On the other hand, there's no need to worry about whether or not to take perks for ranged attacks.
It seems to me that at level 15, the Inferno Fighter becomes very dangerous, especially with the right combat perks. Of course, the level of danger is directly proportional to the amount of health they had before.
Oh! And now I'm thinking, if this single unit is a Lilim, then the enemies will take reflected damage in response. How much damage is reflected? Doesn't it depend on the size of the stack?

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!
