Technology

The technology tree of a Xin-xi player with all technology researched.

The technology tree icon

Technology is research that unlocks new resources, buildings, units, and/or abilities. Technology can be researched using stars and discovered in ruins. Each tribe, except for Luxidoor and Aquarion, has a unique starting technology that is unlocked at the start of the game.

Technology is divided into three tiers. Tier one (T1) technology can immediately be researched at the start of the game, while tier two (T2) and tier three (T3) technology can be only researched after the previous technology in their branch is unlocked.

The cost of a technology depends on its tier and the number of cities controlled by the player. Initially, tier one technology cost five stars, tier two cost six, and tier three cost seven. For each additional city the player controls, research costs increase by one, two, or three stars for T1, T2, and T3 technology, respectively. In other words, the cost of a technology is calculated as follows: (technology tier) × (number of cities) + 4.

The Literacy icon

Literacy, an ability unlocked by the Philosophy technology, reduces research costs by 33%. (Discounted costs are rounded up to the nearest star.)
