I took on the campaign with Lord Ironfist.
Teleport is probably one of the best magic spells in Heroes I for taking a castle if you have no flyers. Position your (what i like to call rock) in front of a powerful range. Range melee attack is low so you will be a solid rock for a few rounds while you carnage all around. Too bad my Cavalry unit was too large to fit inside the walls. :)
Quick glimpse of the spell.
