Editing Difficulty level (section)

== AI behavior ==
In game against computer players, AI randomly gets one of three behaviors: '''Builder''', '''Warrior''' or '''Explorer'''. As a Builder, AI will act more in defense, focusing on the towns development, limiting the scope of exploring. A Warrior will seek to fight more with other players and capture neutral towns. An Explorer will focus on hiring more heroes and moderate aggression. He will sequentially explore the map. In addition, heroes of the Explorer type AI receive 50 more [[movement points]] at the start of each day.
AI behavior can also be defined in the map editor.
