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!

Our Recommendation

Crystal Nexus cores must be used strategically, as the cooldown period can be quite significant. We recommend that you try to arrange the activation of these bonuses close to or during events for optimum value. How do you make your Crystal Nexus work for you?

    So after the initial cooldown period are each of the boosts permanent? Or is the duration period it?

      They are permanent. You just have to wait to use them again for the cooldown period.

  2. Antwerp says

    I took it simply for the loyalty bonus on the guild missions and the better mats. Getting at least uncommon mats or better is a huge benefit and the loyalty is at least 50.000 if you collect the missions with ignis

    1. Zero says

      Shame you stop getting quest rewards at 50 or 51.

  3. pwninggrenades says

    Firefury core seems really strong, but ill probably be using the uncapturable hero core the most and the diamondsteel core
