The weakest castle in Heroes of Might and Magic IV!

Yes, Chaos breaks through with its combat spells. But it also has its drawbacks. First, there is no spell to remove enchantments. All curses remain on it. The Dark creatures are, of course, protected. But what if Haven casts hypnosis on Efreet or Hydras?

I agree, and you can't resurrect him if the hero has life magic, and besides, Haven magic is more interesting with its combinations of tricks for enemies, not like Chaos, where there are only combat spells with some blessings: like cat attack (or whatever it's called), confusion, but it's also more difficult to apply Chaos magic blessings to black dragons.
