So many rank up gems, but so little iso
So I just took nick and void to r5, and my iso is completely depleted. I have a 2016 rank up gem for magik from 3-4, a rank up gem for IMIW from 3/4, and a 2-3 and 3-4 2016 gem for OML. The problem isn’t gold, but iso. I tried grinding arena for prem shards, but those aren’t enough. Already done UC and master 100%. Any other ways to get iso?
