Heroes are seperated into three categories: a civ's general or ruler, chosen via policy decision and available for use only once, editor-only heoes, or multiple heroes such as Rhenish Knights or Condotierri. Hero units have the following special attributes:
- They self-heal.
- They are immune to conversion.
- Their combat stance (see the Age of Empires Series Wiki for more information on this) is set to Defensive, as opposed to Aggressive.
