60M Celebration! Miraculous Magic Powder Hourglass is an S-grade treasure celebrating 60 million downloads of LINE Cookie Run app. Players who log in from 23 September 2016 until 14 November 2016 were eligible to get this treasure for free without any requirement.
When given as a reward, the treasure appeared as an A grade Treasure, due to its golden border and it had the POWER+ label. This showed up only when you got the treasure, after that the treasure was seen in the Treasure Cabinet as an S grade Treasure.
The amount of Coins and Crystals needed to upgrade the Treasure was the same as for A-grade Treasures though.
For some reason, the name showed when the reward was obtained was "60M Celebration! Miraculous Magic Powder Clock", but when visiting the treasure Cabinet it was changed already.
