"The longer a siege, the worse it is for the attacker. So, ways must be created to topple a defender. Nothing surprises them more than flying right over their walls."Flight is a second-level order magic spell in Heroes of Might and Magic IV that costs three spell points and grants a friendly target the ability to fly until the end of combat.
This spell grants any target the ability to fly over stacks, heroes, obstacles, and walls. Especially useful in siege combat to bypass the normal attack on the drawbridge by jumping your stack directly over castle walls, the spell can also be used to deploy your stacks that may have become "trapped" by opposing creatures, or summoned illusions or creatures hemmed in by obstacles on the tactical map at the rear of your formation.
