Effect
The benefit applies to Wood collection at the listed natural sources. Water Wheel begins the Asian wood line; Regenerative Forestry follows in the Commerce Age, though starting benefits and availability can differ by civilization.
Research condition
Chinese or Japanese; Exploration Age; Asian Market; 50 Food; 15 seconds. Increases Villager Wood gathering from trees and Mango Groves by 5%.
Research decision
Research early if Chinese or Japanese Villagers will continue gathering Wood from trees and Mango Groves. The 5% gain is modest, so its value comes from sustained chopping rather than a short burst. Check whether the civilization already receives the effect before spending resources, and preserve the next age-up or unit budget. Regenerative Forestry is the Commerce Age follow-up, with access differing by civilization.
A small first step in the Asian Wood line
Water Wheel increases Villager Wood gathering from trees and Mango Groves by 5%. It does not increase construction speed or gathering from mines and Fields. The effect is most noticeable over time with workers continuously assigned to logging.
Check civilization access before researching
Chinese and Japanese can research it at the Asian Market in the Exploration Age where the benefit is not already granted. Regenerative Forestry follows in the Commerce Age, but starting effects and access can differ; verify the active civilization’s option before budgeting the upgrade chain.
