What kind of magic do you like?

If I'm not mistaken, the Banshee no longer protects with a level 4 spell.

They cannot be resurrected forcibly, i.e., by opening their spellbook and resurrecting them, but after death, they are automatically resurrected. Of course, antimagic has no effect on them.QUOTE]

Phoenixes can always resurrect themselves if at least one dies. To do this, you can always go to the spellbook and resurrect them "forcibly." With antimagic, they automatically resurrect after the entire stack dies. It's good that they resurrect somehow even with antimagic.

Dr Motor;206041You can't break antimagic with anything at all. Spell steal and magic shackles probably won't work either, as they also need to be cast on the target, and if they are under antimagic, you simply can't cast them.
Isn't that right?

They can.
The description of Antimagic on the Heroes of Might and Magic website is: "the target gains immunity to magic for the duration of the battle
Features: when Anti-magic is cast, it acts identically to the Dispel spell; Anti-magic does not prevent the spells Town Gate (only if it is not cast on the hero using Town Gate), Stun, Binding, and Smoke, and increasing the stack of created units using the corresponding spells of the Summon group
Possible errors related to the spell: Anti-magic does not remove the spells Poison and Plague, and the target continues to receive damage from these spells
Also present in the game as: a property of the Black Dragons units (n/a)."
I don't see anything similar to what you're saying.
P.S. Kind people, maybe someone can clarify an interesting situation :).
P.S. 2 Maybe we have different versions of the game? I have 3.0.0.2.
