Gems is the only currency that counts toward the VIP level of the player and any purchase of Gems, be it directly or indirectly (as part of various promotions), is added to the VIP level. In the bottom-left corner of this screen, the icon is shown, indicating the player's VIP level inside, and next to it the total amount of Gems the player purchased separated by a / from the total amount of Gems needed to reach the next VIP level. Pressing the button will take the player to the VIP interface. Additionally, in the bottom-right corner, opposite of the VIP level information, the 120px option can be used to restore the player's earlier purchases in case they were lost or not recognised after changing devices. This option is only available to Android and Windows users.
Purchasing Gems can also be done through the Shop, a small building situated underneath Chronos. Whenever there is a promotion for Gems, the icon will be shown atop the Shop.
During Gift Giver promotions, whenever a Clan member purchases 50 or more Gems, all of their Clans' members will be awarded gifts. The type of gifts and amount of each that will be awarded will depend on the number of Gems purchased. The player can choose to hide their name from being seen by the other Clan members when they receive their gifts.

- To speed up any amount of time, the option has to be pressed after selecting what is to be sped up. A confirmation window will pop up and pressing the button will confirm the choice, provided the player has enough Gems to pay the cost.
- There are two factors that influence the cost of speeding up timers, namely the duration and the feature. For example, the same amount of time for cooldowns in the Enchantment League and those when breeding does not have the same cost.
The formula for speeding up timers in events is as follows:
(TimeInSeconds ^ -0.5) * 0.1 * TimeInSeconds
The formula for all other timers that can be sped up is as follows:
(TimeInSeconds ^ -0.46) * 0.12 * TimeInSeconds
The final result is then rounded, in the following intervals, as follows:
- 1-10: 1
- 10-100: 5
- 100-200: 25
- 200-1,000: 50
- over 1,000: 100
- The cost to speed up the hatching time of the Water Dragon (5 minutes): (300 ^ -0.44) * 0.15 * 300 = 3,6 - rounding by 1 applies, thus the cost to skip the timer is 4 Gems.
- The cost to speed up the waiting time in the first challenge of the Boss Challenge (4 hours): (14400 ^ -0.5) * 0.1 * 14400 = 12 - rounding by 5 applies, thus the cost to skip the timer is 15 Gems.
- The cost to speed up upgrading a Dragon's skill to Level 2 at the Academy (3 hours): (10800 ^ -0.44) * 0.15 * 10800 = 27,2 - rounding by 5 applies, thus the cost to skip the timer is 30 Gems.
- The cost to speed up the breeding time of a Legendary Dragon (2 days): (172800 ^ -0.44) * 0.15 * 172800 = 128 - rounding by 25 applies, thus the cost to skip the timer is 125 Gems.
