Effect & research conditions
The research costs 250 Food and 250 Wood. Villagers generate 0.03 Experience per second while performing any task; no special work assignment is required. Separately, Home City Card Coin costs are reduced by 25%. The card discount affects Coin only and does not remove other costs or requirements.
Research condition
Available to Haudenosaunee and Lakota from the Exploration Age. Research it at Tribal Marketplace.
When to research
Research when the economy can spare the initial resources and enough Home City Cards remain to use the discount. The Experience trickle accumulates while Villagers continue working, so it benefits a long match; the card saving is more immediate for a deck with expensive Coin shipments. Compare both effects with an urgent army or Age-up purchase.
Experience from ordinary work
Each Villager generates 0.03 Experience while carrying out any task. The worker does not need to stand at a special building or change jobs, so the trickle grows while the economy continues to operate.
Reduce the Coin portion of card costs
Home City Card Coin costs fall by 25%; other resource costs and eligibility rules remain. Cooperation is available to the Haudenosaunee and Lakota at the Tribal Marketplace from the Exploration Age and costs 250 Food plus 250 Wood. Its value depends on how long workers will remain active and how many Coin-priced cards are still useful.
