The Gem Cauldron is a feature that was implemented on February 17, 2014. It can be found on the Gem Collector's page once you have reached Trainerlevel 7. It is used to transform Gems into rare items by boiling them. The Gem Cauldron was updated on February 2, 2016. This update consisted of an entire new design and boiling method.
How to Unlock
You must have reached Trainerlevel 7 to unlock the Gem Cauldron, and it is required that you pay a one-time fee of 50,000 PD to repair the cauldron. You must then wait 24 hours for the cauldron to be repaired.
How to Play
The Gem Cauldron has many different recipes in which you can choose from. Some recipes are locked until you gain enough experience to unlock them. Experience is gained by boiling gems in the cauldron.
Each recipe shows an image of the item, and lists the required gems. Once you have the required amount of gems, click 'boil' to begin the game.
During the game, the image of the cauldron will appear with the required gems shown underneath. In the centre of the cauldron, a gem will appear. You must then click the matching gem underneath the cauldron. This process will be repeated until all gems have been used.
You are only given a certain amount of seconds to complete the minigame. If you don't succeed within the given time, you will get your gems back and have a 10-minute cooldown before you can try again.
If all the gems have been placed into the cauldron correctly, the cauldron will begin to boil and you must wait the certain time period given before claiming your prize. The waiting time can be cut in half with an Odd Incense. This item will be used automatically if you have one.
