Also, I tried teleporting them "behind enemy lines" (thanks for the advice, Oxygen) - it's just pure mayhem. Not only is it not that easy to defeat them even without tactics, but with a poorly planned attack, they can accidentally hit other units again.
Development will be more challenging, but in principle, it's possible to manage, it just depends on what magic the guild provides:)
And in the final stages, there isn't that much benefit from the Djinns.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
