Is Necromancer the most powerful and versatile unit in King's Bounty series?

[Autoclave]

Target is very good. Yeah, sometimes it's a pain in the ass, if they drain too many souls, they might even become actively hostile. I had to reload a few games because of this.

However, target and necromancer AoE attack are good things to keep their numbers in check. I enter every battle with 20% less ghosts then my max leadership.

They had to add this drawback to ghosts, otherwise this would be one of the most overpowered units in the game.
