- Magic in Heroes 3

Has anyone used the "Forgetfulness" spell (level 3)? It's really cool. On expert difficulty, when attacking neutral creatures, none of the archers shoot; they just attack in melee. I laughed when an archer came at me with his little pocketknife (when he's in melee combat and responds to an attack or attacks something from who-knows-where). It's awesome. I don't know how it works against a leveled-up hero, but neutral archers don't bother me anymore.
And what about the "Force Field" spell? Its purpose, unlike other spells, is that it completely prevents passage. It's funny when the gates are destroyed and you use this spell on the passage. Try it; you'll like it.
