actually i just tried to search for a pattern,, i used 60pcs spell books for testing..
i tested epic beads for my ronan.. i have depleted beads(from the old gatcha event) then i tried the old pattern.. it didnt work,,
when i tried something (created own pattern), i got 7 gatcha parts..
hmm so.. 60pcs spell books for 7 parts + testing = not bad right? haha!
what ive done is
1. Open depleted beads 2(fail/without item [got aging cores) + 1 elena part
2. Open an epic sealed bead (of course for your desired job)
3. if you failed to open (2 depleted beads + 1 elena part).. do not open an epic sealed bead or else, you wont get any part..
hmm you will open 3 depleted then.. 2 for fail(aging core) and 1 for 1elena item
if you fail to open 2(aging core) + 1 elena part, close the gatcha window thing, then repeat step one until you got it.. (use common sense!)
P.S. i opened also the depleted beads of my Jin, and do the pattern, then open an epic sealed bead for my ronan then BOOM! a part of gatcha!
im just sharing what i saw/experienced..
and now i need some spell books to complete my set (unfortunately, i dont have money).
if you prove it and work for you, share me some of your LU! Load..
hahahaha!
im not telling you to follow this pattern....
