Age of Empires Castle Siege Wiki

"These proto flamethrower troops were, by the tenth century, a common and effective part of Byzantine fighting forces."


  • Cheirosiphons spray Greek fire across short distances to inflict massive damage. At close range, they are deadly. Shield them with tougher troops to get them in close.
  • They attack with flame, ignite buildings and units, doing damage over time.
  • Deadly in close combat.
  • Easily killed by long ranged troops.
  • Slow.

Offensive Strategy

  • Cheirosiphons can swiftly destroy melee troops.
  • If protected by a meat-shield, can be used to take out towers very quickly (used much like crossbowmen)
  • Ranged units can swiftly destroy them.
  • Can be used as a sub-siege weapon, as at lower age levels, if not being fired upon, Cheirosiphons can swiftly take down walls.

Defensive Strategy

  • Cheirosiphons are an excellent choice for the Guard House or the Patrol Point. As long as the guard house still stands they become very effective the longer the battle. Most units other than Longbowmen and Mamluks have to engage them and receive high damage.
