Whenever you have two or more people that are friends in an army, they will do special tactics together if you set them up correctly (such as a Double Blade, Family Bond, and Triple Strike). Others will have tactics that will do other things. For example, if you have Sun Ce and Sun Quan together in a tactic combo, they will do the tactic Conqueror. If you have Lu Ling Qi and Lu Bu together, you will do the special tactic Warrior's Blood. Note: Conqueror and Warrior's Blood can only be used once in a battle.
