i've got to say a set of epic items in gacha is amounting from 700php (which is very lucky) to 1000php (that is if you keep your cool and do the pattern of 2-2 to 3-3 very calmly)
i know that it is depressing that the last piece is changing its pattern, BUT, i have done it all over again and gained 3 complete sets of armors for elesis, siegHart and arme doing the pattern and keeping it cool. I've been tempted by my first set if sieghart to gamble the last part as to no opening of 2 sealed beads first but it only takes a half of 60pcs scoll to pure gc club and QJs. but 1 thing that i've also learned, patience is needed if you need want the last pc.
