I had to refresh 12 (twelve) times to have Ling Ling stones appear once in the store. The chance for this is astronomical on equal odds. After buying it I refreshed it the 13th time and - surprise, surprise, no stones again.

Anyone had better odds or this is another artificial low rate hidden under "randomness" by the developers?

I refreshed 5 times and didn't see a single SS.

there are 13 heroes in CoF shop right now, and there are 6 SS slots. so there is a 46% (approx, IMHO) chance to see Ling in an Refresh.

It's about 62‰ to not see Lingling in any particular refresh. About 0.3‰ to go 12 without seeing her. But with 10's of thousands of players (at least) there are going to be dozens, possibly 100's of people that go 12 refreshes without seeing a particular hero.

But yes, it definitely sucks when it's *you* that "wins (loses?) the lottery".

rng lottery nothing more. some days it could be all ling ling. lilith's way to control progress

Yep. statistically it's pretty normal that this happens.

I got ling ling on my first refresh btw

Too bad for you :/
For me, she was there before I even restock COF store.

This is not how you calculate probability. I understand where you get 46%, 6/13. According to you, if there are 2 heroes and 2 SS slots then there is a 100% chance. No, it's 75% chance to see LingLing. LingLing in slot 1 , in slot 2 , in both or none which is 3/4. It is actually less than 1% , around .38% chance to see LingLing.

thanks

I may be the lucky one, i saw her in two spots the same day she was added to the shop.

More the heroes in the shop, harder is to get a specific SS.
