Crystal Nexus Overview

Today, the Hub turns to take a look at another important building: The Crystal Nexus. This building contains Crystal Cores that provide bonuses for your Empire. These bonuses engage when the Crystals are activated, and each lasts for a specific length of time. There is a cooldown for each bonus that limits the number of times they can be used in a set period. Each level of building unlocks a different type of Core, each with its own specific use.

Let’s examine each of these Cores, and see their effects and cooldown times. Find out which ones are right for your goals!
