Research

Research, also known as tech or technology, is a key feature. Players can improve their tribe or unlock new things. Researches' cost increase with each new city.

Each path is composed of a basic tech followed by two secondary paths. The first one is economic and the second one about military

A Mastery is available at the end of each path. Masteries take one turn to research. During that time, no other research can be done

Certain tribes may have free research unlocked from start called tribe tech
