It is low chance. You are considered lucky if you obtained it below 50 pulls. Even me without cheating takes about 300+ pulls to get it. Some people also said you have to clear the EoC chapter 1 or even to 3. But I never verified that.

What I know:

1. You do not have to pull it in row; You can like pull 25 times after clearing a battle, everytime you restart the app, etc.

2. No escalating chance; There is NO such thing as "If you've pulled 1000 times, the 1001th pull will guarantee you to get it"
