About Infirmary

Priority: High

The Infirmary heals wounded troops after combat, converting them from 'severely wounded' back into active forces. A high-level Infirmary directly determines how many troops you can recover after a battle, making it one of the most strategically important buildings for active fighters.

Upgrade Tips

1Never let your Infirmary lag behind your Barracks — losing troops permanently because your Infirmary was full is a costly mistake.
2Higher Infirmary levels increase both bed capacity and healing speed.
3Use herbs to speed up healing during active war events rather than waiting for natural recovery.
