Baldwin IV of Jerusalem is the final Boss army of the Holy Crusades Campaign.
Unit Type - Cavalier: Basic Cavalry Unit (No bonus, base cavalry dodge chance). Gambit - Charge: Deal Normal and Gambit damage to a single target.
His Bravery is mediocre, Tactics Good, and Magic low-medium. He has no special unit bonuses which hurts his value a lot.
He could be fun to toy around with and bring out his max potential to see just how powerful he can get, but you don't want to seriously use him past level ~25.
