Confirm, does the Necromancer hero's ability to raise corpses extend to units of other races?
I'll check it myself in a few days.
And it doesn't work. When playing as the Alliance in a campaign and joining with Mermaids, the racial ability cannot be applied to them. And even when summoning elementals as a Necromancer, you cannot raise the killed elementals with the racial ability.
And so on.
But YOUR STUPID computer primarily kills the actual unit in duels, not the reinforcements, and the reinforcements disappear after that.
The stupid computer kills whoever it wants to kill, and this is not dependent on reinforcements. For the Alliance, it kills Griffins, and for Inferno, it kills Dogs. So, attach reinforcements to them.

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!
