Hualcana
Hualcana is a Fortress Age technology for the Incas, researched at the War Hut. It increases the resistance of Infantry and Shock troops by 5%, improving the durability of those categories rather than their attack. The listed cost is 50 Wood and 500 Coin, and research takes 10 seconds. Its broad class coverage can affect several parts of an Inca army, but the stated bonus does not imply that Cavalry, Artillery or Villagers receive the same effect.

Effect & research conditions
Research Hualcana at the War Hut once the Fortress Age requirement is met. The resistance increase helps the eligible troops absorb incoming damage; it does not remove their counters or replace unit composition and positioning. Apply the bonus when evaluating the staying power of Infantry and Shock troops, and keep other unit classes outside that expectation.
Research condition
Incas; Fortress Age; researched at the War Hut; costs 50 Wood and 500 Coin; 10-second research time; Infantry and Shock troops gain 5% resistance.
When to research
Consider the upgrade before a sustained fight in which a substantial part of the army belongs to the affected classes. Its 500 Coin cost is significant, so compare the defensive improvement with the cost of adding or replacing units. It is especially relevant when those troops are expected to hold a line while other units attack.
A defensive bonus for two Inca unit classes
Hualcana increases resistance for Infantry and Shock troops by 5%. The bonus supports eligible units from both classes, rather than granting hit points or improving every Inca unit. Check the classification on a unit’s profile when its role is unusual; cavalry-like Shock Infantry and ordinary Heavy Infantry may interact with different enemy counters.
Research at the War Hut for a sustained force
The technology is a Fortress Age Inca War Hut option. It is most relevant when a substantial part of the army belongs to the affected classes and will remain in combat long enough to benefit. The resistance does not remove a unit’s counter matchup, so retain suitable support and compare the research with immediate replacements.
