Druzhina
Infantry damage nearby enemies when they strike.

Overview
Infantry damage nearby enemies when they strike.
Effect and affected units
Druzhina changes infantry +0.5 radius blast radius [flat 5 damage]. Read the named target carefully: this effect applies only to the units, buildings, or economy described in its entry. This is the main reason to research it; compare the affected units with the army you expect to field.
Research cost and timing
Research is available in Imperial Age at the Castle. The recorded cost is 500 Gold, and the research time is 40 seconds. Consider whether the upgrade will affect enough units or workers to repay that investment before the match is decided.
Matchup plan: Druzhina Slavic infantry-mass timing
Druzhina lets Slavic Champions and Halberdiers damage nearby enemies, making a dense infantry group especially effective in crowded fights. Build and upgrade the infantry mass before paying for this expensive improvement Secure the relevant Blacksmith upgrades and establish continuous Champion or Halberdier production, then research Druzhina for a sustained Imperial Age push. Keep the infantry compact enough for units to reach adjacent targets, while siege and ranged support handle buildings and threats that can kite the formation. Use the splash to win fights around narrow lanes and protect the siege as it advances The technology is costly and its value depends on fighting at close range. Do not let the infantry mass chase archers across open ground; preserve the group with screening units and choose terrain where it can stay in contact
Effect and research timing
Infantry damage nearby enemies when they strike. Effect: Infantry +0.5 radius blast radius [flat 5 damage]. Research becomes available in: Imperial Age; Research at: Castle; Research cost: 500 Gold; Research time: 40 seconds. This research is restricted to its named civilization, so it is part of that faction’s identity rather than a shared option. Its value depends on which units receive the effect and how often they take part in combat; timing it before a major engagement can improve the whole eligible group.
