Greek Fire
Fire Ships and several defensive weapons gain range or blast radius.

Overview
Fire Ships and several defensive weapons gain range or blast radius.
Effect and affected units
Greek Fire changes fire Ships +1 range; Bombard Towers +0.5 blast radius; Dromons +0.2 blast radius. 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 Castle Age at the Castle. The recorded cost is 250 Food, 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: Greek Fire Byzantine shoreline pressure
Greek Fire extends the reach of Byzantine Fire Ships, helping them engage enemy fleets and pressure coastal targets from farther away. Use it to strengthen a fleet that already has numbers and support Build a Fire Ship group and research Greek Fire when sea control or shoreline attacks are important. Use the added reach to start engagements against Galleons and threaten Docks or other coastal structures, while keeping a second line ready to screen transports and protect Fishing Ships. In later ages, coordinate the fleet with Dromons or coastal defenses to pressure several shoreline targets Fire Ships remain short-range compared with other vessels and can be overwhelmed without backup. Keep the fleet moving, avoid charging into a larger formation, and do not leave transports or fishing income undefended while pursuing a coastal target
Effect and research timing
Fire Ships and several defensive weapons gain range or blast radius. Effect: Fire Ships +1 range; Bombard Towers +0.5 blast radius; Dromons +0.2 blast radius. Research becomes available in: Castle Age; Research at: Castle; Research cost: 250 Food; 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.
