| —Age of Empires IV description | ||
Desert Citadels is a unique technology in Age of Empires IV: Knights of Cross and Rose available to the Knights Templar at the Fortress starting in the Feudal Age. After researching it, the Desert Outposts Fortress ability also grants +1 melee and +1 ranged armor to all military units except for siege engines. Worker units are not affected.
Currently, Desert Citadels also has a likely unintended interaction with melee units in that after gaining the armor bonus, melee units also gain the standard Desert Outposts +15% range bonus to their torch attack. Additionally, Serjeants gain the extra range on their melee attack.
