I guess everyone here know a bout the Brilliant Mystery Potion which give you a mystery gift everyday for 5 continuous days.
My first potion is Quest Potion and it made me sad. It didn't give me good or useful cards.
So I've tried to collect all my DEC throughout the season and finally I purchased a Brilliant Mystery Potion.
Day 1 I received a reward card that made me almost wanna cry !!! WHAT AN EXPENSIVE POTION! AND ONLY A REWARD CARD! (Sorry I didn't screenshot it.)
Day 2 I got an ORB !!!! HURAY !!! AT LEAST AN ARMORSMITH!!!
Day 3 T . T
Day 4 ┴┴︵╰（‵□′）╯︵┴┴
IT'S THE LAST DAY AND MY LAST CHANCE TO HAVE GREAT CARDS!!
Day 5 I got another Armorsmith !!! Not bad.
SO DOES THESE PRIZES WORTH FOR 6000 DEC?
For 2 days of quest rewards, I've received MANTICORE.
