Research

Every technology will unlock between 1 and 4 units, structures, or empire-wide powers or bonuses. Technologies are researched by using Science and their cost increases based on their era and the number of technologies already researched. To better indicate what they're used for, all technologies are shown in one of four domains: Society, Economy, Discovery, and Defense.

Technologies in Endless Legend 2 are divided across 6 eras. Only technologies from the current and previous eras can be researched but once 8 technologies from the current era have been researched the next era will be reached. Reaching an era unlocks various bonuses depending on the played faction.
