How do I earn Crystals in the game?

The easiest way to earn crystals is to complete quests. You will receive a few crystals for each completed quest. You can also find crystals in special chests which are scattered all over the map. And you can always buy the required number of crystals in the resource store.

To buy the crystals, open the resource's store. Press the button "+" on the top resource bar and select the required amount in the pop-up window.

If you do not receive the crystals after purchase, contact the support of the store where you downloaded the game.
