Age of Empires Series Wiki

Sophisticated Mapuche legal system strengthens your social structure and lowers the Coin cost of your units.
—In-game description

Mapuche Ad-mapu is a technology in Age of Empires III: The WarChiefs that can be researched at a Trading Post built on a Mapuche settlement. Once researched, it reduces the coin cost of all units by 10%.


Mapuche Ad-mapu is useful for all civilizations, but can be especially useful for those reliant on coin-heavy units such as mercenaries or artillery. It does not reduce the cost of coin-costing villagers such as those of the Dutch or revolutionary Citizens, though the coin saved on the military can be used to make up for this.
