"Onager (Level 1-3): These early catapults were based on ancient Roman technology, they used tensioned rope that when released launched stones at enemy fortifications."

"Catapult (Level 4-5): Catapults were increasingly important as a weapon to destroy castle fortifications as castles became bigger and stronger."

"Mangonel (Level 6-7): Mangonels were similar to trebuchets in that they used counter weights rather than tensioned rope to trigger the launch of projectiles."


  • Onagers have a damage bonus against towers and their shots do area-of-effect damage. Onagers are vulnerable to ballistae and trebuchet emplacements.
  • Onagers are basic siege units, unlocked from the Level 2 Siege Workshop.
  • Onagers are also known as Catapults or Mangonel depending on the upgrade level.
  • Area of effect damage.
  • Can defend itself from defending units,unlike trebuchet.
  • Fast enough to accompany teutonic knights.
  • Virtually invincible to catapult emplacements.
  • Does extra dmg to towers.
  • Slow

Offensive Strategy

  • Target a wall outside the range of a tower and one can take down one or two surrounding buildings or defense without taking any damage.
  • Usually not used when compared to trebuchets but can be used, maybe one, at the end of the battle to inflict some strategic damage and earn 2 stars.
  • Siege rush with Conrad the Elder is still good in Age VII: 2 trebuchets + 2 rams + 5 onagers + protecting units like mamluks

Defensive Strategy

  • Onagers CAN NOT be used in defense.
