Magic in Heroes of Might and Magic V.

Yes, exactly, there aren't such spells in magic schools, but they are still full-fledged magical spells. Not all of them, of course, but for example, "Scream of Terror" or "Wrath of the Horde" – even if they are not very strong, they are still quite magical.

They aren't magical at all... You wouldn't be scared if an orc suddenly screamed next to you, would you?:D And we'll consider the effect of "Wrath of the Horde" as the target squad's heart bursting from such screams... :) And what's magical about that? And if you mean balance, I don't think that one "Wrath" will replace magic;)
Now, about the topic. What do you think about that very "Scream of Terror"? Or "Fear my roar," as they write in pirated versions?:) The spell is quite effective at high hero levels, but to get the blinding effect, you have to spend it every turn (or almost every turn, with the Battle Cry skill:) You can roughly mock the most powerful squad of the enemy at the end of the battle. Are there any other ideas?;)
