Research
From ENDLESS Legend 2 Official Wiki
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. The base cost for every technology is the following:
- The Years of Survival technologies cost 24 Science
- The Years of Toil technologies cost 33 Science
- The Years of Invention technologies cost 42 Science
- The Years of Revelation technologies cost 51 Science
- The Years of Trepidation technologies cost 63 Science
- The Years of Reckoning technologies cost 360 Science
