Mystic Gem

Mystic Gems are a new currency introduced in the "Wrath of the Dragon" season. Like Magic Powder, Mystic Gems serve only one purpose: blessing normal S-grade evolved Treasures with a 100% chance.

Extracting Evolve Treasures
Mystic Gems, like Magic Powder, cannot be bought with Coins, Crystals, or cash. They can not be found in events as well. They can only be obtained through extracting S-grade evolve Treasures.

The amount of Mystic Gems a player gets depends on four main factors:
 * The upgrade level of the Treasure before extraction
 * The grade of the original Treasure used for the evolution
 * The ingredients used to evolve that Treasure
 * Whether the Treasure was blessed or not blessed

Currently, the highest amount of Mystic Gems possible from a single treasure is 88 and 150, for non-blessed and blessed treasure, respectively.

Trading with Medals
The only other way to obtain Mystic Gems is through the Medal Exchange Center. There is only one set to trade with, and that is 50 for  3,000.

Advice
Since having S-grade evolve Treasures is hard to obtain and requires having many ingredients and Treasures, you need to make a priority system, like with Magic Powder.

Trivia

 * No pets, cookies, currencies, or Fortune Dough can aid in obtaining extra Mystic Gems.
