"Catch someone trying to figure out if they want to hit you, or cast a spell, or defend themselves and bang! You got them."Confusion is a second-level chaos magic spell in Heroes of Might and Magic IV that costs three spell points and causes an enemy target within the line of sight of the caster to lose its next action.
This is a pretty solid spell. Your hero is able to immobilize one of your opponent's creature stacks, so the rest of your army can bring down the rest. Especially useful if you face a great number higher level creatures, and you normally could not kill them before reaching your army.
