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

If you have moro dark, then you can replenish in crosswordls your undead troops by a few ways:
1. Moro dark convers knights into black knights.
2. In Montero you can also get them from Mesmer, unlimited ammount
3. Dark mistikus gives you Necromancy staff (or whatever its name was) after you complete his quest. It converts peasants into skeletons.
4. Moro dark can convert skeletons into skeleton archers.
5. Cursed ghosts replenish themselves.
6. Training academies allow you to train archmages into necromancers.

So basically only Bone dragon and Ancient Vampires are a little more difficult to find. Everything else is pretty easy.

I've always hesitated to use any of the two ghosts in my army, precisely because keeping their numbers in check seemed like too much to bother with. Is there any relatively painless way to do that? I would like to give them a shot.

Well, the easiest way is to get them into the thick of the enemy troops and cast Target on them. Then sit back and watch the carnage... if it seems your Ghosts are getting too much of an upper hand, fire off a Fireball or a Lightning into the crowd. That's pretty much how I handled things as a Mage.

If you are not a Mage, you can try diverting your Ghosts and sending them against enemies they cannot drain life from when they get near the Leadership limit. Ghosts are awesome Cyclops blockers - they have excellent resistance against their attacks and are fast enough to get there and block them.

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.

This is actually one of the many elements Katauri kept from the original King's Bounty, published 20 years ago by New World Computing. Even then, a player had to be very careful with ghosts, lest they go out of control.

Indeed, in Heroes II this was the reason they were not hireable units.

Thankfully though, they no longer turn to peasants when the Week of the Peasant comes...
