Diplomacy is a tier three technology that unlocks the Cloak, a stealth unit that infiltrates cities; the Embassy, a building that can only be built in another tribe's capital and grants additional stars per turn; and Capital Vision, which allows the player to see the capitals of tribes they have discovered (including capitals that have been captured).

Researching Diplomacy additionally allows you to see which players are at peace or at war with each other.
