Crystal

Crystal is the "money" in the game.

It is harvested from fountains and some can also be found when claiming treasures.

There are 5 types:

• Rubinum
• Gelbur
• Hadranium
• Azon
• Moviridium

They are "equally valued" but every player is attuned to only one of them, meaning that you can gain that type a lot more easily, but you also need it more to spend in your Base when building and upgrading facilities.
