Grand Trunk Road
Gold income is faster and trading fees are lower.
Overview
Gold income is faster and trading fees are lower.
Effect and affected units
Grand Trunk Road changes all gold gathering is 10% faster; Trading fee reduced to 10%. The affected target is 10%; 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 Castle Age at the Castle. The recorded cost is not separately recorded, 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: Grand Trunk Road gold-income plan
Grand Trunk Road strengthens several Hindustani gold sources, making it a priority when the army depends on gold and the economy can use mining, trade, or Relics. Develop the income paths before the map runs dry Keep Gold Miners active and protect their camps, then establish safe Trade Cart or Trade Cog routes as map control allows. Secure Relics with Monks and use the improved income to maintain Camel Riders, Hand Cannoneers, or Bombard Cannons. Research the technology before the late-game gold crunch so its benefits accumulate while you still have time to establish trade The bonus does not protect exposed trade routes or mining camps. If no safe route exists and gold remains abundant, spend on immediate production and defenses first; scout for trade opportunities before relying on the technology
Effect and research timing
Gold income is faster and trading fees are lower. Effect: All gold gathering is 10% faster; Trading fee reduced to 10%. Research becomes available in: Castle Age; Research at: Castle; 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 payoff is economic: the benefit accumulates through later work, so researching it earlier leaves more time for the improvement to matter.
