The Celtic Technologies are the improvements available to the Celtic Civilization. They are originally researched at the Palace, and then each technology must be researched at it's specific building during the mission. Some Technologies listed here are exclusive only to this civilization. With the Summer Update how each civilization gained points was revised. All technology costs 1 point to unlock, for a total of 52 purchasable techs. Each Civilization level upgrade gives you 1 Tech Point, except for Levels 3,7,15 which now give 5 Tech Points.
- Rites are considered semi-technologies because they cannot be researched but are still in the technology tree and is part of Augur skill directly.
