My tips
-Remove inactive (10+ days) friends. They can't open your chests and you cant open theirs. Try to avoid people with certain people who open up all their pink chests. I had someone who was opening around 95% of mine so I removed him.
-Save namins till phase 2.
-save egacha till phase 2. You'll be able to get twice as much out of the alphas since they will be betas for next event.
-save glasses for phase 2.
-Only use glasses on 5 step ups. Don't use them to advance stages since your sacrificing at least 100 of w/e things were collecting each time.
-If you get to a battle and you don't have the focus to kill it you can just close the explore window and wait till you do. It will still be there whenever you open it back up.


Pro tips
-Don't sleep and open lots of pink chests
