Chemistry
Enables gunpowder units and strengthens eligible ranged attacks.

Overview
Enables gunpowder units and strengthens eligible ranged attacks.
Effect and affected units
Chemistry changes +1 attack for ranged siege units, archers, ships, and defensive structures. The affected target is ranged siege units, archers, ships, and defensive structures; the bonus does not automatically apply to the rest of the roster. 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 University. The recorded cost is 300 Food, 200 Gold, and the research time is 100 seconds. Consider whether the upgrade will affect enough units or workers to repay that investment before the match is decided.
Matchup plan: Chemistry gunpowder-versus-range timing
Chemistry unlocks gunpowder options and can strengthen a ranged plan, but its value depends on the civilization and army. Compare it with Bracer when you need range and general archer support Research Chemistry when Bombard Cannons, Hand Cannoneers, or other gunpowder units are part of the next push. Use the new units with a screen and keep their gold cost in mind when balancing the economy. If the army is primarily archers and needs range, compare Bracer’s broader support before spending; continue scouting so the research answers the actual composition Chemistry does not affect every projectile unit, and some civilizations or unit lines gain little from it. Gunpowder armies can consume gold quickly, so do not unlock them without the income and protection to field them
Effect and research timing
Enables gunpowder units and strengthens eligible ranged attacks. Effect: +1 attack for ranged siege units, archers, ships, and defensive structures. Research becomes available in: Imperial Age; Research at: University; Research cost: 300 Food, 200 Gold; Research time: 100 seconds. 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.
