difficult to assemble, but it's quite possible in the late game, and whoever assembles it gets a huge boost in level 7 creatures and effectively wins against an opponent who doesn't have the set. The main thing is to take protection against mind control (vampirism, antimagic, skilled dark dampening on the Orc) and you can start dominating.
