Tupi Forest Burning
Tupi Forest Burning is an Exploration Age technology researched at a Trading Post or Tambo on a Tupi settlement. It reduces the Wood cost of Buildings and construction wagons by 20%, helping the Tupi establish infrastructure with fewer resources.

Effect & research conditions
Research costs 175 Food and 175 Coin and takes 10 seconds. The 20% discount applies to the Wood cost of Buildings and construction wagons. It changes the purchase cost, not construction speed, so the normal site, builder and construction time still matter.
Research condition
Available from the Exploration Age. Research it at Trading Post or Tambo on a Tupi settlement.
When to research
Research before a planned sequence of structures or construction-wagon placements, when the saved Wood can accumulate. It is a quick upgrade, but a single small building may not return the 175 Food and 175 Coin investment. Keep the settlement and chosen construction sites protected while expanding.
A Wood discount, not faster construction
Tupi Forest Burning reduces Wood cost by 20% for Buildings and construction wagons. It does not state a build-speed increase. Builders still need to reach the site and complete the structure, so plan the research around both resource savings and construction timing.
Time it before an expansion
The technology costs 175 Food and 175 Coin and takes 10 seconds at a Tupi Trading Post or Tambo. Its value increases with several planned placements; spend on immediate production if only one low-cost structure is likely to benefit.
