Siege Engineering is a technology in Age of Empires IV that can be researched at the Blacksmith or Forge starting in the Feudal Age. Once researched, melee and ranged infantry can construct Siege Towers and Battering Rams or Cheirosiphons in the field.
Civilization bonuses[]
Abbasid Dynasty: Siege Engineering is free implicitly. Infantry units are able to construct Battering Rams and Siege Towers (from the Dark Age), Springalds and Mangonels (from the Castle Age) without researching Siege Engineering.- Ayyubids: Siege Engineering is free implicitly. Infantry units are able to construct Battering Rams and Siege Towers (from the Dark Age), Springalds, Manjaniqs and Towers of the Sultan (from the Castle Age) without researching Siege Engineering. Cavalry can construct siege with Military Wing: Reinforcement.
- Byzantines: Can build Cheirosiphons instead of Battering Rams. Research speeds are 30% faster per water level at buildings within the influence of a Cistern with the Dialecticus ability active.
- Chinese and Zhu Xi's Legacy: The technology researches 150% faster when the Blacksmith is supervised by an Imperial Official. For Zhu Xi's Legacy, this can be improved to 300% faster after researching Regional Inspection.
- Delhi Sultanate: The technology is free, but takes 3.5x as long to research (105 seconds instead of 30 seconds).
- Holy Roman Empire and Order of the Dragon: The Meinwerk Palace works 50% faster and the technologies are 50% cheaper.
- Malians: Technologies take less time to research based on how much gold has been obtained through trade.
- Mongols: Blacksmiths near an Ovoo can research Improved Siege Engineering for 175 stone that allows melee and ranged infantry to construct Springalds, Mangonels, and Traction Trebuchets in the Castle Age.
Changelog[]
- Originally, Siege Engineering took 60 seconds to research. With Season Two Update 17718, it took 45 seconds to research. With patch 20249, it takes 30 seconds to research.
Trivia[]
- While the Mongols can research Improved Siege Engineering in the Feudal Age, it has no effect till reaching the Castle Age.
Campaign version[]
Because the four original campaigns have not been rebalanced since the release of the game, Siege Engineers in those campaigns costs 25 food, 150 gold and takes 60 seconds to research. The effect is the same.
