Supreme Treasure Chest

Supreme Treasure Chest can be bought for 25 from the Treasure Merchant. This kind of chest will obtain either A or S grade treasure. After the first purchase, players can choose to buy again with 20.

If players buy the Supreme Treasure Chest Big Set (6+1 S-A Rank Treasures) which can be bought for 119 Crystals, you will obtain 3 S-Rank Treasures guaranteed.

Supreme Treasure Chests are the most favorite choice of many players, being the only chest to tap on an expandingly large library of S-grade treasures. However the cost to open can be very high, even with the Big Set, and therefore players will need to collect more crystals by buying or by completing events and achievements.

Alternatively, players can get a Supreme Treasure Chest Ticket to get a free chance to open Supreme Treasure Chest at no cost. But players are not able to re-buy using 20.

Chest Figures
There are five different figures of Supreme Treasure Chest. Many players believe some kind of chest figure have a bigger chance of obtaining S-grade treasure rather than A-grade treasure, although there are no visible proof or evidence of this belief.

Trivia

 * If you open a Supreme Treasure Chest and it sparkles, the treasure inside has actually been downgraded from S to A. This is the opposite effect of the Great Treasure Chest as if you open a Great Treasure Chest and it sparkles, the treasure inside has been upgraded from B to A.
