if you can restart the game as many times you want per day , then this is the way to get crystals... 1) Start a new game, you don't loose your crystals. 2) just play till you have no energy left , at low lvls , the first time you really can have that is when you already are lvl 30. 3) restart game again , you won't loose crystals, repeat stap 2. also don't trade in your sets, if all sets full , crystals will fill the one that is empty ; so it fills white.
always press repeat when you are finished with the "Mind training" quest. you will always do puzzle boxes on your journey and just talk to the wiseman instead of travai.
wow, i found a way to farm crystals!
First of all, don't trade in. i didn't done it and im only recieving white crystals for now , because the others are full.
I don't know if it works with the daily gift too. For your own stats , money or other bonusses ; keep this comment alive
