It's all about luck. I've got treasures on both LINE and Kakao that failed only a few times and those that took almost 2M. Treasures with passive effects or from Cookies and Pets are generally easier to upgrade, but of course, that can never be verified unless DevSisters shares their codes.

Mostly for me, I expect to spend 1M fully upgrading an S treasure from 0 to 9. But I get surprises all the time, be it good or bad.
