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!

What are Cores and Where do I Find Them?

Cores are found in the Crystal Nexus. You can equip/activate up to four normal Cores at a time, and one Special Slot Core. Cores are generally purchasable or won in Events. They are a timed boost, so you activate them using the “Activate All” button. There are tons to choose from! As you can see from the top row below, you can set up presets for your most commonly used Cores  (Monster, Defense, Offense, Crystal, etc).

Dark World Cores

These Cores are only for use in the new Dark World. They can be found in the Moogle Market, won in Events, or purchased. The below stats are examples of Level 6. You can see all the cores and stats by going into the Nexus and poking on the locked Core.

Listed below are some of the more recent Cores (back about a year), and categorization of these. Note that some Cores appear in both the Attack and Defense categories. That’s due to the fact that they can potentially be used on either side.  These are listed from the most recent and go back in time. Not listed are the older Cores, but you get the picture.
