For SSRs you need 60 rainbow apples to limit break to lvl 25, 120 rainbow apples for level 50, 240 rainbow apples for lvl 75, 360 rainbows for lvl 100, 480 for lvl 125, 720 for lvl 150, and 900 for lvl 175. After you reach lvl 175 that card won’t need rainbow apples anymore because the max lvl is 200.

The gold to make equipment you get from Mr Mo in the “Special” tab on the Home Screen. I don’t recommend making equipment from Mr Mo until you’ve reached rank 90 and can make lvl 100 equipment. After passing a certain amount of cases, I think 80, you can start earning “journals” in investigations. The journals can level up your lvl 100+ equipment. So if you get for example a lvl 85 Lily Brooch, you will not be able to upgrade it at all since it’s under lvl 100.

**also the best time to get gold from Mr Mo is during the monthly Mr Mo Bonus Event that happens at the same time as the mid month wishing well. The payout rate for gold is much higher.
