Druzhina is a technology in Age of Empires II: The Forgotten that is unique to the Slavs and can be researched at the Castle once the Imperial Age is reached. Once researched, it makes infantry deal 5 damage to adjacent units in a 0.5 tile radius.
Druzhina is the cornerstone of Slavic armies in the Imperial Age, benefiting both Halberdiers and Champions. As it allows both of these units to deal damage to adjacent enemies, it makes massed infantry units formidable for large battles, where armies tend to clump up, leaving them vulnerable to the splash damage. Researching Blacksmith technologies beforehand should not be disregarded, particularly given that Druzhina is the second most expensive unique technology in the game (in terms of raw resources). Only Flemish Revolution is more expensive (since update 50292).
With Druzhina, the Slavic infantry may be the strongest in the game in massed battles, being able to defeat large infantry armies of prominent ones like Aztecs, Burmese, Bulgarians, Japanese, Teutons, and Vikings.
- Druzhina also affects ranged infantry units. In most cases, this is redundant, as the Slavs cannot train any ranged infantry units.
- With update 34699, Druzhina does not affect ranged infantry units anymore.
The Druzhina (Polish: drużyna, Russian: дружина, lit. “Squad”) was a group of men in early Poland and Rus who helped the prince administer his principality. Among the first members of druzhina were actually Norse warriors. They were eventually joined by members of the local Slavic aristocracy and adventurers from various nationalities. The senior members of the druzhina were known as boyars and acted as the prince's closest advisers. After the 13th century, the term druzhina fell out of use.
