There are 8 basic types of Crystals in the game.
You can improve the potency of your Crystals by combining two Crystals of the same level and type in order to get one new Crystal of a higher level. By repeating this process, you can upgrade Crystals to a maximum Level of 12. The higher the level of the Crystal, the better the bonus it will grant to your forces once activated.

To combine Crystals, go to your Sanctum of Shards, open the "Sacred Chamber" tab and choose the Crystals you wish to combine. You will also be able to see the bonus you receive once the Crystals are combined together. Click "Combine" to produce the higher level Crystal. Once combined, the Crystal will be immediately sent to the Cache.
ATTENTION: To upgrade the Crystals of higher levels you need to upgrade the Sanctum of Shards.

You can receive Crystals by:
- Purchasing Crystal Coffers with Crystals at the Black Market within the "Misc." tab;
- Participating in Global Tournaments;
- Challenging other Leagues;
- Attacking or defending Battlegrounds;
- Other game interactions.

All Crystal Coffers acquired will be sent to your Cache within the Sanctum of Shards, where you may open them and extract Crystals.

To use and store Crystals, you must first build the Sanctum of Shards. All Crystals gained in the game are stored in the Cache at your Sanctum of Shards. To view a Crystal's attributes, simply place your cursor over it. To apply any Crystal and benefit from its bonuses, simply place it into any open Activation Slot on the Activation Board. BE AWARE: You must use a Seal of Weor to open additional Activation Stots. Crystals are permanent bonuses, and will not disappear from slots unless you decide to remove them.

Once applied, you can only safely remove Crystals and return them to your Cache with the help of special tools – Celestial Wands. This tool can be purchased from the Black Market. Removing the Crystals without the help of a Crystal Wand will result in the Crystal being permanently destroyed!

Keep in mind that there are two types of Celestial Wands:
Eir's Celestial Wand can safely remove Crystals of Level 5-8
Weor's Celestial Wand can safely remove Crystals of Level 5-12

WARNING: Each Celestial Wand is "single-use" only and may be used to extract only ONE Crystal.
