i back to home and see my cube . the purple will expire if dont open in 5hour but the yellow not! and i stay in yellow for 10 days dont open
Almost 3 months more or less, no practonium.
same since one week after r8 patch release, no practonium for my first cube
Can I ask somthing. For you guys having problems to get your Practonium for weeks/months:
Are you opening the Mystical Cube in a fixed time every day? Like, if you open first time at 10 am, are you keeping it always at 10 am or just opening it randomly whenever you remember?
I have the slightly impression that the cubes when I was more strict with my time to open them gave Mithril Ores in a better rate than the current one which I was opening randomly, then on my last cube I wasn’t being so strict, my Mithril Ore rewards are quite rare on this one.
Got mine yesterday after 70something potion so happy
I’m opening it whenever I remember :I
i thinks its only lucky, dont depend time lol… some ppl say to me wait 5h for open -.-
