Returning Player: Needs Advice for Gems

[Yeoniie]

So I haven't played BNS in awhile, but after seeing the new updates I thought of coming back to see. However, need some advice on what gems to use. Would love to hear it from all of you. I understand that we need to have the attack power 28 diamond, (Hexagonal), so what comes after?

purple gem life drain

red gem crit

and then comes the others
