Crystals are a building in Dragon City, which affect dragons of the same type within a 10 and a half tiles radius and can be placed anywhere on the map. They grant a 20% increase in gold production for all dragons of the matching element in any Habitat within the radius. A dragon can receive boosts from multiple crystals, as they only need to have the same element as the crystal's element. Also, double element dragons will get twice the boost of the corresponding Crystal (since they have 2 times the same element). For example, the Double Terra Dragon and Double Flame Dragon will get 40% gold boost from a single "Terra Crystal" and "Flame Crystal", respectively. However, not all elements have their own crystal boost. Here's the list of crystals available in the game :
