Age of Empires Series Wiki

Perfusion is a technology in Age of Empires II: The Conquerors that is unique to the Goths and can be researched at the Castle once the Imperial Age is reached. Once researched, it doubles the working rate of Barracks, thus halving the train (research) time for units (technologies).


With Perfusion researched, the Goths become the fastest creator of military units in the game, making them able to create masses of Champions, Halberdiers, and Huskarls in a single minute whereas it takes several minutes for other civilizations to build up an army of similar strength.

Perfusion is increased even more with their team bonus, which adds a further 20% work rate boost for a total boost of 140%. Furthering this with Conscription (which should be researched before Perfusion), the total increase to the working rate of Barracks is 219%. When combined with Anarchy, the other Goth unique technology researched in the Castle Age, the Goths are capable of quickly and efficiently swarming their enemies with Huskarls.


Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, usually referring to the delivery of blood to a capillary bed in tissue. The name itself could reference how the effect of the technology produces a steady flow of units from a Barracks, much like blood.


A migratory people like the Goths had the ability to put armies in the field quickly. Their whole civilization was in a sense an army in the field. The youth of the Goths learned the skills of a warrior at an early age. The entire male population could become fighters in hours. Rivals learned not to let the Goths get close, if possible, and not to antagonize them if they did approach.
