Cores – Crystal Nexus

Latest updates on the Crystal Nexus and how the new Cores benefit your Empire!

As we know in Final Fantasy: A New Empire, the Crystal Nexus building grants extra boosts for your Empire by unlocking and using unique Cores. Sometimes we run to an issue where we are unsure whether it is worth switching them around at certain levels, and under those circumstances, it becomes a pain to continually scroll up and down to remember the stats to them. In this guide, we will cover the additional boosts that become available over time as well as the latest Cores. Also, a comparison to see how strong they are versus the last Core release, and also some preset recommendations whether you are looking to attack a Vault or defend your Empire.

Side note, if your building is not maxed out, then be sure to check the Crystal Nexus Blueprints Requirements section! With this in mind, please read below to get caught up with the latest news on the Crystal Nexus.

Crystal Nexus Additional Boosts

Beyond the whole purpose of the Crystal Nexus, it also provides you with extra benefits to accelerate your Empire even further. After the Dark World came out, most of the Auxiliary Buildings that were released before it became unworthy of our attention. When new Auxiliary Buildings came out, the Blueprints required for it became more universal. In other words, this is helpful for us as we will not be required to accumulate or purchase specific Blueprints for each of the individual buildings. 

Hence, now they include stats that are relevant to our Empires. The Crystal Nexus itself helps you boost your Airships, Cavalry, as well as your Elementals. 

Overall additional Crystal Nexus boosts:

  • Dark Airship Attack 
  • Dark Cavalry Attack 
  • Dark Elemental Troop Attack with Hero
  • Dark Elemental Armor 

In the meanwhile, check out how much Blueprints you need to level your building!

Crystal Cores

Each of the Cores is permanent and can be reused one the cooldown period is over. You may only use one type of Core at a time, but you can use up to four different ones to your benefit to aid your gameplay. You may also create presets for the Cores like you can do with Gear and Gems. Setting presets will be very helpful should you confront a situation such as when you are attacking, then need help defending. 

Read below all about the new Cores.

Keep in mind, each of these Cores below has a 4-hour duration and a 30-minute cooldown period.

Gilgamesh Core

This Core is excellent for your Hero overall, it provides additional boosts to your Hero, Guild Adventure Halls, in addition to when your Hero hits the monsters.

This particular Core benefits you with your Supreme Vault/Mini Vaults and your Forts when it comes to attacking and defending it. Do not forget to power up your Power of Kings Hero Trees to push these stats even further. Check out the Supreme Vaults and the Disputed Realm Articles for more in-depth information about them!

  • Vault Dark Troop HP – 15B%

How do they compare with the ones released beforehand?

Not only are some of the new Cores have increased stats all-around, but they are also much more precise on what it helps you with. Now the ultimate question would be, because of how strong these new Cores are therefore should we use them at a lower level or not? For this reason, check out an example to see the differences!

Level 6 Chaos Core vs. Level 1 Meteorite Core 

Level 6 Chaos Core

  • Dark Astral and Mount Attack – 250M%
  • Vault as well as Disputed Realm Dark Troop Attack – 1.1B%
  • Vault and Disputed Realm Dark Troop HP – 800M%

Level 1 Meteorite Core

  • Vault Dark Troop HP –  4.92B%
  • Vault Dark Troop Attack – 16.4B%
  • Disputed Realm Dark Defense Attack – 3.6B%
  • Disputed Realm Dark Defense HP and Armor – 1.64B%

As you can see above it just at level one, it is significantly an improvement from the last Cores released. 


The Crystal Nexus now contains presets to service your needs more. As a result, this can be extremely advantageous and convenient to have at a click. Remember the time when we had to swap out each Gear pieces to change them up, ESPECIALLY when we had to swap to the defense set before a march arrived? Talk about anxiety! 

More importantly, the presets would be useful if you are using your Hero in the Hall or even hitting Monsters, then suddenly have to defend your Empire from an upcoming battle. Or if you are solo attacking someone, then decide to hurry and rally them before they get online.

Astral Shard Core

Firstly, I think we can all agree that the Astral Shard Core is worth it for every style of gameplay in terms of attacking, rallying, defending, Neutral Cities/Realms, and Crystal battles. To clarify, with the Multi-Defense Astral boost, it will be handy in multiple situations. 

Creature Core

Secondly, the Creature Core, it may not be as useful as the Astral Shard Core, but it does benefit you in more than one circumstance. The only slight downfall to this one is that it will only help the active Mount that is summoned. But, with the stats being phenomenal, it’s worth having for just about every style of gameplay as well. 

Vault/Disputed Realm

Consider taking advantage of the ones specifically made for Vaults of Forts on top of the other boosts you can obtain from Heroes. (ahem.. such as your King Noctis and Ardyn’s Skill Tree..) Also, your Power of Kings (remember they are like Mastery Skills, being passive no matter what Hero you use!). 

Use your Meteorite Core, Ardyn’s Corrupted Soul Core, and also your Chaos Core.


With the new Cores out, it does put an excellent addition into the Defense as well as the Trap Empires. 

Use your Astral Shard Core, Creature Core, Dark Daemon Core, together with your Dark Meteorite Core.

Doing so would provide significant boosts for you, especially if you become a Mercenary and Elemental Empire purely. The four Cores would boost all your Astrals, your active Mount (your Ebony Chocobo or Sinistercorn depending on their levels), Mercenaries, as well as your Elementals. 

It is essential to utilize your passive skills such as Mastery Skills, Power of Kings/Queens/Veterans, as well as your Oracle Temple. Also, since you likely have Multi-Astral Defense, make sure you are skilling them as you level them up to your advantage since they all will be used.


The Crystal Nexus now assists your Empire in more ways than one by allowing you to use four new Cores every half an hour. Also, increasing your passive stats on Airships, Cavalry, and Elementals. It is important to remember that the Gilgamesh Core is fantastic to use for your Hero when hitting monsters or the Guild Adventure Halls. And the Ardyn’s Corrupted Core is great for Rallies.
