Which hero do you like best in Heroes IV?
1. Haven magic seems more neutral.
2. It doesn't summon creatures, so you don't have to think about which one to summon (a wolf, a fairy, or an elf, for example).
3. It has some kind of neutral effect – increases attack, increases defense.
4. You can create good spell combinations.
5. It can harm the opponent, but not only (unlike Chaos magic).
6. And the conclusion: unlike other magic styles, it is somehow more balanced and orderly.

And what's good about the Necromancer? He only spoils everything for everyone and doesn't help himself! Except for the "Sacrifice" spell. Although even here, you spoil your own army and help with negative consequences. Well, only "Demonology" increases the army, but even then, only with Nature magic.

Многие их ищут, многим они вовсе не нужны, а многие даже не замечают их, не понимают что они вокруг нас, каждый день, везде.
А эти чудеса порой, сокрыты в обычных, привычных предметах.
What’s good about the Necromancer? He just spoils everything for everyone and doesn’t help himself! Except for the "Sacrifice" spell.
But you definitely need to think; there’s no dilemma here about who to summon: a wolf or a fairy; an elf or a tiger; a griffin or a unicorn, etc.

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!
And it's better not to think about summoning at all, but just summon mantises.

It's better not to think about summoning at all, but to summon mantises instead.
In my opinion, it's better to cast Dragon's Might on the strongest creatures... or, if you have a good number of them, use it on griffins – they'll deal serious damage to everyone.
And there's no need to level up the Death Mage to level 5. :)
